Stuttgart and Hannover, Germany – According to the slogan “Factory of the future. Now. Next. Beyond”, the Bosch Group is presenting at Hannover Messe what the company already offers (now) for connected factories, what solutions will soon be available (next) and what it is developing for the future (beyond). Despite all connectivity and automation, humans and their creativity are indispensable in the Industry 4.0 era. Robots support them with complex and time-consuming tasks like data processing and quality control. This is also the message of 1.5 meter tall, Pixar-style 3D avatars. They take centre stage in Hannover and move around the virtual factory. All avatars are mock-ups of market-ready applications or pilot projects. Allow us to introduce them:ActiveCockpit – the Data CollectorThe intelligent communication platform ActiveCockpit from Bosch Rexroth visualizes data to make it easy to understand for everyone. Its gigantic screen informs employees about the production status by processing and visualizing production data in real time. As a result, manufacturing becomes more transparent, while faster information processing enables clear analyses and efficient procedures. Users and companies both benefit from the immediate identification of problems. This reduces downtimes and avoids potential recall costs; the quality level increases.IoT Gateway – the Personal Trainer

Despite the Industry 4.0 hype, some companies have not yet arrived in the digital age. The machines lack sensors, software or the connection to enterprise IT systems – and hence important prerequisites for the connected factory. The Rexroth IoT Gateway can quickly and easily connect both old and new machines for Industry 4.0. The IoT Gateway unites sensors, software and IoT-compatible industrial controls, making it possible to detect the condition of machines. Even operators of older machines can reap the benefits of the connected industry without large investments.

APAS assistant – the Team Player

Humans are key players in the factory of the future: creative intelligence is in the employees’ minds. They are supported by digital devices and robots. The collaborative production assistant APAS assistant, for instance, supports employees with monotonous and ergonomically challenging tasks – without a safety fence. This human-robot collaboration is made possible by an intelligent safety concept. Thanks to its sensor skin, the APAS assistant recognizes its human colleagues without touching them and stops before a collision happens. Once the employee has left the immediate vicinity, the robot independently resumes its work exactly where it stopped before. This interaction of human and machine leads to higher efficiency, and sustainable optimization of the overall productivity, since employees can concentrate on more complex tasks.

ActiveShuttle – the Delivery Guy

Robots also support with internal transport processes. They drive through the factory and, for instance, transport material cases from storage to the production station. With the ActiveShuttle, Bosch Rexroth presents a concept for an intelligent, driverless transport system that automates the internal flow of material and goods. The integrated lifting platform automatically unloads goods in the logistics and manufacturing areas. Cyclical transport or a consumption-based material supply can also be realized with ActiveShuttle.

XDK – the Messenger

The universally programmable IoT multisensor XDK (Cross Domain Development Kit) is the “midwife“ for companies, who want to develop their own applications quickly and flexibly. In a compact box, the XDK combines a variety of MEMS sensors, for instance to measure acceleration, rotation angle, humidity, air pressure or temperature, with a powerful processor for the analysis, processing and transmission of the sensor data. Be it for predictive maintenance, monitoring or retrofitting: the XDK can be deployed universally; the programming language XDK Mita facilitates programming.

Apart from the avatars, Bosch is exhibiting the following highlights:

Foosball: learning by playing thanks to artificial intelligence

Table soccer has to be learned. To do so, we absorb and digest information with our senses, in this case the eyes. With the help of our brain, we learn systematically how to hold, play or pass the ball with the right force at the right time. Artificial intelligence (AI) works according to the same principle: instead of the brain, software processes the information with algorithms; cameras and sensors replace our senses. The soccer table, also called foosball or KI-cker (KI is the German abbreviation for artificial intelligence), teaches itself and optimizes its soccer abilities with every new co-player. Industrial applications such as robots or autonomous vehicles can also learn numerous tasks and optimize their performance thanks to AI. Their biggest advantage: even after the umpteenth try, they will not be frustrated.

Smart Cab for connected farming

Smart Cab, co-developed by Bosch as a member of the CAB concept cluster, turns agricultural vehicles into connected control centres in the field. All components – vehicles, cameras and drones alike – can interact with each other. Via the cloud, camera drones send detailed pictures of the condition of crops to the driver’s cab, and operators are warned by the object recognition camera about living obstacles such as deer. Vehicle users can download specific functions from a feature store over the air directly to the machines. Depending on the weather or soil conditions, for example, the nozzle settings can be adjusted.

Nexeed – new Industry 4.0 software for production and logistics

Connecting the entire value stream

Hardware applications need innovative software solutions running in the background to provide the necessary connectivity. At Hannover Messe, Bosch is presenting its Nexeed new software portfolio, which pools Bosch software and services for production and logistics. The Nexeed solutions make day-to-day work easier for employees and optimize production and logistics processes in terms of transparency, agility, cost, quality and time. The portfolio ranges from the sensor, over machine automation to the cloud. Nexeed solutions can be combined to connect individual lines, entire plants and plant networks, as well as their intralogistics and external goods flow.

Systematic production improvement

The Nexeed Production Performance Manager, for example, ensures systematic improvement of production by helping employees with decision making. For this purpose, the software collects and harmonizes production and machine data from many different sources and “translates” them into a common language. Subject-specific functions like the Ticket Manager, which was developed for the lighting company Osram, make it possible for the employees to complete their tasks faster and more purposeful. Using an app, employees are informed about the status of their more than 80 connected machines at all times. Upcoming tasks such as maintenance work or subsequent material deliveries are displayed, evaluated and assigned to the employee with the appropriate qualification.

Opening the data treasure chest with Data Analytics

The production process produces a large quantity of data of various types – the most important raw material of Industry 4.0. With Nexeed Data Analytics, this data can be used intelligently to identify new optimization potential. Customers do not have to deal with Data Analytics themselves; this task is entirely up to the Bosch experts. They gain important insights from product, process and machine data, which can be used to achieve improvements regarding quality, cost and delivery performance. Customers receive an individual service from the first data analysis to comprehensive prediction models.

Intralogistics en route to the digital age

Compared to modern production, the intralogistics sector is lagging behind regarding connectivity. Nexeed Intralogistics Execution deals with the three big challenges: keeping an eye on the vehicle fleet, optimizing material storage and designing transport routes dynamically. Information on all intralogistics processes are available in real-time. By unifying relevant data from different sources – for example RFID in the internal supermarket, forklift localisation and inventory information – the solution not only helps logistics specialist with the daily work, but also allows long-term planning.

Seamless transparency throughout the supply chain

These days frequent travellers can easily share information about their whereabouts. With Nexeed Track and Trace, Bosch has developed a logistics solution that enables the freight to record a digital travel diary. The software not only shares the current location, but also regularly sends information about temperature, vibration and humidity to the cloud via wireless sensors and gateways. This way, supply chains can be traced and permanently optimized. The international freight forwarding and logistics company Panalpina makes use of these benefits. They use Nexeed Track and Trace for a transparent supply chain – not only on the road, but also in the air. On the first test route between Germany and the recipient plant in the U.S, each package was equipped with a sensor. It records regularly relevant parameters such as vibrations. At each gateway, for instance when unloading the truck at the terminal or loading the airplane on the runway, data and the location of the time-sensitive goods are transmitted to the cloud. The Panalpina sees whether the goods have been loaded into the airplane and how they are doing.

Understanding Edge Computing

Guest Contributor: Rittal

With the growth of Artificial Intelligence or AI machinery that takes in information, learns and makes decisions, Edge computing will become not only necessary, but mandatory. The need to process data at the source to ensure acceptable performance will continue to grow with AI and AI will only be able to grow as fast as data storage capabilities grow. edge_923x340

 

To ensure acceptable performance of data processing at the source and reduce latency, Edge Computing will become more important. Formerly only used by large corporations, Edge is now being utilized by small to medium businesses that need services such as peer-to-peer networking, mobile signature analysis, mobile data acquisition, and AI. In the case of machinery, this puts Edge Computing outside of a traditional data center environment and the need for small portable data centers with cooling will spread. According to a recent IDC study by 2020, more than 70% of infrastructure-centric partners will become involved in IoT and Edge Deployment.

Rittal continues to lead the world in global enclosure solutions that include all types of environments. From dirty and extreme temperature fluctuations, to typical clean and climate-controlled environments, Rittal has the right solution for you.

Edge Computing Defined

Edge computing houses data processing capability at or near the “edge” of a network. Usually, servers are contained in a micro data center, with as few as one or two enclosures. Data which is mission-critical, such as a system fail, is captured and available in real-time on site. Edge computing is valuable in capturing bandwidth intensive and latency sensitive data for analysis, lowering operating costs and improving energy efficiency. Lower priority data can be sent to the cloud or to a remote data center.

In Edge Computing, client data is processed at the periphery of the network, as close to the source of the originating data as possible. Companies are moving toward edge computing, driven by economics and efficiency. In edge computing architecture, critical data is processed at the point of origin via a server in close proximity to the output, for immediate and easy access. Data which is not as time sensitive is sent to the cloud or a data center for longer term storage, analysis or compliance record keeping.

The practice of edge computing alleviates the load on network resources. By processing data at the source, only the data required for transfer is shifted to a remote data center or cloud. The amount of data transmitted reduces the strain on bandwidth, and by specifying criteria, data can be sorted to provide key analytics at the site and to push non-essential data to the center.

With IoT and the proliferation of smart devices, edge computing becomes particularly valuable when massive data pushes would overload a data center. When monitoring enclosure temperature for example, it is unnecessary to upload data which will only be valuable to the operations manager in real time. If this data has historical value, it can be pushed to a data center at a later time, or when bandwidth is not at a premium. With edge computing, this illustrates one of its major benefits.

Since edge computing reduces response time to milliseconds, adjustments at the site level can be made almost simultaneously. However, the cloud and data centers will not be made obsolete, since the long term storage capacity is still needed.

Although edge reduces latency and improves accessibility, security concerns and configuration architecture must be addressed. With the distributed architecture of an edge security system, points are increased for system attack. Security breaches and infectious malware may be introduced at vulnerable points.

With the configuration of the device, secure default passwords need to be placed on each device, and vigilance applied to the updating of software to avoid infiltration of malware. Even with the potential points of vulnerability, the overwhelming advantage of the decreased latency and the instant data accessibility overwhelming support the use of edge computing to improve efficiency.

Robot Collaborative Operation

Guest contributor: Tom Knauer, Balluff

In previous blogs, we discussed how “Safety Over IO-Link Helps Enable Human-Robot Collaboration” and “Safety & Productivity”. We’ll build on these blogs and dive more deeply into two robot collaborative operating modes: Safety-Rated Monitored Stop (SRMS) and Speed & Separation Monitoring (SSM).

Human-Robot Collaboration

Human-robot collaboration has received a lot of attention in the media, yet there is still confusion about the meaning and benefits of various types of collaboration. In a previous blog we briefly discussed the four collaborative modes defined by the global standard ISO/TS 15066. The most well-known mode is “power & force limiting”, which includes robots made by Universal Robots and Rethink. As the name implies, these robots are designed with limited power and force (and other ergonomic factors) to avoid injury or damage, but they are also slower, less precise and less powerful than traditional robots, reducing their usefulness in many common applications.

Tom-K-Blog-768x267

The safety-rated monitored stop (SRMS) and speed & separation monitoring (SSM) modes are very interesting because they allow larger, more powerful, traditional robots to be used collaboratively — though in a different manner than power & force limited robots. The updated standards allow the creation of a shared workspace for the robot and human and define how they may interact in this space. Both SRMS and SSM require this shared workspace to be monitored using advanced safety sensors and software, which create a restricted space and a safeguarded space. With SRMS, the robot stops before the operator enters the collaborative workspace — this requires a safety sensor to detect the operator. Similarly, in SSM the goal is to control the separation distance between the human and robot, but it can be dynamic, rather than static as in SRMS. The SRMS separation distance can never be less than the protective distance and this requires sensors to verify the separation.

Spaces

The robot’s restricted space is a 3-dimensional area created to limit where the robot can operate. In the past this was done through limit switches, hard stops or sensors such as Balluff’s BNS; now the standards have been updated to allow this to be done in software with internal robot feedback that can dynamically change to adapt to the robot’s programmed operation. The robot controller can now restrict the robot’s motion to a specific envelope and monitor its actual position against its programmed position within this envelope using software tools such as Safe Move or Dual Check Safety.

The safeguarded space is defined and monitored using safety sensors. The robot might know and assure its own safe position within the restricted space, but it doesn’t know whether or not a person or obstruction is in this space, therefore a safeguarded space needs to be created using safety sensors. Advanced sensors not only detect people or obstructions, but can also actively track their position around the robot and send warning or stop signals to the safety controller and robot. Safety laser scanners, 3D safety cameras and other safety sensors can create zones, which can also be dynamically switched depending on the operating state of the robot or machine.

Closely coordinating the restricted space and safeguarded space creates a flexible and highly productive system. The robot can operate in one zone, while an operator loads/unloads in a different zone. The robot sensors monitor the restricted space while the safety sensors monitor the safeguarded space – and when the robot moves to the next phase of operation, these can dynamically switch to new zones. Warning zones can also be defined to cause the robot can slow down if someone starts to approach too closely and then stop if the person comes too close.

Blog_graphic_Safe-space_081718-01

System Linkages

Linking the restricted space and safeguarded space to create an effective, closely coordinated human-robot SSM/SRMS collaborative system requires several elements: a high performance robot and controller with advanced software (e.g. Safe Move), a fieldbus and a variety of built-in and external sensors (standard and safety).

Significant growth in robot collaborative applications utilizing safety-rated monitored stop (SRMS) and speed & separation monitoring (SSM) will occur as robot users strive to improve productivity and safety of traditional robot systems – especially in applications requiring faster speed, higher force and more precision than that offered by power & force limited robots.

Changing the Paradigm from Safety vs. Productivity to Safety & Productivity

Guest Contributor: Tom Knauer, Balluff

In a previous blog, we discussed how “Safety Over IO-Link Helps Enable Human-Robot Collaboration”. It was a fairly narrow discussion of collaborative robot modes and how sensors and networks can make it easier to implement these modes and applications. This new blog takes a broader look at the critical role safety plays in the intersection between the machine and the user.

In the past, the machine guarding philosophy was to completely separate the human from the machine or robot.  Unfortunately, this resulted in the paradigm of “safety vs. productivity” — you either had safety or productivity, but you couldn’t have both. This paradigm is now shifting to “safety & productivity”, driven by a combination of updated standards and new technologies which allow closer human-machine interaction and new modes of collaborative operation.

Tom_Safety1.pngThe typical machine/robot guarding scheme of the past used fences or hard guards to separate the human from the machine.  Doors were controlled with safety interlock switches, which required the machine to stop on access, such as to load/unload parts or to perform maintenance or service, and this reduced productivity.  It was also not 100% effective because workers inside a machine area or work cell might not be detected if another worker restarted the stopped machine.  Other drawbacks included the cost of space, guarding, installation, and difficultly changing the work cell layout once hard guarding had been installed.

We’ve now come to an era when our technology and standards allow improved human access to the machine and robot cell.  We’re starting to think about the human working near or even with the machine/robot. The robot and machinery standards have undergone several changes in recent years and now allow new modes of operation.  These have combined with new safety technologies to create a wave of robot and automation suppliers offering new robots, controllers, safety and other accessories.

Standards
Machine and robot safety standards have undergone rapid change in recent years. Standard IEC 61508, and the related machinery standards EN/ISO 13849-1 and EN/IEC 62061, take a functional approach to safety and define new safety performance levels. This means they focus more on the functions needed to reduce each risk and the level of performance required for each function, and less on selection of safety components. These standards helped define, and made it simpler and more beneficial, to apply safety PLCs and advanced safety components. There have also been developments in standards related to safe motion (61800-5-2) which now allow more flexible modes of motion under closely controlled conditions. And the robot standards (10218, ANSI RIA 15.06, TS15066) have made major advances to allow safety-rated soft axes, space limiting and collaborative modes of operation.

Technology
On the technology side, innovations in sensors, controllers and drives have changed the way humans interact with machines and enabled much closer, more coordinated and safer operation. Advanced sensors, such as safety laser scanners and 3D safety cameras, allow creation of work cells with zones, which makes it possible for an operator to be allowed in one zone while the robot performs tasks in a different zone nearby. Controllers now integrate PLC, safety, motion control and other functions, allowing fast and precise control of the process. And drives/motion systems now operate in various modes which can limit speed, torque, direction, etc. in certain modes or if someone is detected nearby.

Sensors and Networks
The monitoring of these robots, machines and “spaces” requires many standard and safety sensors, both inside and outside the machine or robot. But having a lot of sensors does not necessarily allow the shift from “productivity vs. safety” to “productivity & safety” — this requires a closely coordinated and integrated system, including the ability to monitor and link the “restricted space” and “safeguarded space.” This is where field busses and device-level networks can enable tight integration of devices with the control system. IO-Link masters and Safety Over IO-Link hubs allow the connection of a large number of devices to higher level field busses (ProfiNet/ProfiSafe) with effortless device connection using off-the-shelf, non-shielded cables and connectors.

Balluff offers a wide range of solutions for robot and machine monitoring, including a broad safety device portfolio which includes safety light curtains, safety switches, inductive safety sensors, an emergency stop device and a safety hub. Our sensors and networks support the shift to include safety without sacrificing productivity.

How do I justify an IIoT investment?

Guest contributor: Will Healy III, Balluff

Many engineers and managers I meet with when presenting at conferences on Smart Manufacturing ask some version of the question: “How can we justify the extra cost of Industrial Internet of Things (IIoT)?” or “How do I convince management that we need an Industry 4.0 project?” This is absolutely a fair and tough question that needs to be answered; without buy-in from management and proper budget allocation, you can’t move forward. While an investment in IIoT can deliver major payoffs, the best justification really depends on your boss.

I have seen three strong arguments that can be adapted to a variety of management styles and motivations.

1) Showing a ROI through Reducing Downtime

“Show me the money!” I think everyone has a manager with this expectation. It may seem like a daunting task to calculate or capture this information, but by using a team, knowing your KPIs and applying anecdotal feedback, you can get a good initial picture of the ROI that an IIoT project will bring to the organization. Many people have shared with me that their initial project’s ROI has “funded the next project.” There is a really great article from MetalForming Magazine that discusses how exactly to do this with the tables and forms they used at ODM Tool & Manufacturing.

Will1.jpg

2) Corporate Goals for Productivity and Utilization

We can be successful getting support for a project when we link corporate goals to project goals. Smart Industry publishes a research project each year that investigates trends in the manufacturing space in regards to digital transformation initiatives. This report cites that the three top benefits manufacturers are seeing are: improving worker productivity (3rd 2016), reducing costs (1st 2016) and optimizing asset utilization (2nd 2016). These goals are driving investments and showing actual results for manufacturers both large and small. However, the report also revealed that more than half of manufacturers cite workforce skills-gap issues as their largest roadblock and this is, I believe, why we saw improving worker productivity move to the top spot. We must bring efficiency and effectiveness to the people we have.

Will2.png

3) Your Competitors are Investing in IIoT!

If you have a boss that worries about falling behind, this can be a motivating argument. Control Engineering recently published a study of manufacturers and how they are investing in IIoT technologies. The largest investments are coming with sensors, connectivity and data analytics. But what is most shocking is that on average IIoT budgets are $328,160, with 18% budgeting more than a half-million dollars. If you want to keep up with the rapid pace of change in the global market, an investment in IIoT is a requirement to remain competitive.

If you are looking for support and partnership on your IIoT projects, we are experienced at utilizing IO-Link, smart sensors and RFID to enable Industry 4.0 and Smart Manufacturing projects.

Economical and intelligent: Handling solutions re-conceived

Guest contributor: Andreas Gryglewski, Bosch Rexroth

The market for handling and robotic solutions is highly price-driven, yet still leaves room for disruptive ideas. Bosch Rexroth provides proof of this with an advanced solution package for Cartesian kinematics. It combines an economical industrial controller with state-of-the-art web technology and assured instruction via a standard tablet. The result: minimum investment costs and maximum efficiency – before and during operation.

Manufacturers of handling solutions for loading and unloading face fierce competition. The volume market demands cost-optimized, rugged and user-friendly solutions that optimally fulfill all requirements in terms of accuracy and cycle times. In addition, users expect quick commissioning with as little programming, instruction and training expenditures as possible. A high degree of productivity and flexibility is also required for the operational phase in order to reduce downtime and so that format or process changes can be more quickly implemented.

All of these requirements are addressed by Bosch Rexroth with a particularly economical solution package for Cartesian kinematics that combines a high-performance motion controller with state-of-the-art web technologies and innovative value-added features. The automation experts make the solution package even more economical with an especially clever idea: users can perform the setup and assured teaching-in on any standard commercially available tablet.

Industrial control, web technology, consumer tablets

In its solution package for Cartesian kinematics, Bosch Rexroth combines a powerful motion controller with modern web technologies and innovative value-added features.

The disruptive solution approach for Cartesian handling from Bosch Rexroth is particularly suitable for machinery manufacturers and end users who want to implement flexibly and reliably adaptable pick-and-place tasks in a short time and at a low cost. Examples include the loading and unloading of injection-molded parts, the sorting of workpieces, or a wide range of intralogistics applications. Bosch Rexroth combines its proven industrial controller with a webserver and a bracket for a typical standard tablet, by means of which the user can visualize the connected handling solution and – graphically-supported – program, teach-in and adjust it as needed. The solution package is comprised of other basic components such as compact servo motors and drives for the kinematics movement, as well as a safety controller for connecting to the tablet bracket for safe teaching-in. From a single source, Bosch Rexroth also optionally offers the mechanical equipment, includinglinear axes with a belt or ball-screw drive and grabbers.

The utmost in connectivity and IT security

In its new handling solution, Bosch Rexroth placed special emphasis on the two key properties of i4.0 –connectivity and IT security. While the optional IoT Gateway ensures the horizontal and vertical networking, the security router with a newly developed IoT firewall, which is also optional, guarantees secure communication between the tablet and controller. Consequently, unauthorized persons can neither log into the controller nor can a virus attack the controller or spread throughout a company’s IT network.

Bild_2_21263-1200x800

Thanks to the newly developed solution packages, handling systems from Bosch Rexroth can be more quickly commissioned, easily programmed, and taught most economically using standard tablets.

Easy commissioning without parameterization

One of the numerous unique features is the operating concept for the handling solution: Immediately after a servo motor is connected with a drive, the latter reads out the stored parameter set from the feedback memory and thus already has all the characteristic data of the mechanical equipment. The result: a considerable time savings and prevention of errors during commissioning, because the user no longer has to manually enter up to 70 parameters. When Rexroth mechanical equipment is ordered in the future, the parameters will be stored in the feedback memory of the motor while still in the plant. If the user puts his own mechanical equipment into operation; the associated parameter file can also be stored in the feedback memory and is efficiently read into the drive upon connecting.

Safe teaching-in using a standard tablet

The disruptive character of the new handling solution becomes clear during setup, which can be performed wirelessly with almost any consumer tablet. It is expeditiously fastened in a bracket especially developed by Bosch Rexroth for teaching-in, which can be adjusted to the respective size and securely encloses the mobile device. On the top left is a combination emergency stop and enabling button that makes reliable and comfortable teaching-in possible for the user. While the left hand holds the tablet and can press the red button, the right hand is free for other operational tasks. The visualization and operation of the handling system is web-based and applies the HTML5 standard, hence is independent of the tablet OS. An optional security router with an integrated firewall provides for IT security.

Programming without programming knowledge

Bosch Rexroth also made the process programming, which precedes the teaching-in sequence, as uncomplicated as possible. Because it uses the graphical programming language Google Blockly, as is the case with the tablet, no programming skills in conventional terms are required. In order to move an axis from point A to point B, for example, only the start and end positions need to be specified, and a line to connect them with each other. The grabbers are also opened or closed by means of graphical elements. Thanks to variables, logical expressions and loops, it is possible to easily specify and clearly represent various processes, also complex ones if necessary.

Features for increasing productivity and quality

Positively contributing to the performance of an especially economical operating phase of the new handling solution are its versatile functions and expansion options. These ultimately also afford the user a high degree of flexibility for changes in process or format. For example, the Active vibration damping function, which provides greater product quality in combination with a sensor, or initiates the exact countermovements in the open-loop process in the linear module in order to prevent undesirable vibrations or to move sensitive products. Thus, for instance, the utmost in accuracy can be achieved when loading and unloading using the grabber sparing the mechanical equipment for a longer service life.

Preventive maintenance and IoT integration

Preventive maintenance can also be cost-efficiently realized in combined usage with the optional IoT Gateway. In order to collect data for analysis and evaluation of the service life, the motor decoder can also be used as an intelligent sensor. If the motor revolutions are converted into linear movements, the timing for lubrication intervals or the replacement of components can be derived, for example. Communication standards such as OPC UA can provide for easy integration into customer-specific IoT systems as needed.

Economical in every way

The solution package is especially suited for pick-and-place tasks that must be quickly and flexibly adaptable – such as for the loading and unloading of injection-molded parts, the sorting of workpieces, or for various intralogistics applications.

 

With the new solution package, Bosch Rexroth introduces a fresh impetus into the competitive market for Cartesian handling. Automation expertise, modern web and IoT technologies, and productivity-enhancing features are combined in a rugged and practical solution concept that takes into account current and future market requirements, and which generates disruptive energy. Consequently, machinery manufacturers and end users find quick and very economical way to implement a reliable, efficient and flexible handling solution that can be commissioned, taught, and adapted to current requirements without any significant knowledge of programming and parameterization.

Innovative approaches of the new handling system:

  • A comprehensive economic package comprising industrial controller, servo motor, drives, security zone module and teaching-in bracket for consumer tablets
  • Maximum security through a router with firewall (optional)
  • Minimal total cost of ownership thanks to:
    • Commissioning without the need for parameterization: Drives automatically read stored mechanical parameters when connected with a motor
    • Device-independent visualization and operation (HTML5)
    • Safe teaching-in bracket for consumer tablets
    • Simplified process flow design without programming knowledge, thanks to Google Blockly
  • Added value functions for productivity and quality – for example vibration absorption
  • Prepared for data tracking for preventive maintenance
  • Easy integration into IoT systems through open interfaces such as OPC UA

Innovative automation solutions for additive manufacturing 2.0

Guest contributor: Peter Berens, Bosch Rexroth

Additive manufacturing is a growth market – sales worth tens of billions of euros are expected by 2020. However, innovative automation solutions are needed if this disruptive technology is to achieve a breakthrough and make the leap from prototype construction and toolmaking to industrial mass production.

If machine manufacturers want to achieve the productivity needed for mass production, they need to reduce the amount of manual work involved, the reject rate and the quality assurance outlay and successfully integrate the machines into the production line. Both challenges can be met through high-performance, intelligent and connective automation.

IoT as a key technology

In the factory of the future, AM machines will be connected horizontally and vertically to higher-level and neighboring IT systems. When it comes to the industrial Internet of things, Bosch Rexroth relies on open i4.0 standards such as OPC UA. With full server/client functionality, processes, cycle times and energy consumption can be evaluated in real time and optimized to achieve better productivity and quality. In conjunction with intelligent algorithms in drive and control technology, Bosch Rexroth also carries out predictive maintenance.

3D printing and the factory of the future

Thanks to decentralized intelligence, drive technology without control cabinets and open standards, the next generation of AM machines is ready for the factory of the future. Wireless communication and modular production lines increase flexibility while reducing set-up times. As a result, the factory layout can be geared to current and future requirements. The next logical step is the decentralization of the control system which will then receive its programs as necessary from the cloud.

What the hardware must be capable of

Whether it be metal, plastic or ceramic: the output in the relevant AM procedure depends very much on the performance of the CNC or motion control system. The shorter the cycle times, the more quickly the NC programs run. The higher the performance, the quicker 3D data can be computed on the CNC and process data collected and processed in real time. The MTX CNC system from Rexroth achieves this with a combination of a high-performance dual core processor and decentralized intelligence allowing fast reaction times. As a result, many additional tasks can be performed by the machine. Planning, programming and the commissioning of all system components take place in a standardized manner via IndraWorks Engineering.

Software makes all the difference

In order to be able to control the application of additive materials precisely and to influence it easily with process variables, the control software too must be particularly powerful. The MTX system software includes numerous AM-specific CNC functions for this purpose. These include an intelligent temperature control system and a 3D online simulation with collision recognition which automatically visualizes the construction time, positioning and printing head travel. The standardized G code is supported by any slicer software. Integrated NC encoding systems protect manufacturer-specific know-how.

Digitizing the workflow

Another key development area is the digitization of the workflow with typical tasks such as print configuration, job management, machine monitoring including online process modification or controlling intralogistics. Because this is not possible without interfaces to the software programs involved (e.g. CAD/CAM systems or simulation solutions), the MTX CNC system has an open system architecture and the Open Core Interface. As a result, machine operators can easily integrate their workflows. In a pre-production context, there are numerous benefits including material simulations or the certification of quality-related parameters. The CNC system thus fits seamlessly into simulation environments as “hardware in the loop”.

Industrial 3D printing in practice

Norsk Titanium AS demonstrates just how efficient industrial 3D printing can be. The world’s leading provider of additive manufacturing technologies for aerospace-grade titanium established the first additive production facility on an industrial scale. In its Rapid Plasma Deposition™ machines, an MTX system controls not only plasma burners but also ten servo axes for producing components and conveying or handling the titanium wire. The MTX system also takes care of process optimization in real time by evaluating sensors and calculating correction values. Bosch Rexroth contributed to the partnership through the experience that it gained during more than 100 group AM projects along with various system components such as drive controllers, supply units, motors and linear systems including the IMS high-precision integrated measuring system.

The German machine tool manufacturer Weisser presented its Weisser additive manufacturing exhibit for the first time at the EMO 2017 and the Metav 2018. Equipped with an additive friction welding unit (AFW), it allows fine layers of metal to be deposited on metal materials and then precision-machined using metal-cutting techniques. As a result, the final contour is maintained with minimal material use. This technology too benefits from the MTX CNC system whose user interface can be integrated seamlessly into the multi-touch operating panel thanks to the open architecture.

The future will be even simpler

With high-performance and high-connectivity automation solutions, industrial 3D printers will be fast and reliable enough for use in mass production. Open interfaces will help to digitize workflows. IoT connectivity is paving the way for the factory of the future. At the same time, experienced system partners such as Bosch Rexroth who provide not only engineering and application support but also complementary technologies such as decentralized drive or linear technology with integrated sensor systems can help manufacturers to acquire the necessary know-how.
