Automation and digitization are two sides of the same coin. No DMG MORI innovation demonstrates this better than the new WH Flex concept that offers maximum flexibility and scalable performance for automated handling of workpieces and pallets. 

“No matter what our customers want to do – we go along with it!” With this casual statement Markus Rehm, Managing Director of both DECKEL MAHO Seebach GmbH and the joint venture DMG MORI HEITEC GmbH, expresses in a nutshell the unique character of the new WH Flex concept. Sole constraint: Scalability reaches its limits with nine machines or devices in the system and total workpiece or pallet weights over 500 kg.

However, in view of the target group of SMEs in the metalworking sector, this is indeed a negligible drawback.

Otherwise, within its scope of operation the WH Flex really does offer “modular flexibility without limits for automatic workpiece and pallet handling”, Kai Lenfer, also Managing Director of DMG MORI HEITEC, proudly announces.

WH Flex is a modular building block system offering maximum flexibility and scalable performance for the automatic handling of workpieces and pallets.

DIGITAL TWIN

DIGITAL TWIN

HIGHLIGHTS

  • Digital Twin as cybernetic image of the automation system with virtual controls and interfaces
  • Time and cost saving thanksto development-based product optimization
  • Up to 80 percent faster commissioning due to real-time simulation of all processes and procedures
  • End-to-end connectivity for vertical and horizontal system integration
  • High level of investment security thanks to Digital Twin-aided tendering

Automated turning up to 6-sides and milling in up to 5 axes simultaneously? Deburring, washing, drying, checking? Workpieces and pallets in mixed operation? All no problem at all. Only the raw material and pallets have to be adapted to the gripper stations. All other processes are carried out by the WH Flex system, right through to the finished part.

Automation concept with convincing performance

As a classic example of implementation the EMO exhibit integrates a DMP 70 vertical machining center and a 5-axis DMU 40 eVo center to form a highly flexible manufacturing system for automatic complete machining of a mixed variety of workpieces.

The WH Flex concept is based on an extensive set of building blocks that include a number of standard options. The portfolio includes various storage systems such as racks, paternosters and pallet stations.

These can in turn be combined with different gripper and gripper change systems as well as other options such as SPC-based component removal or positioning, turnover and cleaning stations. The possibility of integrating various applications, for laser marking, for example, or measuring and testing, underscores the customer-oriented solution approach.

“Unique solution offering”

However, it is not simply the modular building block concept that makes the WH Flex a “unique solution offering”, as Markus Rehm, Managing Director of DECKEL MAHO Seebach GmbH and DMG MORI HEITEC GmbH, stresses: “As a one-stop, turnkey partner we supply the high-tech machines together with the automation technology as well as all special customized equipment and components. These include controls, fixtures, the tooling and NC programs – right through to the integrated automation and digital connectivity.” It goes without saying that service, maintenance and replacement parts all come from a single source as well. According to Markus Rehm there are three other factors that contribute to the uniqueness of the overall picture, over and above the end-to-end approach. “Firstly the digital twin, secondly, horizontal and vertical networking and thirdly, the proprietary CELL CONTROLLER, whose operation is not just intuitive but also offers outstanding features for flexible production.”

DIGITAL TWIN – DMG MORI HEITEC

DIGITAL TWIN

The entire WH Flex system is planned, controlled and monitored via an intuitive user interface and intelligent  job management. “So no special knowledge or training is necessary for operation,” says Rehm.

He mentions exemplary features such as grid programming for simple teaching and setup for handling new components or job management for preparing urgent orders.

Modular concept for up to 9 machines

“Apart from the soft features, it is the extensive range of possibilities for workpiece and pallet handling for up to 9 machines via the modular WH Flex system that is so impressive”, adds Kai Lenfert, also Managing Director of DMG MORI HEITEC.

In the same breath he goes on to point out another special feature, the integrated gripper change. This enables the productive handling of both workpieces and pallets in the WH Flex system. In this case it is a KUKA robot that acts as the handling device. Kai Lenfert is convinced: “Our small to medium-sized customers in particular benefit from the future-oriented option for entry into flexible automation that we provide for them with the WH Flex modular building block system, especially as all machines within the system remain fully accessible and the customer can grow with the system.”

Consistent virtualization from the design through to the application

Markus Rehm, too, is optimistic and has high hopes for the DMG MORI Digital Twin: “With the aid of the digital twin – a cybernetic image of the real configuration – the system can be put into virtual operation before actual installation – including real-time simulation of all processes and procedures. This sustainably reduces the costs of engineering, comprehensively boosts the quality of the system and saves up to 80 % of the time that would otherwise be needed for commissioning.”

The user will additionally have the option of testing new workpiece / pallet setups virtually while production is running, adds Kai Lenfert. Especially where SMEs are concerned, this additional benefit could contribute significantly to securing the investment decision.

The technology of “digital twins” was first mentioned at the University of Michigan in 2002. 17 years later, digital representations are regarded as the industrial future. The topic is also high on the agenda at DECKEL MAHO Pfronten – especially in the area of product development and particularly as far as the DMU 340 Gantry is concerned.

The first step on the way to the “Digital Twin” is to create a dynamic model of the machine and equip all of the key components and all dynamically sensitive structural elements of the virtual machine with sensors. A functional likeness that reflects all of the characteristics of its real counterpart comes into being when interaction takes place with the PLC and CNC, which are also virtualized.

The behaviour of the “Digital Twin” can now be simulated, analyzed and evaluated in detail during a wide variety of operational situations. Feedback of the simulated knowledge into the real world then takes place “in the loop” until the optimum result has been achieved. “Valuable knowledge can ultimately only arise from new knowledge using an iterative improvement process such as this”, emphasizes Alfred Geißler.

With the DMU 340, knowledge impressively manifests itself in iron and steel and also in bits and bytes – in reality and also virtually.

In the loop for practical iterative improvement

“However, the digital twin will ‘only’ continue to be applicable while time is being saved and quality is improving in our product development”, emphasizes Alfred Geißler. In this way, the “memory” of the digital twin increases with every simulation of a wide variety of scenarios and requirement profiles and every applied increase in knowledge. Gradually, this learning process is intended to lead to a situation whereby the “Digital Twin” will recognize anomalies from its own experience and therefore be able to provide more specific information for continuous improvement.

Evolution to the “Digital Process Twin”

“In the evolutionary interaction, a Digital Process Twin will finally develop from the Digital Machine Twin”, says Alfred Geißler and explains: “The process twin creates the link between product development and customer added value.”

In this context, Alfred Geißler first refers to the effect on collaborative application development, which has almost become a standard procedure in Pfronten, particularly (but not only) in complex 5-axis machining.

Thanks to the “Digital Process Twin”, in future it will be possible to virtually assemble new machines down to their individual components in Pfronten before delivery to the customer. “According to our experience with the virtually mirrored DMU 340, we are convinced that the time for commissioning at the customer’s premises and the start of production can be reduced dramatically”, says Alfred Geißler.

The mirror image of the twin to the digital factory

He also refers to the clear DMG MORI road map of the way forward, from the clearly desirable added value all the way to new business models. The idea is for it to be possible soon for the customer to holistically evaluate new workpieces from the CAD data alone, says Geißler about the future prospects.

In this way, customers will be able to virtually generate and simulate NC programs in the mirror image of the twin, investigate workholding solutions, test tools, create time studies and (more or less in a digital instant) submit reliable quotes. “In conjunction with ERP and MES systems, it could be done on demand with a fixed delivery date”, stresses Alfred Geißler.

This in turn opens up the new world of the “On Demand” and “As a Service” economy. However, Alfred Geißler also sees major opportunities for the DMG MORI business, particularly in service and especially in the area of predictive maintenance. “Because whoever can simulate the future will always know what to do in the present”, is his concluding summary.
