Company spotlight Complete planning and programming on a virtual machine
Tebis's advanced simulation technology enables a detailed representation of the actual manufacturing environment in the virtual world.
Reiner Schmidt, head of Product Management at Tebis, explains: “In times of digitisation and Industry 4.0, the topic of automation is becoming increasingly important, also in the die, mould and mechanical engineering sectors. Anyone wanting to be successful here has to be very well aware of and master three factors: the manufacturing environment, manufacturing knowledge and order processing. With our end-to-end simulation solution, we give users the ideal basis for their first steps on the path to digitisation – and this can be flexibly adapted to the requirements of the day.“
Automation in mould and die manufacturing and mechanical engineering
Modern manufacturing processes are highly complex. First, there is the pure “hardware”, in other words, the machines, tools, clamping devices, equipment units and tool changers. For machining, it is important to know precisely which parts can be manufactured with which machines and tools as well as how absolute maximum efficiency and freedom from collisions can be achieved. And finally, all orders must be precisely controllable on the higher level – both within one's own company as well as at the suppliers. Only in this way can all resources be used optimally.
A key characteristic of advanced simulation technologies is that they enable a detailed representation of the actual manufacturing environment in the virtual world, with no ifs, ands or buts. All machine types common to the market, from various manufacturers, are stored in the Tebis machine library with their geometrical and kinematic properties. The Tebis tool library contains all the tools that a company works with. Tebis also has a unit library for additional equipment such as jaw chucks or steady rests. The CAD/CAM system also includes virtual clamping devices.
Planning and programming with the virtual machine
Because the virtual world in Tebis is a 1:1 representation of the actual manufacturing environment, the benefits of simulation technology can be fully leveraged, from planning all the way to the shop. For example, potential collisions can be detected and corrected during planning – NC programming uses the appropriate setups, tools and orientations right from the start.
The simulator is fully integrated in the CAD/CAM environment. Simulation and collision checking can thus be performed before postprocessing. The unique Tebis machine technology makes this significantly more convenient, reliable and efficient than simulating the NC code and performing adjustments in the control-specific NC format.
The CNC simulator checks the complete machining scenario: This includes machines, heads, clamping devices, axis and traverse movements and much more. In the shop, the machine operator finds information about blank and part geometries, setups and the tools used. And if the machining operation does have to be modified again at the last minute – for instance if a specific machine is down or if tools have been scrapped – this can be easily done. Changes to technology data such as feed rates or spindle speed, setups or the processing sequence up to and including processing on a different machine can be implemented quickly and easily. A renewed collision check is performed on the toolpaths with a mouse click and the results are output via the integrated postprocessors.
MES for efficient manufacturing management and digital order control
No matter how good the CAD/CAM software is, an integrated MES solution (Manufacturing Execution Solution System) is essential for anyone wanting to apply the principles of Industry 4.0 for completely digital and highly automated planning, implementation and control of their orders. The ProLeiS MES solution is therefore a permanent part of Tebis software development. The manufacturing environment, availability of resources, manufacturing knowledge, manufacturing duration and the results from past projects are stored here. In addition, all order processes, including materials logistics and deadlines, are also stored – not only those for one’s own company, but also for suppliers and service providers.
