Pure Reality with Tebis CAD/CAM

Reliable manufacturing is collision-free manufacturing.  And manufacturing reliably means optimally utilising the machines and accounting for all components with ideal traversing and retract movements.

Over the years Tebis CAD/CAM had been building an enviable reputation for its unique knowledge-based machining technology, which supports database libraries of machine tools, cutting tools, cutting parameters, CNC toolpath templates and machining process templates.

Tebis virtual machine technology supports your machining process at three stages. Planning, machine setup and programming so you can check limits, optimum tool axis angles and understand any fixturing required. Programming with the virtual machine means that as the toolpath is calculated Tebis software understands rotary limits of the machine tool and will not create a toolpath not actually possible in reality. Verification and simulation can then be applied to check for collisions against all aspects of the machine such as all physical parts of the machine, fixturing, and other machined parts.

Planning and programming with the virtual machine
The classic CAM simulation is based on cutter location without post-processed output. This offers a quick kinematic with collision check but it will not check on data format or the post processed data. But with Tebis CAD/CAM renewed collision check is performed on the toolpaths with a mouse click and the results are output via the integrated postprocessors. The machine operator has no need to worry about potential collisions and can focus on the actual tasks. All components are completely checked, even against links from the end of one toolpath to the start of the next and also in the case of multiple setups. All the potential collisions can be detected and corrected during planning – NC machine programming uses the appropriate setups, tools and orientations right from the start.

According to Tebis CAD/CAM, “all machine movements fully correspond to the actual machine movements, and if the programmer is satisfied with the outcome then the simulator will send the NC code to the postprocessor. The postprocessor code is simulated which this means that NC code- based machine simulation guarantees collision- free with efficient manufacturing.” Tebis team describes this as “efficient simulation”, as mentioned above every machining simulation can be examined in detail. The Tebis simulator also gives accurate cycle times which allows for better planning.

The programmer can select whether wants to check and simulate individual machining operations or all of them at once. Tebis team clarifies “you can select the suitable machines, machine heads, clamping devices, shuttle tables, units and tools from your available resources. You define any reference points, the values of which can be imported for the setups in NC programming. And you know how many machining operations are required overall.”

Guaranteed optimal, collision- free and efficient machining is the outcome.  The programmer can decide whether wants to accept or correct detected conflicts based on the application. Your modifications are saved in the toolpath and are included in the post processing output. “The machine run times are determined with high precision. You can also access all macros that have been preconfigured for the loaded machine with Tebis simulation and Virtual machining.”

Finally, Tebis CAD/CAM simulation and the virtual machines help to enable a detailed representation of the actual manufacturing environment in the virtual world. “You can simulate the machining operation directly on your desktop and check for collisions with all components. This enables you to ensure that only completely collision-checked NC programs are sent to the machine,” explains Tebis team. All of this also applies to the set-up of multiple components, which may have been programmed by different users.  The Tebis simulator allows you to set up all parts on a machine bed, or tombstone fixture and link the toolpaths of each component together whilst optimising tool changes and tilt directions.
