Tebis present their Special CAD/CAM Trimming Precision Process in Technical Corner
MTDCNC invited Andrew Walters, Application Engineer from Tebis UK into the MTD studio to discussthe Tebis trimming solution: “Tebis utilises a very simple and concise method of the vector manipulation, this allow us to create very accurate toolpaths around the trimming profile, very quickly and very simply.”
Andy explains: “I believe that we are the market leader in the trimming world, most of other CAM providers are using the conventional 5-axis toolpaths.”
Optimise Toolpath Vectors and Tilt Directors Machine safety
Having a variety of tools that can accurately and concisely adjust tool direction means that Tebis has full control of the head of the machine, even during the programming process by way of our virtual machine technology. This is particularly important with a typical asymmetric head configuration on a trimming machine, where a lack of control of which side of the asymmetric head is being used can lead to catastrophic collisions.
Tebis can correct and modify an existing toolpath easily with just the addition of the modified geometry: “Tebis has the facility to import an extra piece of geometry such as a curve, and add this into the toolpath. So we don’t need to modify any other CAD data or even reprogram the operation, just open the toolpath operation and add the extra geometry and Tebis will take care of the rest for you.”
Automation in trimming
Using programming templates Tebis is able to give absolutely consistent tool paths and cutting conditions by predefining the parameters. This way all output programs are using the same stepovers, lead ins/outs and safety clearance.
Full collision avoidance
Andy also explains about the full collision avoidance, which is a unique process that other software companies are not able to do. Tebis safety is critical in all areas of machining including 5-axis. Tebis’ collision avoidance is working in the background at all stages of the programming process. Tebis checks the spindle and machine head, tool holder and cutting tool against the finished component and fixturing. It is also able to control all machine movements, including movements between toolpaths. Therefore, the software is able to have total control over all potential collisions thus, safeguarding the part, tooling and machine tool.
Reverse postprocessing, importing historical programs
Tebis can import old teach and learn programs or even old CAM generated programs. – This allows you to adapt historical programs from an old machine to a new machine and even modify old teach and learn programs for modified components.
Andy clarifies: “Trimming in Tebis is simple, accurate and safe. We can guarantee the toolpaths and safety all the way thought the process.”
