Faster and safer programming from Tebis

With the latest release of its complete CAD/CAM system, Tebis says it delivers on its promise to enable companies in die, mould and model manufacturing and production machining to manufacture quickly and safely using ultra-modern CAM programming.

The new features offered by Tebis include optimised collision checking that accounts for the machine head and even faster and simpler processing of the most complex geometries.

Reiner Schmid, head of product management at Tebis explains: “As a result of many factors, the situation has been growing increasingly critical for years, with increasing requirements and decreasing margins. Our approach is to give companies a clear advantage with our technological improvements. Tebis makes your manufacturing fast, safe and partially automatic – and that keeps you competitive.”

With 4.1, Release 7, potential collisions can be automatically detected and avoided as early as the CAM calculation. This proceeds smoothly across all milling processes, while fully accounting for the machine head.

The strategies in 2.5D machining and in 5-axis simultaneous avoidance milling have been extended accordingly. In 2.5D machining, milling areas can be optionally reduced or excluded from the machining operation. Tebis determines the correct pivot positions in 5-axis simultaneous avoidance milling.

Because Tebis accounts for both the special kinematics of the real machine as well as the precise geometry of the machine head, collisions with all machining components are already prevented in the virtual CAD/CAM environment and before NC output – reliably, automatically and with corresponding time savings.

In 3-axis finishing, complex geometries can be machined equidistantly with precise and constant stepovers across the entire part in a single operation. This is now even simpler and faster in Tebis 4.1 Release 7. Only up to two arbitrary guide curves need to be selected; the system takes care of the rest automatically.

Extremely high-quality surfaces with no offset are manufactured on the machine – with no need for manual reworking. This function is suitable for all complex parts in which first-class milling programs for 3-axis finishing need to be generated with little effort, for example, for forging dies in forming die manufacturing or for outer surface parts in car body die manufacturing.

Two different modes can be selected in 5-axis simultaneous roughing of pockets and surfaces, depending on the manufacturing situation. In the Dynamic option, the part is machined in five axes normal to the curvature of the surface.

In the Constant option, machining is in three axes parallel to the curvature of the surface. Machining in Constant mode is especially recommended for thin-walled parts with vertical flanks and curved bottom surfaces, like those frequently manufactured in the aerospace industry. Residual stock is reduced to a minimum and can then be cleared in a single operation. This greatly reduces machine run time while maintaining high precision.
