Fast, safe and automated CAM programming to the finished part with Tebis 4.1 Release 3

Tebis 4.1 is a complete CAD/CAM system which is designed for automated manufacturing. It enables CAD/CAM users to perform tasks in design, manufacturing preparation and NC programming in a single integrated system. With the 3rd release of Tebis 4.1, which has already been launched, the company said it takes yet another decisive step toward greater automation and practical implementation. Many new functions also ensure even faster and safer manufacturing.

Time savings with Tebis 4.1

"Tebis 4.1 saves manufacturing companies a lot of time, from data import to the finished part. With consistent implementation of automation, time savings of up to 85% are feasible," said Torsten Fiedler from Tebis CAM Implementation.

Data preparation – the foundation of automated CAM programming – can be quickly and easily completed using parametric CAD templates. With the click of a mouse, holes can be positioned for clamping systems, tilt directions defined, fill surfaces designed and blanks generated.

In Release 3, changes can be controlled directly and conveniently using user parameters and formulae. The CAD elements are automatically transferred to appropriate CAM templates. The Tebis NCJob technology has also been optimised and simplified. The machine can also be set up virtually in the CAD/CAM system and the quality of the results checked. This greatly reduces the load on the machine operator, which is a tremendous advantage in times of skilled labour shortages.

Tebis states that, depending on the category of part, this approach can be used to achieve time savings of up to 85%. Time savings of over 40% should be possible even when manufacturing complex parts.

Precise results when trimming deep-drawing and bending parts

Tebis 4.1 Release 3 provides a new function specifically for active surface design in die manufacturing that can be used to quickly and easily determine theoretically designed trim edges for flanges in deep-drawing and bending parts. The material thickness of the part and the location of the neutral fiber are accounted for – the result is highly precise, with no manual reworking required.

More efficient finishing and high part quality

Geometries like ribs and grooves with steep flank surfaces, straight bottom surfaces or starting and finishing radii can be machined automatically in 3-axis and Z-constant mode and with a uniform step. This ensures excellent part quality because starting and finishing radii can be machined in a single pass without any lifting movements.

Complete collision control with material removal simulation

Material removal simulation ensures even safer manufacturing and provides yet another strong argument for the verification of toolpaths in the CAD/CAM environment before NC output: The material actually present on the model is reliably accounted for at every point in machining. The check is performed right on the blank, which is updated in real time.

Turning with convenient cutting off of the part

Parts can be cut off from bar stock with a special function for automated machining on lathes or turning-milling centers. The part can be deburred and the bar side turned flat at the same time. The cut off part can be transferred to the second spindle or taken by the part gripper/catcher. All processes are automatically controlled and safely simulated.

Flexibly use special cutters

Combined special tools including multiple cutting edge areas with different diameters can be used very flexibly for mill-drilling and thread-milling of bores and circular pockets. This eliminates the need for tool changes and traverse movements with simultaneous high process safety.

Automatic and interactive for faster programming

Manual changes can be automatically transferred between various machining operations to allow for targeted interactive intervention and to adjust the automated CAM programming more easily.
