Consistent development

Tebis extends its software with functions for laser hardening and laser weld cladding:

09/28/2017

Tebis AG, the process provider for the development, design and manufacturing of models, molds and components, has extended its CAD/CAM software with laser hardening and laser weld cladding functions. Because the new applications are frequently operated with Tebis robot technology, the process provider has also optimized this: Manufacturers can now use the software to simultaneously operate eight individually configurable axes – making them more flexible.

Laser hardening enables locally limited hardening of complex steel parts and steel castings to a defined depth of up to 1.5 mm. These parts then do not have to be reworked to compensate for any resulting distortion. This enables die and mold manufacturers to increase the strength of trim and coining steels, cutting edges and mold plates and thus the service life of the manufactured dies and molds.

Laser weld cladding can be used to repair areas of workpieces – for example, in die and mold manufacturing. In this process, a laser beam fuses the weld metal and the material to be processed in layers, yielding a strong bond. These areas can then be machined.

Both add-ons include a CAD preparation function and collision checking that support the programmers and their work. 3D beam geometry and integrated tool and technology data management combine to produce NC programs with which robots can perform smoother pivoting movements even for highly complex parts.

Tebis has also overhauled its robot technology and extended it to include eight individually configurable axes with simultaneously integrated traversing and rotary table axes. This enables more flexible use of robot cells. The process provider has also provided additional functions that affect robot poses so that users can prevent undesirable singularities and pivoting movements in the limit switch area.
