Minimum distance

Depending on the tool head geometry, the tool head may collide with the surface when the tool is inclined. As a result, it may be preferable for the tool head not to undershoot a minimum distance (maximum inclination). When the minimum distance is reached, the tool is virtually extended if it is inclined further so that the tool head remains at a constant height and the specified inclination angle can still be maintained.

The tool is virtually extended automatically by monitoring the minimum distance. Therefore, this method is particularly suited for certain types of machining (laser, waterjet, plasma/autogenous cutting). The change in tool length is displayed on the PLC interface (Virtual tool length) in order to adjust the process (e.g. laser focus point) as required.
