Tool offsets

General information about the tool offsets

Workpiece dimensions are programmed directly (e.g. according to the production drawing).
Therefore, tool data such as milling tool diameter, cutting edge position of the turning tool
(counterclockwise/clockwise turning tool) and tool length does not have to be taken into
consideration when creating the program.
The control corrects the travel path
When machining a workpiece, the tool paths are controlled according to the tool geometry
such that the programmed contour can be machined using any tool.
In order that the control can calculate the tool paths, the tool data must be entered in the tool
compensation memory of the control. Only the required tool (
data record (
While the program is being processed, the control fetches the offset data it requires from the
tool compensation memory and corrects the tool path individually for different tools:
