Further information
The control requires the following information in order to calculate the tool paths:
● Tool no. (T...), cutting edge no. (D...)
● Machining direction (G41/G42)
● Working plane (G17/G18/G19)
Tool no. (T...), cutting edge no. (D...)
The distance between tool path and workpiece contour is calculated from the milling cutter
radii or cutting edge radii and the tool point direction parameters.
With a flat D number structure, only the D number has to be programmed.
