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 specifications of the cutting edge position.
Machining direction (G41/G42)
From this information, the control detects the direction in which the tool path is to be displaced.
Note
A negative correction value has the same significance as a change of offset side (G41 ↔ G42).
Working plane (G17/G18/G19)
