Tool offsets
8.8 Tool radius compensation (G40, G41, G42)
Fundamentals
350 Programming Manual, 11/2006, 6FC5398-1BP10-2BA0
Note
A negative offset value is the same as a change of offset side (G41, G42).
You can generate equidistant paths with OFFN, e.g., for rough-finishing.
Working plane G17 toG19
From this information, the control detects the plane and therefore the axis directions for
compensation.

The tool radius compensation is performed in the X/Y plane, the tool length compensation is
performed in the Z direction.
Note
On 2-axis machines, the tool radius compensation is only possible in "real" planes, in
general with G18 (see tool length compensation table).
Tool length compensation
The wear parameter assigned to the diameter axis on tool selection can be defined as the
diameter value (MD). This assignment is not automatically altered when the plane is
subsequently changed.
