Tool offsets
8.8 Tool radius compensation (G40, G41, G42)
Fundamentals
8-28 Programming Manual, 10.2004 Edition, 6FC5 298-7AB00-0BP1
Direction of machining G41, G42
From this information, the control detects the direction, in which the tool path is to be
displaced.
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).
