3.2.2 Incremental dimensions (G91, X=IC)
Function
With the G91 command or the non-modal statement IC, you determine the descriptive
system for approaching individual axes from setpoints in incremental dimensions.
You program how far the tool is to travel.
Programming
G91
Or
X=IC(...) Y=IC(...) Z=IC(...)
Parameters
G91
Relative incremental dimensioning
X Y Z
Axis identifiers of the axes to be traversed
=IC
Incremental dimensions non-modally effective
Example of milling
The dimensions refer to the last point approached.
The circle center point coordinates of the circle interpolation are stated non-modally in
absolute coordinates, since as default the circle center point is independent of G91.
For entering the circle center point coordinates I and J see circle interpolation G2/G3.
