8.1.4 Change of type of radius compensation while machining
The compensation may be changed from G41 to G42 or vice versa without having to cancel it with
G40. It may be changed in any motion block and even in a motionless one, i.e. without moving the
axes of the plane or by programming the same point twice.
It compensates independently the last movement before the change and the first one after the
change. To change the type of compensation, the different cases are solved according to the
following criteria:
A. The compensated paths cut each other.
The programmed paths are compensated each on its corresponding side. The side change takes
place in the intersection point between both paths.
B. The compensated paths do not cut each other.
An additional section is inserted between the two paths. From the point perpendicular to the first
path at the end point up to the point perpendicular to the second path at the starting point. Both
points are located at a distance R from the programmed path.
Here is a summary of the different cases:
