9.1.4 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 a G40. It may be changed in any motion
block or even in a motionless one; i.e. without moving the axis of the
plane or by programming the same point twice.
The last movement before the change and the first movement after
the change are compensated independently. To change the type of
compensation, the different cases are solved according to the
following criteria:
A. The compensated paths intersect 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 intersect 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:
