6.17.6 Handle Interruption in Tool Radius Compensation

Special movement described below relates only to the tool radius compensation plane axis. It has no influence on the
other axes.
At time of tool radius compensation (G41, G42):
In incremental mode (G91) - The quantity of deviation equals the distance of interruption.
In absolute mode (G90) - If handle interruption is executed in the block for which tool radius compensation (G41, G42) is
being executed, the proper tool path will return in the succeeding block. This rule applies only when the program
absolute position update is valid during single block running. If program absolute position update is valid during
continuous running, the proper tool path will return at the fourth block after the one where the interruption has been
completed.
If there is no G block existed between the block where the interruption has been completed and the block that contains
the tool radius competition cancel command (G40), the proper tool path will return at the block next to the tool radius
compensation cancel command (G40).
