See the following illustration for start of the tool radius compensation with G42 as example:
The tool tip goes around the left of the workpiece when the tool runs clockwise using G41; the tool tip goes around the right
of the workpiece when the tool runs counter-clockwise using G42.
Information
As a rule, the block with G41/G42 is followed by the block with the workpiece contour. The contour description, however,
may be interrupted by 5 blocks which lie between them and do not contain any specifications for the contour path in the
plane, e.g. only an M command or infeed motions.
Programming example
N10 T1
N20 G17 D2 F300
; Correction number 2, feed 300 mm/min
N25 X0 Y0
; P0 - starting point
N30 G1 G42 X11 Y11
; Selection right of contour, P1
N31 X20 Y20
; Starting contour, circle or straight line
M30
After the selection, it is also possible to execute blocks that contain infeed motions or M outputs:
N20 G1 G41 X11 Y11
; Selection to the left of the contour
N21 Z20
; Infeed movement
N22 X20 Y20
; Starting contour, circle or straight line
