Orthogonal Contour Approach/Departure

Command	NORM
Cancellation	End of block
Programmable with	G40 G41 G42

The 'NORM' command has the effect that the contour is approached orthogonally when cutter radius compensation is switched on. The actual position of the cutter is irrelevant. When de-selecting, the last segment with active compensation is also left orthogonally.

Sample:

N10 G17 
N20 G01 X0 Y0 Z0 F6000
N30 G42 NORM X100 Y0 D5
N40 X200 
N50 G40 NORM X220 Y0
N60 M30
