Tool radius compensation
11.2 Approaching and leaving contour (NORM, KONT, KONTC, KONTT)
The associated NC program segment is as follows:
Program code
$TC_DP1[1,1]=121
$TC_DP6[1,1]=10
N10 G1 X0 Y0 Z60 G64 T1 D1 F10000
N20 G41 KONTC X70 Y0 Z0
N30 G2 I-70
N40 G40 G1 X0 Y0 Z60
N50 M30
At the same time as the curvature is being adapted to the circular path of the full circle,
traversing is performed from Z60 to the plane of the circle Z0:
