Elements
Undercut DIN 76 (H=7)
Undercut type H (H=8)
If you do not enter W, the angle will be calculated on the basis of K and
R. The end point of the undercut is then located at the “contour
corner.”
Example: Call G25-Geo DIN 76
. . .
N.. G1 Z-15
[longitudinal element]
N.. G25 H7 I1.5 K7
[DIN 76]
N.. G1 X20
[transverse element]
. . .
Parameters
H
Undercut type DIN 76: H=7
I
Undercut depth (radius)
K
Width of undercut
R
Undercut radius in both corners of the undercut (default:
R=0.6*I)
W
Undercut angle (default: 30°)
Example: Call G25-Geo type H
