Undercut DIN 509 F (H=6)
Parameter:
H: Cut type DIN 509 F (H = 6)
I: Undercut depth
K: Underc. breadth
R: Radius in the undercut corner
P: Trav.dpth
W: Angle – Undercut angle
A: Angle – Trav.angle
BE, BF, BD, BP and BH.

The control uses the diameter to calculate the parameters
that you do not define.
Example: Call G25-Geo DIN 509 F

Undercut DIN 76 (H=7)
Program only FP. All the other values are automatically calculated
from the Thread pitch in the standard table if they are not defined.
Parameter:
H: Cut type DIN 76 (H = 7)
I: Undercut depth
K: Underc. breadth
R: Radius in the undercut corner (default: R = 0.6 * I)
W: Angle – Undercut angle (default: 30°)
FP: Thread pitch
