Undercut type F
Parameters
K:
Undercut length
I:
Undercut depth (radius)
R:
Undercut radius (in both corners of the undercut)
P:
transverse depth
W:
Approach angle (undercut angle)
A:

TURN PLUS suggests undercut parameters calculated from the
diameter (see ”
11.1.3 Undercut Parameters DIN 509 F”).
Undercut type G
TURN PLUS proposes the parameter values - but you can overwrite
them. The proposed values are based on the metric ISO thread (DIN
13) that is found from the diameter.
