Elements
Undercut type E
This form element defines an undercut type E. TURN PLUS suggests
the parameters based on the diameter (see “Undercut DIN 509 E,
Parameters” on page 686).
Undercut type F
This form element defines an undercut type F. TURN PLUS suggests
the parameters based on the diameter (see “Undercut DIN 509 F,
Parameters” on page 686).
Undercut type G
This form element defines an undercut type G. TURN PLUS suggests
the parameters. You can overwrite the values, if required. The
proposed values are based on the metric ISO thread (DIN 13) that is
found from the diameter.
„ Parameters: see “Undercut DIN 76, Parameters” on page 684
„ Determining the thread pitch: see “Thread pitch” on page 688
