Face thread
The face thread is described by
• Thread diameter, preferentially in X direction and
• Thread lead, preferentially with I.
Otherwise, the procedure is the same as for cylindrical threads.

Taper thread
The taper thread is described by the end point in the longitudinal and facing direction (taper
contour) and the thread lead.
The taper contour is entered in Cartesian coordinates X, Y, Z in absolute or incremental
dimensions - preferentially in the X and Z direction for machining on turning machines.
Allowance must also be made for the run-in and run-out paths, across which the feed is
accelerated or decelerated.
The parameter for the lead is based on the taper angle (calculated from the longitudinal axis
lead angle <45° to the outside of the taper lead angle >45°).
