The Knurling Procedure
The tool motion should be programmed much like a drill cycle. The
recommended SFM is between 50 and 200, with tougher and work-hardening
materials trending towards the low end, and easily machinable materials
trending towards the high.
Axial feed rates of .010"/rev and .020"/rev are usually adequate to produce a
quality knurl.
If no prior parts are available to help set size, start with the head open, and
adjust the opening between the dies downward until the dies pinch on a pin
roughly .010 larger than the minor diameter of the knurl you will be rolling.
Run a trial part on an undersized blank prepared per the section entitled "Work
Piece (Blank) Preparation" , and adjust the die opening downwards until proper
pitch diameter size is obtained. Then, adjust the blank size upwards until
proper major diameter and die fill is obtained. Make blank diameter size
changes slowly, as adjustments to the blank are amplified by a factor of 3 on
the finished rolled knurl major diameter.
