Thread Pitch
Enter the distance from one thread to the next. Choose Thread per inch (TPI) or Inches per thread (IPT)—if you are using metric, Millimeters per thread (MPT) or Threads per Millimeter (TPM). Inches per thread is calculated as 1 / number of threads per inch.
The default value is IPT (MPT if metric), since the pitch is always stored this way in the INC record.
Depth Of Thread
Specify the distance from the major radius of the thread to minor radius. (Do not use the thread diameter.) The default value is calculated from the thread pitch. If you change the thread pitch, the depth will be re-calculated and changed also.
First Cut Depth
This is the initial material removal amount per side.
Minimum Cut Depth
Indicate the minimum amount of material to remove for any pass.
Infeed Angle
Enter the angle for the infeed move. The angle is measured from vertical.
Retract Angle
Enter the angle for the retract move. The angle is measured from vertical.
Retract Clearance
Enter the distance above the top of the thread to retract to, before positioning to the next pass. This move is made at the retract angle.
Starts
Enter the number of starts for the thread.
Spring Passes
Indicate the number of times the final finish pass is cut. The final finish pass can be repeated to remove material that may be left due to part and/or tool deflection.
