RPM Functions
MILLPWR includes a built-in RPM calculator that allows you to make RPM calculations in
seconds. It calculates the RPM based upon the tool diameter and surface speed.
If your cursor is in the RPM field of a “Set Tool” step before you open the RPM calculator,
MILLPWR can transfer the result directly into the field for you.
To use the RPM calculator:
• Press the CALC key, then the RPM softkey.
• Enter the diameter of your tool.
• Enter the surface speed for the material and cutter type.
Press the SURFACE SPEED TABLE softkey to view
a list of recommended surface speeds.
• If you need to switch from feet per minute to meters per minute, or vice versa, use the
FEET/MIN and METERS/MIN softkeys.
• Press the ENTER key. MILLPWR will calculate the RPM value.
• If your cursor was in the RPM field of a set tool step before you accessed the RPM
calculator, press the
USE key and MILLPWR will transfer the result directly into the
“RPM” field for you.
