Interactive Milling Formula Calculator

 

The interactive milling formula calculator works for any case variable in bold. Enter the values on the cells on the equation's left side and click the "Solution" button. The answer will appear in the cell on the right side of the equation.

Legend:

- Workpiece diameter at machining point (in inches)

DOC - Depth of cut (in inches)

SFM - Surface feet per minute

RPM - Revolutions per minute

IPR - Inches per revolution

IPM - Inches per minute

IPT - Inches per tooth

WOC - Width of cut (in inches)

Z - Number of teeth in cuter
