Machining Calculator

1. Select unit of measure: and operation:

2. Calculate Surface Speed(SFM), RPM or diameter. Diameter Surface Speed RPM

3. Calculate Cutting Feed (in/min or in/tooth). RPM # of Teeth Feed/Tooth Feed/Min

4. Calculate Cycle Time. Length of Cut Feed/Min Time(min) Time(sec)

5. Calculate Metal Removal (in³/min). Depth of Cut Width of Cut
Feed(IPM)
Metal Removal Rate

6. Calculate Horse Power. Metal Removal Rate K-Factors
Machine Efficiency (%) Hp @ Spindle Hp @ Motor
