Machining revolutions Per Minute formula |
||
| \(\large{ RPM = \frac{ SFM \; \frac{12}{ \pi } }{ d_w } }\) | ||
| Symbol | English | Metric |
| \(\large{ RPM } \) = revolutions per minute | \(\large{\frac{rev}{min}}\) | \(\large{\frac{rev}{min}}\) |
| \(\large{ d_w } \) = diameter of workpiece | \(\large{in}\) | \(\large{mm}\) |
| \(\large{ \pi }\) = Pi | \(\large{3.141 592 653 ...}\) | |
| \(\large{ SFM } \) = surface feet per minute | \(\large{\frac{ft}{min}}\) | \(\large{\frac{m}{min}}\) |
