Machining Spindle Speed
Machining Spindle Speed formula |
||
| \( s_s = s_c \; d \; \pi \) | ||
| Symbol | English | Metric |
| \( s_s \) = spindle speed (RPM) | \(rev\;/\;min\) | \(rev\;/\;min\) |
| \( s_c \) = cutting speed (SFM) | \(ft\;/\;min\) | \(m\;/\;min\) |
| \( \pi \) = Pi | \(3.141 592 653 ...\) | |
| \( d \) = tool diameter | \(in\) | \(mm\) |
