### RPM calculation WOODWEB

RPM is important to calculate, but also the amount of force you will need in relation to the material. Take into consideration, for example, that a 20hp motor could have 1760 rpm and a 40 hp motor could have the same rpm. Speed is important, but also the force or power.

### Grinding Wheel Safety: Respect The Maximum Speed

In the example mentioned, changing from 6,600 rpm to 7,700 rpm multiplies the speed by 1.167. However, the corresponding centrifugal force would multiply by a factor of 1.167 × 1.167, or 1.36. To take a more extreme example, consider the same wheel with a maximum safe operating speed of 6,600 rpm run on a 5inch right angle grinder at 10,000 rpm.
