## CNC speed calculation

This formula is nothing very special but I had to think some time about it. 😉 For my CNC I need to calculate the speed of the machine in mm/min (seems this is the standart measuring unit at least in metric systems). Here it is:

An example:

– Threadpitch: 0.8mm

– Steps/Revolution: 200 Steps

– Microseconds/Revolution: 1.000 micros

Hope this is correct! 😉
