Formula for calculating cutting process
The circumferential speed ratio is a very important numerical value in setting the use conditions of the rotary dresser.
In general, the low circumferential speed ratio indicates better surface roughness; in contrast, when the ratio approaches 1 (high), the sharpness is emphasized.

How to Determine Peripheral Speed Ratio
Peripheral speed ratio ＝
Vr [m/min]Rotary dresser peripheral speed
N [min-1]Rotary dresser rotational speed
D [mm]Rotary dresser diameter
Vs [m/min]Grinding wheel peripheral speed
N [min-1]Grinding wheel rotational speed
D [mm]Grinding wheel diameter
Determine peripheral speed ratio
