Cutting speed
The cutting speed is the speed at which a tool blade is guided through the material to be processed along the cut it is performing. It is usually given in metres per minute (m/min). Exceptions to this rule are grinding processes as well as some wood-working processes. The cutting speed during these processes is given in metres per second (m/s). [Wikipedia]
The cutting speed during grinding is calculated based on the following formula:
Vc = cutting speed [m/s]
D = tool diameter [mm]
n = rotational speed [1/min.]
The cutting speed, along with the feed speed have a decisive influence on the processing speed during machining and, thus, the output/production volume per unit of time and the achieved surface finish. As the temperature of the blade increases with the cutting speed, any increase in cutting speed also translates to an increase in tool wear and, therefore, a shorter service life. The selection of the optimum cutting speed during grinding depends primarily on the substance/material to be processed.
For safety reasons, applicable standards mandate that the maximum permissible cutting speed of rotating abrasive tools be equal to the maximum operating speed in most cases.
