Cutting Speed and Cutting Velocity in Machining - Their ...

Cutting speed is the rotational speed of either workpiece or cutting tool (based on which is rotating). It is measured by the unit—revolution per minute (rpm) and designated by N. For example, cutting speed in turning is 295rpm. In case lathe operations, such as turning, grooving, centre drilling, parting, etc., a cylindrical workpiece is used.

Machining 101: What is Grinding? | Modern Machine Shop

Work speed defines the speed at which a grinding wheel passes over a workpiece or rotates around a center. High work speeds lower the heat retention and reduce the risk of thermal damage. Both high work speeds and reducing the diameter of the wheel result in increased grain depth of cut, performing like a softer grade wheel.

GRINDING FEEDS AND SPEEDS

The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines only, which are designed generally for abrasive machining and require appropriately manufactured grinding wheels.
