Cutting Speed and Cutting Velocity in Machining - Their Relationship

The simple answer is—to choose cutting tool material and other machining parameters. Every cutting tool material has a maximum and minimum limit of cutting velocity within which it can perform satisfactorily. For example, an HSS (High Speed Steel) can be used between 15 - 40m/min; whereas a diamond tool can be used between 300 - 500m/min.
