What is grooving on a lathe?

Groove cutting on CNC lathes is a multi step machining operation. The term grooving usually applies to a process of forming a narrow cavity of a certain depth, on a cylinder, cone, or a face of the part. The groove shape, or at least a significant part of it, will be in the shape of the cutting tool.
