Cutting Data & Parameters

Cutting Data Terminology

In the turning operation we can distinguish three		Indicated in meters/min. It refers to
	Vc -
important elements:		the speed at the insert edge removing

Work piece’ s rotation at a determined the material at the periphery of the speed of the spindle, “n” work piece. The cutting speed is
linear movement of the tool at a determined related to the diameter of the feed, “f” work piece.
Cut depth, a Defined in mm/rev and it is the

p F - distance covered by the tool during every rotation of the work

n aa piece. “f”- refers to the distance

pp covered by the tool in a one minute, Diam.Diam. that is the feed vf (mm/min) f -ap - Depth of Cut
