Cutting speed : It is the distance traveled by work surface related to the cutting edge of Tool

v = πdN / 1000 m / min

Feed (s) : The motion of cutting edge of tool with reference to one revolution of work piece.

Depth of cut (t) : It is measured perpendicular to axis of work piece and in straight turning in one pass.  This can be estimated from the relation

t = ( D - d ) / 2 mm

Undeformed chip (Fc) : The cross sectional area of chip before it is removed from work piece.  it is equal to the product of feed and depth of cut.

Fc = s x t mm2

            All tools have a major and minor cutting edge.  The major cutting edge removes bulk of material.  Where as the minor cutting edge gives good surface finish.
