Methods of cutting operations

Methods of Cutting operation:

1: Orthogonal Cutting Process:

Orthogonal cutting occurs when the major cutting edge of the tool is presented to the work piece perpendicular to the direction of the feed motion. Orthogonal cutting is shown in figure:

2: Oblique Cutting Process:

Oblique cutting occurs when the major edge of the cutting tool is presented to the work piece at an angle which is not perpendicular to the direction of the feed motion, its diagram show that chips removal are the continuous type.
