Introduction to Metal Cutting
Metal cutting is a complex process that involves the interaction of several factors, including tool geometry, cutting conditions, workpiece material, and machine tool capabilities. The process can be broadly classified into two categories: orthogonal cutting and oblique cutting. Orthogonal cutting involves cutting with a tool that has a straight cutting edge, perpendicular to the direction of cutting. Oblique cutting, on the other hand, involves cutting with a tool that has an angled cutting edge.
