Multi-Point Cutting:

This section discusses the technique for the computation of cutting power in multi-point cutting, namely., in the following two kinds of operations (drilling and milling) only.

Milling

In milling operation, the cutter (rotating tool) has a number of cutting edges (or teeth) each of which eliminate material from the workpiece throughout its rotation. In this procedure, feed is given to the table on which the workpiece is mounted. Milling operations might be classified in two categories depend on the direction of rotation of the milling cutter & direction of feeding the workpiece. They are called as up milling (conventional milling) and down milling (climb milling).
