Answer 1

Answer:

A multipoint tool can be regarded as a series of two or more cutting parts secured to a common body. The majority of multipoint tool are intended to be rotated and the workpiece is moved in a plane normal (as in milling) or parallel (as in drilling) to the axis of spindle rotation. Although the tool geometry and the resulting part features in multipoint machining are different from those in turning processes, the fundamental aspects of chip formation and cutting energy are very similar.

Answer 2

Answer:

1. Drill is a multi-point cutting tool as it contains more than one cutting edges and all cutting edges simultaneously take part in cutting action during machining.

2. A multi-point cutting tool contains more than two main cutting edges that simultaneously engage in cutting action in a pass. Sometime, cutters with two cutting edges (more than one) are also considered multi-point cutting tools (instead of considering it as a double point cutter).
