Side Cutting Edge Angle
It can vary from 0 to 90°. On rising side cutting edge angle, the full length of cutting edge is not in contact with workpiece while the tool enters the cut. The tool takes a little shock load and slowly reaches the full depth of cut without any impact. If side cutting edge angle is 0°, the full length of cutting edge is in touch with workpiece at once and generates severe initial shock. If side cutting edge angle is less, forces on tool will decreases as a result of which less power consumption occurs. Also with raise in side cutting edge angle, surface finishes increases and vice-versa.
