| The direction of chip flow is controlled by which of the following angles?
A. Back rake angle
B. Side rake angle
C. Relief angles
D. Cutting edge angles
Please scroll down to see the correct answer and solution guide.
Right Answer is: A
SOLUTION
Concept:
- Back rake angle controls the direction of chip flow.
- Side rake angle controls the amount of bending of chip in width direction. With the increase in side rake angle the amount of bending of chip in width direction reduces.
- Relief angles control interference and rubbing at the tool workpiece interface.
- Cutting-edge angles affect chip formation tool strength and cutting forces to various degrees.
