In Figure 22-C, the insert at the top is set with a zero side cutting edge angle.

Question:

In Figure 22-C, the insert at the top is set with a zero side cutting edge angle. The insert at the bottom is set so that the edge contact length is increased from 0.250 in. depth-of-cut to 0.289 in. The feed was 0.010 ipr.
a. Determine the side cutting edge angle for the offset tool.
b. What is the uncut chip thickness in the offset position?
c. What effect will this have on the forces and the process?
