Quiz Questions

01. The part of the tool on which cutting edge is formed is called nose.

02. If the shear angle is large and the chip-tool contact area is low, then the tool life will be more.

03. To grind brittle materials, a coarse grained grinding wheel is used.

04. The cutting force in down milling is maximum when the tooth begins its cut and reduces to minimum when the tooth leaves the work.

05. An operation of enlarging the end of a hole cylindrically is known as grooving.
