Select the correct answer using the code given below:

Solution:
QUESTION: 6

Why does crater wear start at some distance from the tool tip?

Solution:

Diffusion play an important role in the development of crater wear at a high speed because temperature in the rake face is much higher than that in the flank surface.

QUESTION: 7

Surface obtained for circular generatix and straight line directrix would be

Solution:
QUESTION: 8

Which of the following indicate better machinability?
1. Smaller shear angle
2. Higher cutting forces
3. Longer tool life
4. Better surface finish

Solution:

Factors which come into play while evaluating the machinability of any metal are:
1. Tool life
2. Form and size of chip and shear angle
3. Cutting forces and power consumption
4. Surface finish
5. Cutting temperature
