Ans. (b) arbor
2. The process of removing metal by a cutter which is rotated against the direction of travel of the work piece is called – (a) up milling, (b) down milling, (c) face milling, (d) end milling.
Ans. (a) up milling
3. The process of removing metal by a cutter which is rotated in the same direction of travel of the work piece is called – (a) up milling, (b) down milling, (c) face milling, (d) end milling.
Ans. (b) down milling
4. In up milling the thickness of the chip is – (a) minimum at the beginning of the cut & maximum at the end of the cut, (b) maximum at the beginning of the cut & minimum at the end of the cut, (c) uniform throughout the cut, (d) none of these.
Ans. (a) minimum at the beginning of the cut & maximum at the end of the cut.
5. In down milling the thickness of the chip is – (a) minimum at the beginning of the cut & maximum at the end of the cut, (b) maximum at the beginning of the cut & minimum at the end of the cut, (c) uniform throughout the cut, (d) none of these.
Ans. (b) maximum at the beginning of the cut & minimum at the end of the cut.
6. The cutting force per tooth movement of the cutter, in up milling is – (a) zero, (b) maximum, (c) increases from zero to maximum, (d) decreases from maximum to zero.
Ans. (c) increases from zero to maximum.
7. In down milling the cutting force per tooth movement of the cutter, is – (a) zero, (b) maximum, (c) increases from zero to maximum, (d) decreases from maximum to minimum.
Ans. (d) decreases from maximum to minimum.
8. The operation of machining several surfaces of a workpiece is called – (a) profile milling, (b) gang milling, (c) saw milling, (d) helical milling.
Ans. (b) gang milling.
