Solution:
QUESTION: 8

Relief angle on HSS tool usually vary from

Solution:
QUESTION: 9

In planetary milling machine, the work and cutter respectively.

Solution:
QUESTION: 10

Milling operation which produces flat vertical surfaces on both side of a work piece is known as

Solution:

Straddle milling is a special form of Gang milling where only side and face milling cutters are used. In this flat vertical surface is produced on both side of a work piece.

QUESTION: 11

Feed rate in milling operation is expressed as

Solution:
QUESTION: 12

In milling machine, the cutting tool is held in position by

Solution:
QUESTION: 13

In which of the following milling machine, the table can be tilted in a vertical plane by providing a swivel arrangement at the knee

Solution:
QUESTION: 14

In case of straddle milling the number of side milling cutters mounted on arbor is/are

Solution:

When milling operation is performed at two different faces simultaneously. By using two milling cutter is called straddle milling.

QUESTION: 15

In which of the following milling operation cutter is rotated in the same direction of travel of work piece

Solution:
QUESTION: 16

In up milling, the chip thickness is

Solution:

In up milling each tooth of the cutter starts the cut with zero depth of cut, which gradually increases and reaches the maximum value as the tooth leaves the cut.
In up milling chip thickness at the start is zero and increases to the maximum at the end of the cut.

QUESTION: 17

In down milling, the thickness of chip is

Solution:

In down milling the maximum thickness of chip is at the start of the cut and decreases to zero at the end of the cut.

QUESTION: 18

Soft materials can not be economically grinded due to

Solution:

Due to production of long continuous chips in case of soft material, continuous chips forced to enter into the space between the abrasive grains and leads to frequent clogging of wheel.

QUESTION: 19

In the Grinding wheel of A 60 Gr7 B 23, B stand for

Solution:

QUESTION: 20

Which one of the following grinding wheels (with grade, grit and bond) is suitable for cutter grinding?

Solution:
QUESTION: 21

Grinding wheel said to be loaded when the

Solution:
QUESTION: 22

In centre-less grinding, the work piece centre be

Solution:

Centre-less grinding is used for grinding cylindrical workpieces without actual fixing the workpiece.

From the figure, the workpiece centre is above the centre of grinding and regulating wheel.

QUESTION: 23

Force on individual grain of a grinding wheel is proportional to the

Solution:
QUESTION: 24

Which one of the following materials is used as a bonding materials for grinding wheels?

Solution:
QUESTION: 25

Tool life in case of grinding wheel is the time

Solution:
QUESTION: 26

In grinding operation for faster and bulk material removal

Solution:

When material is removed in bulk, coarse grain is used and this is called roughening operation while in case of finishing and super finishing operation fine grain structure is used at high speed.

QUESTION: 27

Grinding wheel is balanced

Solution:
QUESTION: 28

The broaching operation in which the work moves past the stationary tool is called

Solution:

The reciprocation of the broach always involves an un-producting return stroke, which is eliminated in a continuous surface broaching machine. In this the small workpieces are mounted on the broaching fixtures which are in turn fixed to a continuously moving conveyor. Broaches which are normally stationary, are kept above the workpieces. The workpieces are pushed past the stationary broaches by means of the conveyor for cutting. The workpieces can be loaded and unloaded onto the conveyor manually or automatically. These machines are used for mass production.

QUESTION: 29

The broaching operation in which either the work or tool moves across the other, is known as

Solution:
QUESTION: 30

Trepanning operation is performed for

Solution:

Trepanning is used to produce large size hole by removing a disk-shaped piece (core) usually from a flat plate. A hole is produced without reducing all the material removed to chip as is the case in drilling.
