a. Adjusting the length of stroke.
b. Adjusting the position of the stroke.

13. What is the use of shaper dog in hydraulic shaper mechanism?

It is used to change the position of the flow to facilitate the reciprocating motion.

14. What are the advantages of hydraulic shaper mechanism?

a. The cutting and return speed are partially constant through out the stroke.
b. Infinite number of cutting may be obtained from zero to maximum value and control easier.

15. What are the work holding devices used in shaper.

1. Clamping the vise
2. Clamping on the table
3. Clamped to the angular plate.

16. What are the devices used to hold the work in to the table?

a. T bolt and clamps
b. Stop pins
c. Strip and stop pins

17. What are the different operations performed by using shaper?

1. Horizontal surface , 2. Vertical surface 3. Angular surface , 4. Cutting slot and key ways 5. Irregular surface

Planer Machine Interview Question and Answers

18. What is planer?

The planer like a shaper is a machine tool primarily intended to produce plane and flat surfaces by a single point cutting tools. it is used to machining a large work piece which cannot accommodate by shaper table.

19. What is the difference between shaper and planer?

The fundamental difference between shaper and planer is that in a planer the work which is supported on the table reciprocate and the cross wise and perpendicular movement of the tool but shaper the tool reciprocate cross wise and vertical movement of the table.

20. What are the types of planer?

a. Double housing planer
b. Open side planer
c. Pit planer
d. Edge or plate planer
e. Divided table planer

21. What is open side planer?

The open side planer is having housing at one side which is used to accommodate large work pieces

22. What is the main intention for plate planer?

It is used to squaring and beveling the edges of steel plates used for different pressure vessels.

23. What is divided table planer?

This type of planer has two tables on the bed which may be reciprocated separately or together. It is used to reduce the time for setting the work pieces in the table.

24. What are the parts involved in the planer?

a. Bed b. table c. Tool head d. Cross rail e. Housing or column. F. Driving and feed mechanism.

25. What are the parts involved in tool head?

1. Saddle
2. Swivel base
3. Apron
4. Clapper box
5. Clapper block

26. List the mechanism involved in the planer.

1. Table feed
2. Feeding

27. List the mechanism used to drive the table.

1. Open and cross belt drive
2. Reversible motor
3. Hydraulic

28. What is belt shifter lever?

It is used to shift the cross and open belt from one pulley to other to reverse the direction of the table.

29. List two general methods to drive the rack in planer.

1. Through a train of gearing to bull gear engaging the rack.
2. By a worm mounted on the motor spindle which meshes with the rack at an angle

30. List the advantages of electric drive in planer.

1. There is very little chance of any accident as the net driving arrangement is eliminated.
2. Large number of cutting speed and return speed are available.
3. Control is quick and accurate.

31. List the feed mechanism used in planer.

a. By friction disc, b. By electric drive

32. List the feed involved in the planer.

1. Cross feed, 2. Down feed

33. What are the factors considered to hold the work piece in planer?

1. Work should be rigidly fixed to the table so that it may not be shifted out of its position while cutting activity progresses.
2. Proper clamping should be needed all around the work piece.

34. What are the devices used to clamp the work in planer?

1. By standard clamping
2. By special fixtures

35. List the standard clamping devices used in planer.

1. Heavy duty vice
2. T bolt and clamps
3. Angle plate
