Sawing and Broaching Machines MCQs

Q1 | What is the main advantage of broaching over shaping process?

Use of single point cutting tool which are inexpensive and can be grounded to any shape

Thin or fragile jobs can be conveniently machined because of lower cutting forces

Surfaces with obstruction can also be machined

Removal of the whole material in one stroke

Q2 | For which of the following operations, broaching can be used?

Threading

Grinding

Spline cutting

Increasing the size of the existing hole for a certain length

Q3 | Why push type broaches are made shorter in length?

To reduce machining time

To increase the efficiency

For easy handling of the tool

To avoid buckling

Q4 | Why chip breakers are provided on the broach?

To reduce machining time.

To increase the cutting force by breaking the chips

To reduce the friction between tool surface and the workpiece by breaking the chips

To break up the wide curling chips

Q5 | Why neck section provided in the pull type broaches are made shorter in diameter?

To provide better surface finish

To remove chips easily

To allow failure in case of overloading
