To reduce the required shearing force on the punch, to accommodate a large component on a smaller capacity punch press, shear is applied. In a blanking operation shear is applied on the

	a.	Die
	b.	Die or punch
	c.	Punch
	d.	Die and punch

The operation to be used to remove the burr produced during the blanking operation is

	a.	Shaving
	b.	Trimming
	c.	Nibbling
	d.	Notching

Jig and Fixture serve similar purpose and therefore either of them can be used interchangeably for any machining operation.

True

False

Cutter setting gauge needs to be provided in the case of  fixtures for holding a part in any machining operation.

True

False

Answer 1

1.) Shear is provided on the die for blanking to reduce the required sheaing force.

2.) The operation to be used to remove the burr produced during the blanking operation is trimming. The trimming operation is the last operation performed, because it cuts away excess or unwanted irregular features from the walls of drawn sheets.

3.) FALSE

Jig is a type of tool used to control the location or motion of another tool. On the other hand, a fixture is a support or work holding device used to hold work in place. They are two separate tools with different functions altogether.

4.) TRUE

Gauges are useful inspection tools to assess the acceptability of a part when compared to a pre-determined specification.
