1. What is the primary purpose of a die in manufacturing?
A. To measure parts
B. To shape or cut material
C. To polish surfaces
D. To assemble components
Answer: B
The die is used to cut, form, or shape material into a desired geometry.
2. Which material is most commonly used for making cutting dies?
A. Aluminum
B. Mild steel
C. Tool steel
D. Brass
,Answer: C
Tool steel provides high hardness and wear resistance needed for
cutting operations.
3. What is clearance in a blanking die?
A. Distance between punches
B. Gap between punch and die
C. Thickness of material
D. Stroke length
Answer: B
Clearance is the intentional gap between punch and die to ensure
proper shearing.
4. Increasing die clearance generally results in:
A. Smoother edges
B. Higher cutting force
C. Rougher edges
D. Reduced burr formation
Answer: C
Larger clearance increases fracture, producing rougher edges.
,5. What type of fit is typically used for dowel pins?
A. Clearance fit
B. Transition fit
C. Interference fit
D. Loose fit
Answer: C
Dowel pins are press-fit for accurate alignment.
6. What is the main function of a jig?
A. Hold cutting tools
B. Guide cutting tools
C. Polish surfaces
D. Measure dimensions
Answer: B
A jig guides the cutting tool to ensure repeatable accuracy.
7. Which instrument is used to measure small internal diameters
accurately?
, A. Vernier caliper
B. Outside micrometer
C. Bore gauge
D. Height gauge
Answer: C
Bore gauges are designed for precise internal measurements.
8. What is the Rockwell hardness test used for?
A. Measuring tensile strength
B. Measuring hardness
C. Measuring surface finish
D. Measuring thickness
Answer: B
Rockwell test determines material hardness by indentation.
9. What is lapping?
A. Rough grinding
B. Precision finishing process
C. Heat treatment
D. Machining operation
