1. What is the primary purpose of a die set?
A. Increase machine RPM
B. Guide die components accurately
C. Lubricate cutting tools
D. Apply heat treatment
Answer: B
The die set aligns and guides the upper and lower die shoes for
precision.
2. Which tool is most suitable for measuring inside diameters?
A. Vernier caliper
B. Depth micrometer
C. Telescoping gauge
D. Inside micrometer
Inside micrometers are specifically designed for accurate internal
diameter measurement.
3. What is the typical angle for a standard drill point?
A. 90°
B. 118°
C. 120°
,D. 135°
118° is standard for general-purpose drilling.
4. Which material is commonly used for high-wear die components?
A. Mild steel
B. Aluminum
C. Tool steel
D. Brass
Tool steels offer high hardness and wear resistance.
5. What is the function of a punch in a die?
A. Support the workpiece
B. Shear or form the material
C. Lubricate the sheet
D. Measure thickness
Punches apply the working action such as shearing or forming.
6. The process of removing sharp edges from a part is known as:
A. Facing
B. Tapping
C. Deburring
D. Boring
Deburring eliminates burrs produced during machining.
7. Which device ensures repeatable positioning in a press die?
A. Clamp
B. Stop block
C. Spacer
D. Shim
Stop blocks set consistent shut height.
, 8. Which material property describes resistance to permanent
indentation?
A. Toughness
B. Elasticity
C. Hardness
D. Ductility
Hardness measures resistance to indentation.
9. A go/no-go gauge is primarily used for:
A. Surface finish checks
B. Attribute inspection
C. Dimensional scanning
D. Measuring angles
Go/no-go gauges check if a part passes or fails dimensional limits.
10. Heat treatment that increases hardness by heating and rapid
cooling is:
A. Annealing
B. Tempering
C. Normalizing
D. Quenching
Quenching traps carbon and increases hardness.
11. Which machining process produces the best surface finish?
A. Milling
B. Grinding
C. Drilling
D. Reaming
Grinding produces fine and accurate surfaces.
