1. Which material is commonly used for cutting tools due to its high hardness
and wear resistance?
A. Aluminum
B. Mild steel
C. High-speed steel
D. Brass
Rationale: High-speed steel maintains hardness at high temperatures and
is ideal for cutting applications.
2. What is the primary purpose of a die in manufacturing?
A. To weld metal pieces
B. To shape or cut material
C. To measure dimensions
D. To polish surfaces
Rationale: Dies are tools designed to shape, form, or cut material into
desired shapes.
3. When using a micrometer, the smallest increment typically measurable is:
A. 0.1 mm
, B. 1 mm
C. 0.01 mm
D. 0.001 mm
Rationale: Standard micrometers measure to 0.01 mm (or 0.001 inch in
imperial), allowing precise measurement.
4. Which of the following is a typical heat treatment for tool steel to improve
hardness?
A. Annealing
B. Normalizing
C. Quenching and tempering
D. Cold working
Rationale: Quenching followed by tempering hardens steel while reducing
brittleness.
5. What is the main difference between a punch and a die?
A. Punch cuts, die shapes
B. Punch shapes, die cuts
C. Punch moves into die to cut material
D. Punch holds material, die moves
Rationale: In a punching operation, the punch forces material into the die
to cut or shape it.
6. A lathe is primarily used for:
A. Milling flat surfaces
B. Drilling holes in plates
C. Turning cylindrical parts
D. Grinding edges
Rationale: Lathes rotate workpieces to create cylindrical shapes and
perform cutting operations.
7. What type of fit allows easy assembly without clearance issues?
A. Clearance fit
B. Interference fit
C. Loose fit
, D. Standard fit
Rationale: Interference fits are tight fits designed to prevent relative
motion between parts.
8. In die making, what is a stripper used for?
A. Cutting metal sheets
B. Removing workpiece from punch
C. Cooling dies
D. Holding dies in place
Rationale: Strippers push or pull the material off the punch after a cutting
operation.
9. Which of these grinding wheels is commonly used for hard steel?
A. Aluminum oxide
B. Silicon carbide
C. Cubic boron nitride (CBN)
D. Emery
Rationale: CBN wheels are extremely hard and ideal for grinding
hardened steels.
10.What is the primary purpose of a jig?
A. To measure angles
B. To heat treat metals
C. To guide tools for precise machining
D. To cool workpieces
Rationale: Jigs ensure consistent and accurate machining by guiding
cutting tools.
11.Which process is used to remove metal with chemical means?
A. Milling
B. Grinding
C. Etching
D. Turning
Rationale: Etching uses acids or chemicals to remove metal in specific
patterns or shapes.
