1. What is the primary function of a die in manufacturing?
a) To hold the workpiece in place
b) To cut raw material to length
c) To shape material into a desired form
d) To cool the tool after machining
Rationale: A die forms or shapes material through pressing, cutting, or
drawing operations in the tool and die process.
2. What type of steel is most commonly used for making dies?
a) Mild steel
b) Carbon steel
c) Tool steel
d) Stainless steel
, Rationale: Tool steels have high hardness and wear resistance, making
them ideal for dies and cutting tools.
3. In die design, what does “clearance” refer to?
a) Space between punch and die
b) Space for material storage
c) Difference between punch size and die opening
d) Gap between ram and bolster
Rationale: Clearance ensures proper shearing without excessive wear
or burr formation.
4. The hardness of a die is typically measured using:
a) Vernier caliper
b) Torque wrench
c) Rockwell hardness tester
d) Micrometer
Rationale: The Rockwell hardness test is a standard method to assess
die and tool hardness.
5. Which machine is primarily used to make precise holes in a die plate?
a) Shaper
b) Grinder
, c) Drill press
d) Lathe
Rationale: A drill press ensures perpendicular and accurate holes
essential for die components.
6. What is the purpose of heat treating a die component?
a) Improve surface finish
b) Reduce weight
c) Increase hardness and wear resistance
d) Enhance electrical conductivity
Rationale: Heat treatment strengthens dies and extends their service
life under stress.
7. Which process uses a spark to remove metal from a hardened die?
a) Milling
b) Turning
c) Electrical Discharge Machining (EDM)
d) Broaching
Rationale: EDM removes metal from hard materials without
mechanical contact, ideal for die cavities.
, 8. The term “press fit” refers to:
a) A loose sliding fit
b) A threaded joint
c) An interference fit between two parts
d) A weld joint
Rationale: Press fits hold parts together by friction due to slight
interference.
9. Which die component guides the punch into the die opening?
a) Die shoe
b) Guide post
c) Stripper plate
d) Punch retainer
Rationale: Guide posts align punch and die accurately to ensure
precision and prevent damage.
10. In machining, a reamer is used to:
a) Start a hole
b) Finish and size a hole accurately
c) Tap internal threads
d) Cut grooves
Rationale: Reamers improve the finish and accuracy of pre-drilled
holes.
