Verified Answers with Detailed
Rationales 100% Correct Grade A Pass
Guaranteed - A+ Graded
1. A die produces parts with excessive burrs along edges. The most likely cause
is:
A. Excessive lubrication
B. Dull cutting edges
C. High press speed
D. Low material thickness
Answer: B. Dull cutting edges
Rationale: Worn tooling fails to shear cleanly, causing burr formation.
2. Case: A progressive die produces misaligned holes in successive stations.
Likely cause:
A. Incorrect strip feeding
B. Excess coolant
C. High press tonnage
D. Low die clearance
Answer: A. Incorrect strip feeding
Rationale: Misfeed disrupts positioning between stations.
,3. A tool steel is selected for high wear resistance. Which property is most
important?
A. Hardness
B. Ductility
C. Conductivity
D. Elasticity
Answer: A. Hardness
Rationale: Hardness improves resistance to abrasion and wear.
4. A die cracks during operation. Likely cause:
A. Improper heat treatment
B. High lubrication
C. Low press speed
D. Clean material
Answer: A. Improper heat treatment
Rationale: Incorrect hardness/toughness balance leads to cracking.
5. Case: A stamping die produces uneven part thickness. Likely issue:
A. Uneven die clearance
B. Excess coolant
C. Proper alignment
D. Clean surface
Answer: A. Uneven die clearance
Rationale: Clearance variation affects material flow.
6. The primary function of a die set is to:
A. Hold and align die components
B. Increase lubrication
, C. Reduce press speed
D. Improve cooling
Answer: A. Hold and align die components
Rationale: Die sets ensure accurate alignment during operation.
7. A punch breaks frequently during operation. Most likely cause:
A. Excessive load or misalignment
B. Proper lubrication
C. Low press force
D. Clean material
Answer: A. Excessive load or misalignment
Rationale: Overstress or misalignment leads to punch failure.
8. Case: Parts stick to the punch after forming. Likely cause:
A. Insufficient lubrication
B. High die clearance
C. Low press force
D. Clean material
Answer: A. Insufficient lubrication
Rationale: Lubrication reduces friction and sticking.
9. A die produces undersized holes. Likely cause:
A. Punch wear
B. Excess lubrication
C. High press speed
D. Low tonnage
Answer: A. Punch wear
Rationale: Worn punches reduce hole diameter accuracy.
