1.
A toolmaker is fitting a punch into a die set and notices
excessive side clearance causing burr formation on stamped
parts. What should be done first?
A. Increase press speed immediately
B. Inspect punch-to-die alignment and clearance values
C. Reduce lubricant application
D. Increase stock thickness
Answer: B
Rationale: Misalignment or incorrect clearance is a primary
cause of burrs and poor cut quality.


2.
When measuring a precision-ground shaft with a micrometer,
what practice helps ensure the most accurate reading?
A. Tighten spindle aggressively
B. Use the ratchet stop consistently

,C. Measure near machine vibration sources
D. Hold frame with both hands tightly
Answer: B
Rationale: The ratchet provides consistent measuring force
and improves accuracy.


3.
A blueprint specifies a positional tolerance for a hole pattern.
What is the primary purpose of this requirement?
A. Specify surface finish only
B. Control feature location relative to datums
C. Increase hardness requirements
D. Reduce machining time
Answer: B
Rationale: Position tolerance controls allowable variation of
feature location.


4.
During surface grinding, a workpiece develops burn marks
and discoloration. What is the most likely cause?
A. Excessive heat generation during grinding
B. Incorrect blueprint scale

, C. Excessive coolant concentration
D. Insufficient wheel balance weights
Answer: A
Rationale: Grinding burns commonly result from overheating.


5.
Why are gauge blocks commonly used in toolrooms?
A. Material storage
B. Precision dimensional standards
C. Surface coating applications
D. Press lubrication
Answer: B
Rationale: Gauge blocks provide highly accurate dimensional
references.


6.
A die section repeatedly cracks near a sharp internal corner.
Which corrective action is most appropriate?
A. Increase hardness further
B. Add a generous radius to reduce stress concentration
C. Increase production rate
D. Reduce lubrication
Answer: B
