Sample Millwright Test Questions and Answers
Mechanical Systems and Components
Question: What is the primary purpose of a bearing in machinery?
Answer: Bearings support rotating shafts and reduce friction between moving parts, enabling smooth operation.
Question: Which type of pulley is used to change the direction of force in a belt drive system?
Answer: A fixed pulley.
Question: How do you calculate the gear ratio between two gears?
Answer: Gear ratio = Number of teeth on driven gear / Number of teeth on driving gear.
Blueprint Reading and Technical Drawings
Question: What does a section view in a blueprint illustrate?
Answer: It shows an internal view of an object by cutting through the part, revealing hidden features.
Question: When reading a mechanical drawing, what does the abbreviation "Ø" signify?
Answer: Diameter of a circular feature.
Question: How are tolerances represented in technical drawings?
Answer: Tolerances are specified as plus/minus deviations from the nominal dimension, often noted after the dimension (e.g., 50 ±0.1 mm).
Installation Procedures
Question: What is the purpose of shimming during machinery installation?
Answer: Shimming is used to precisely align and level equipment to ensure proper operation and reduce wear.
Question: Which tools are commonly used for aligning machinery?
Answer: Dial indicators, laser alignment tools, straightedges, and spirit levels.
Question: Describe the general steps involved in installing a motor onto a baseplate.
Answer:
1. Position the motor on the baseplate.
2. Use shims or leveling devices to align the motor horizontally and vertically.
3. Secure the motor with bolts, tightening gradually in a criss-cross pattern.
4. Verify alignment with precision tools.
5. Connect the motor to the driven equipment.
Maintenance and Troubleshooting
Question: What is the first step in troubleshooting a machine that is overheating?
Answer: Check for proper lubrication, blocked cooling vents, or malfunctioning cooling systems.
Question: How can misalignment affect machinery performance?
Answer: It can cause increased wear, vibration, noise, and eventual failure of components.
Question: What is the purpose of performing a preventive maintenance routine?
Answer: To detect potential issues early, reduce unscheduled downtime, and extend equipment life.
Safety Protocols and Regulations
Question: What is lockout/tagout (LOTO) and why is it important?
Answer: Lockout/tagout is a safety procedure that ensures machinery is properly shut off and cannot be restarted during maintenance, preventing injury.
Question: Which personal protective equipment (PPE) should a millwright wear when working on machinery?
Answer: Safety glasses, gloves, hearing protection, steel-toed boots, and possibly a hard hat.
Question: What are common hazards in a machining environment?
Answer: Moving parts, sharp edges, flying debris, electrical hazards, and high-pressure systems.
