NOCTI Manufacturing and Production Processes 2 — Questions and Answers
Question 1: What is the primary purpose of Statistical Process Control (SPC)?
- To train new employees
- To monitor and control a process using statistical methods (Correct answer)
- To calculate labor costs
- To schedule maintenance tasks
Correct answer: To monitor and control a process using statistical methods
SPC uses statistical methods to monitor production processes and detect variations before defects occur.
Question 2: In manufacturing, what does 'just-in-time' (JIT) inventory mean?
- Ordering materials at the last possible moment
- Receiving materials only when needed to reduce storage costs (Correct answer)
- Rushing orders to meet a deadline
- Stocking large quantities to avoid shortages
Correct answer: Receiving materials only when needed to reduce storage costs
JIT inventory means materials arrive exactly when needed in the production process, minimizing inventory holding costs.
Question 3: Which of the following best describes a 'prototype' in product development?
- The final version of a product ready for sale
- A preliminary model used to test and evaluate a design (Correct answer)
- A technical drawing of a part
- A cost estimate for production
Correct answer: A preliminary model used to test and evaluate a design
A prototype is an early sample or model built to test a concept or design before full-scale production.
Question 4: What is the function of a quality control inspection at the end of a production line?
- To train production workers
- To verify finished products meet specified standards before shipment (Correct answer)
- To calculate production costs
- To assign maintenance schedules
Correct answer: To verify finished products meet specified standards before shipment
End-of-line inspection ensures that completed products conform to quality specifications before reaching customers.
Question 5: Which machine operation removes material by rotating a cutting tool against a stationary workpiece?
- Turning
- Milling (Correct answer)
- Drilling
- Grinding
Correct answer: Milling
Milling uses a rotating multi-point cutter to remove material from a stationary or moving workpiece to create flat or contoured surfaces.
Question 6: In manufacturing, what does 'cycle time' refer to?
- The lifespan of a machine
- The total time required to complete one production cycle (Correct answer)
- The time between scheduled maintenance
- The time a product spends in storage
Correct answer: The total time required to complete one production cycle
Cycle time is the total elapsed time from the start to the completion of a single unit in a production process.
