NOCTI Manufacturing and Production Processes 1 — Questions and Answers
Question 1: Which type of manufacturing process produces items one at a time to unique customer specifications?
- Mass production
- Job production (Correct answer)
- Batch production
- Continuous flow
Correct answer: Job production
Job production creates individual, custom items built to specific customer requirements.
Question 2: What does the term 'tolerance' mean in a manufacturing context?
- The maximum temperature a material can withstand
- The acceptable range of variation in a dimension (Correct answer)
- The time allowed to complete a task
- The cost limit for a production run
Correct answer: The acceptable range of variation in a dimension
Tolerance defines the permissible upper and lower limits of a measurement so parts fit and function correctly.
Question 3: In a lean manufacturing system, what is 'waste' (muda) primarily defined as?
- Scrap metal from machining
- Any activity that does not add value for the customer (Correct answer)
- Excess inventory over 30 days
- Energy used during production
Correct answer: Any activity that does not add value for the customer
Lean manufacturing defines waste as any step or resource that consumes time or cost without creating customer value.
Question 4: What is the purpose of a Bill of Materials (BOM)?
- To list all employees on a shift
- To record machine maintenance schedules
- To itemize all components and quantities needed to manufacture a product (Correct answer)
- To document customer complaints
Correct answer: To itemize all components and quantities needed to manufacture a product
A BOM is a structured list of raw materials, components, and subassemblies required to produce a finished product.
Question 5: Which quality control tool uses a graphical representation of a process to identify bottlenecks?
- Pareto chart
- Fishbone diagram
- Flowchart (Correct answer)
- Scatter plot
Correct answer: Flowchart
A flowchart maps each step of a process sequentially, making it easier to spot inefficiencies and bottlenecks.
Question 6: What does CNC stand for in manufacturing?
- Computer Numerical Control (Correct answer)
- Centralized Network Configuration
- Composite and Nickel Construction
- Continuous Non-Contact
Correct answer: Computer Numerical Control
CNC (Computer Numerical Control) refers to automated machine tools controlled by programmed computer commands.
