What is the difference between Cp and Cpk, and how would you use them to assess a process?

Explain that Cp measures potential capability assuming centered process, while Cpk accounts for centering. Mention that Cpk is preferred for actual performance and values above 1.33 are typically desired.

Explain the concept of takt time and how it helps in balancing a production line.

Define takt time as available production time divided by customer demand. Discuss how it sets the pace and helps identify bottlenecks to balance workstations.

How would you conduct a root cause analysis for a recurring defect on an assembly line?

Describe using a structured approach like 5 Whys or Fishbone diagram, involving cross-functional team, and validating the root cause with data before implementing corrective actions.

What are the key considerations when designing a fixture for a machining operation?

Cover locating principles (3-2-1), clamping forces, accessibility, chip evacuation, and ensuring repeatability and safety.
