Jig
A jig is a specialized tool used in manufacturing and metal fabrication to guide tools and hold workpieces in place, ensuring consistent and accurate production. Think of it like a template or guide that helps workers make identical parts over and over without mistakes. Companies use jigs to speed up production, maintain quality standards, and make complex tasks simpler for workers. Similar terms you might see include "fixtures," "templates," or "guides." The main difference between a jig and a fixture is that a jig guides the tool while a fixture only holds the work piece.

Example Interview Questions
Senior Level Questions
Q: How do you approach designing a jig for a new complex manufacturing process?
Expected Answer: A senior designer should discuss analyzing the part requirements, considering production volume, operator safety, ease of use, and cost effectiveness. They should mention creating prototypes, testing, and gathering operator feedback.
Q: How do you ensure jigs maintain accuracy over long production runs?
Expected Answer: Should explain maintenance schedules, wear point inspection, material selection for longevity, and implementation of quality check procedures.
Mid Level Questions
Q: What factors do you consider when selecting materials for jig construction?
Expected Answer: Should discuss durability requirements, cost considerations, weight limitations, and how the material choice affects the final product quality.
Q: How do you document jig designs and maintain records?
Expected Answer: Should explain their experience with design documentation, maintenance records, and any relevant software or systems used to track jig specifications.
Junior Level Questions
Q: What are the basic safety considerations when using jigs?
Expected Answer: Should be able to explain basic safety features like proper clamping, sharp edge protection, and operator safety zones.
Q: What is the difference between a jig and a fixture?
Expected Answer: Should explain that a jig guides the tool and moves with it, while a fixture simply holds the work piece in a fixed position.
