Jig and tool design, commonly referred to as jig and fixture design in manufacturing engineering, involves the creation of specialized work-holding and guiding devices to ensure precise, repeatable production of parts during processes like machining, assembly, welding, or inspection. These tools enhance efficiency by reducing setup time, minimizing errors, and allowing for high-volume production of identical components.

Key Components

1.Jigs: These are custom-built devices that both secure the workpiece in place and guide the cutting or forming tool (e.g., a drill) to exact positions, ensuring features like holes or slots are placed accurately. For instance, a drill jig might include bushings to direct the drill bit.

2.Fixtures: These primarily hold and locate the workpiece securely for operations but do not guide the tool itself, relying on the machine operator or equipment for precision. They are often used in milling or grinding setups.

3.Tools in this context: Broader "tool design" encompasses jigs and fixtures but may also include hand tools, assembly aids, or handling devices integrated into the production workflow.

Design Principles

Effective jig and fixture design emphasizes simplicity, robustness, accuracy, and ergonomics to minimize production steps and maintenance needs. Designers consider factors like material selection (e.g., hardened steel for durability), modularity for interchangeability, and integration into the overall manufacturing process to boost productivity—potentially by up to 5x in some cases. Resources like handbooks (e.g., Jig and Fixture Design by Edward Hoffman) provide detailed guidelines for everything from basic plate jigs to complex box-type tooling.
