Explains the principles of jig and fixture design and their importance in automated and robotic manufacturing.

Jigs and fixtures are critical components in automated manufacturing systems. Fixtures locate and hold workpieces accurately, while jigs additionally guide cutting tools. In robotic and CNC-based production lines, fixtures must be designed to ensure repeatability, positional accuracy, and compatibility with robotic grippers and sensors. Proper application of GD&T, locating principles (3-2-1), and material selection directly affects product quality and cycle time. In Body-in-White (BIW) automation, fixtures play a major role in welding accuracy and dimensional control. Poor fixture design often leads to rework, scrap, and inconsistent assemblies.
