Jigs

Definition

Jigs are specialized tools or devices used in manufacturing and metalworking to hold and guide workpieces during the machining process. They enhance precision and repeatability by ensuring that the workpiece is consistently positioned for operations such as drilling, cutting, or welding. This level of accuracy is crucial for early mass production techniques, allowing for uniformity in the final products and optimizing workflow efficiency.
