A jig is a type of tool or device used in woodworking and metalworking to guide the workpiece during operations like cutting, drilling, or shaping. It helps ensure accuracy and repeatability, making it easier for craftsmen to produce consistent results. Jigs can be simple, like a wooden frame, or complex, incorporating various mechanisms to hold and position materials. In addition to traditional uses, jigs are also popular in 3D printing and electronics assembly. They help streamline processes by providing a stable platform for assembling components or creating intricate designs. Overall, jigs enhance efficiency and precision in various manufacturing tasks.
