In manufacturing, both jigs and fixtures are tools used to hold and support parts during the machining process, but they serve different functions. A jig and fixture are designed to increase precision and efficiency. A jig is a tool that guides the tool during machining, ensuring consistent hole placement and alignment. On the other hand, a fixture securely holds the workpiece in place without guiding the tool. Both tools reduce human error, enhance productivity, and ensure repeatability in mass production. By using jigs and fixtures, manufacturers can significantly reduce setup time, improve accuracy, and achieve a higher rate of consistency in the production process.
