Fixtures and jigs are specialised manufacturing tools used to secure, support, position, and guide workpieces during machining and fabrication operations. These tools are vital for producing accurate, consistent, and interchangeable parts in industries like automotive, aerospace, metalworking, and CNC machining
A jig is a guiding tool used in manufacturing to direct the path of a cutting or drilling tool so that holes and features are placed in the exact required location on a workpiece. It helps improve accuracy and consistency in repeated machining tasks.
A fixture is a holding device used to securely position and support a workpiece during machining or assembly. It does not guide tools —instead it makes sure the workpiece stays rigid in the correct orientation while work is done.
A jig guides the tool, whereas a fixture holds the workpiece. Both improve manufacturing quality and repeatability, but they serve different roles. Jigs control the path of the tool; fixtures control the stability of the part.
