Jigs In metalworking and woodworking, a jig is a type of custom-made tool used to control the location and/or motion of another tool. A jig's primary purpose is to provide repeatability, accuracy, and interchangeability in the manufacturing of products.[1] A jig is often confused with a fixture; a fixture holds the work in a fixed location. A device that does both functions (holding the work and guiding a tool) is called a jig. Cylindrical Grinding Cylindrical grinding is an abrasive machining process that uses a grinding wheel as the cutting tool. The practice is used in a large and diverse areas of manufacturing and tool making. It can produce very fine finishes and very accurate dimensions. Taper Turning Taper Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helical tool path by moving more or less linearly while the work piece rotates. The tool's axes of movement may be literally a straight line, or they may be along some set of curves or angles, but they are essentially linear (in the nonmathematical sense). Thread Cutting Thread cutting, as compared to thread forming and rolling, is used when full thread depth is required, when the quantity is small, when the blank is not very accurate, when threading up to a shoulder is required, when threading a tapered thread, or when the material is brittle.
