Ch1- Jigs & overtheroadtruckersdispatch.com | Drill | Production And ManufacturingJigs and Fixtures Instructional objectives This lesson will enable the students i Define Fixture and Jig that aid machining ii Conceive the purposes of use of jigs and fixtures iii State the design considerations for jigs and fixtures iv Illustrate the methods of a locating b supporting and c clamping of blanks d guidance of cutting tools in fixtures and jigs to facilitate machining. It gives industry the machines and special tooling needed for todays high-speed, high-volume production. It does this at a level of quality and economy that will ensure that the cost of the product is competitive. Since no single tool or process can serve all forms of manufacturing, tool design is an ever-changing, growing process of creative problem solving. What are Jigs and Fixtures Jigs and fixtures are productionwork holding devices used to manufacture duplicate parts accurately. Anything used to hold a workpiece in a desired location. Locate parts for precision Repeating process on a series of parts Holding parts for machining, painting, assembly.

It is a production tool made so that it not only locates and holds the work piece but also guides the cutting tool as the operation is performed. Jigs are usually fitted with hardened steel bushings for guiding drills or other cutting tools. A jig is any of a large class of tools in woodworking, metalworking, and some other crafts that help to control the location or motion or both of a tool. Some types of jigs are also called templates or guides. The primary purpose for a jig is for repeatability and exact duplication of a part for reproduction. An example of a jig is when a key is duplicated; the original is used as a jig so the new key can have the same path as the old one. Since the advent of automation and CNC machines, jigs are often not required because the tool path is digitally programmed and stored in memory.
