What is a jig design?

A jig is defined as a manufacturing aid that guides a tool. The term “jig” applies to a device used to guide a cutting tools (usually a drill or reamer). The term “fixture” applies to a device used to hold a workpiece, such as a welding fixture.

What are the significance of jig design in the industry?

What is a jig and a fixtures?

Summary: The Major Difference between Jig and Fixture is that Jig is a type of tool used to control the location or motion of another tool. Whereas Fixture is a support or work holding device used to hold work in place. In metal and woodworking, both jigs and fixtures are essential tools used.

What is a fixture design?

Fixtures are workholding devices designed to hold, locate and support workpieces during manufacturing operations. Fixtures provide a means to reference and align the cutting tool to the workpiece but they do not guide the tool.

What are the design considerations used for designing a jig?

[4] The general factors to be considered when designing jig and fixture are shape, material and state of workpart, pre- machined surface tolerance, type of operations and the machine tools used, workpiece handling, ergonomics and safety considerations.

What is the function of jig bushes?

A drill bushing, also known as a jig bushing, is a tool used in metalworking jigs to guide cutting tools, most commonly drill bits. Other tools that are commonly used in a drill bushing include counterbores, countersinks, and reamers. They are designed to guide, position, and support the cutting tool.

Why do we need jig and fixture?

A jig and fixture are workholding devices used in machining operations as an agent of support. They secure, support or mount a workpiece correctly on the parts of a CNC machine. They are very important since they aid smoother manufacturing operations, productivity among other advantages.

How is jig different from fixtures?

Jig is primarily used to guide the movement of cutter repeatedly at predefined locations on the work, and support and locate the part as well. Fixture is mainly used to secure, support and locate the workpiece and maintain predetermined orientation, not guide the cutter.

What are the fundamental principles of jigs and fixtures design?

Fundamental principles of Jigs and Fixtures design LOCATING POINTS: Good facilities should be provided for locating the work. The article to be machined must be easily inserted and quickly taken out from the jig so that no time is wasted in placing the workpiece in position to perform operations.

What is the difference between a fixture and a jig?

The main purpose of a fixture is to locate and in some cases hold a workpiece during either a machining operation or some other industrial process. A jig differs from a fixture in that a it guides the tool to its correct position in addition to locating and supporting the workpiece.

What is an example of a jig?

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. BORING JIG. FIXTURES. It is a work holding device that holds, supports and locates the workpiece for a specific operation but does not guide the cutting tool.

What materials are jigs and fixtures made of?

MATERIALS USED.  Jigs and Fixtures are made of variety of materials, some of which can be hardened to resist wear.  Materials generally used:  High speed Steel: Cutting tools like drills, reamers and milling cutters.
