Elements of Jigs and Fixtures



1: Body:
The jig body is generally made of cost iron by casting process or fabricated by welding together various slabs and bars of mild steel. It may be heat treated to relief the stresses. Body is the most prominent feature of the jig. Its main purpose is to support and house the job.

The various jig body are follows:

Types and Functions of Jigs and Fixtures
JIGS AND FIXTURES
Jigs and fixtures are production-workholding devices
used to manufacture duplicate parts accurately. The
correct relationship and alignment between the cutter,
or other tool, and the workpiece must be maintained.
To do this, a jig or fixture is designed and built to hold,
support, and locate every part to ensure that each is
drilled or machined within the specified limits.
Jigs and fixtures are so closely related that the
terms are sometimes confuse ....etc

Abstract :

The aim of designing this fixture is to reduce the manufacturing cost and improve consistency in dimensions and avoid rejections. The various principles involved in fixture design are discussed. They consist of locating principles, clamping principles, loading and unloading principles, safety aspects etc. The employment of fixtures is an important aspect of workshop engineering for the production of he articles in large quantities with a high degree of accuracy and interchangeability at a competitive cost. The purpose of ....etc
