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 fixtures is to maintain low manufacturing costs and to increase industrial efficiency. Fixtures are taking the place of skilled man in the production factory and making it possible to employ unskilled and semi skilled operators. Their use also ensures the uniformity of finished product, which could not be expected otherwise, because of variation of skill between individuals.
In this project attempts have been made in discussions of design principles and basic consideration while designing. Spending a small amount of money when compared to the cost saved per annum we will have an advantage of recurring years together by using a small milling fixture.
