The objective of this paper is to develop an efficient fixture for key way milling a gear shaft. The fixture is developed to not only provide or facilitate uniform quality in manufacturing but also to provide a system that eliminates individual marking, positioning and frequent checking. This system makes use of a Modular type of fixture which provides an added advantage interchangeability of parts of the fixture. The clamping position of the fixtures, the kinematic constraint balance and the cutting forces are taken into account for the design of the fixture. Solid Edge is used to design and draft the fixture. In addition, the system provides the manufacturer the feature of doing 2 milling operation without the need to interchange the component after each operation. Isometric Standards are followed in the design of this fixture.
