Work holding devices are a crucial part of the component that are custom made for a particular part or situation. Over the past decade, there in increase in mass production and has increased the demand for forged components. Wheel hubs being the major component in an automotive responsible for attaching the wheel. The work holding was the primary issue of the machining operation to be confronted. The objective of this paper describes the detailed definition of work holding devices and also identifies several benefits that are connected with the use of work holding in manufacturing that includes increase in production rate and cost reduction. Interchangeability and accuracy of machining parts which at most eliminates the need for inspection and quality expenses. It also describes the changeover from the traditional job holding technique towards the fixtures that can be controlled through CNC machines or VMC machines itself and serves the necessary purpose with minimal errors as there is not much of interference of human operators. Adapting this kind of simple and effective mechanism in fabrication and manufacturing sector drastically reduces the cost of labor and cycle time, thereby increasing the quantity and quality of production. This fixture assists the forged work piece used for the wheel hubs of an automobile for drilling and tapping at required positions. The forged component already manufactured needs to be drilled as per the drawings with respect to its orientation to perform the mentioned operations. To undergo the operation a special Colette system was designed and manufactured.
