Design of work holding device for machining wheel hubs

Abstract Work holding device plays a significant role in the manufacturing of the component that is custom made for any operation. Over the past decade, there has been an increase in mass production and in turn, it has increased the demand for forged components. Wheel hub is an important component of an automobile. It connects the wheel assembly to the axle and the shaft. It is also responsible for the safety of the vehicle as well as the driver. The work holding is the primary issue of the machining operation to be challenged. The objective of this project describes the detailed definition of work holding devices and identifies several benefits that relate to the use of work holding devices in manufacturing. Some of it includes increase in production rate and cost reduction. Parts manufactured with precision and accuracy eliminates the inspection and quality expenses. It helps CNC or VMC machines perform operations by itself and serves the necessary purpose with minimal errors as there is not much of human interference. Implementing this kind of simple and effective mechanism in manufacturing sector drastically reduces the cost of labour and cycle time, thereby increasing the quantity and quality of production. The forged component already manufactured needs to undergo various operations with respect to its orientation. To perform required operation a special Collet system was designed and manufactured to the respective work holding.
