Design of the component Abstract - For drilling of different types of holes at different position steering arm, we generally require to change fixture for every different hole. This is time consuming process and requires more material handling. This leads to inaccuracy in the operation. Due to inaccuracy the rejection of the product increases. For reworking of this inaccuracy, machining cost increases. For the same reason we manufactured a fixture, which can be useful for drilling different size of holes at different position on steering arm. Because of this work set up time is reduced & material handling also. In this project we manufactured the fixture in which different locators are located on bottom base to drill the holes on steering arm. Thus there is no need to change the fixture for every different size of hole. As single fixture can be used for different size of holes, cost of fixture is reduced, productivity of the operation is increased and manpower required for manufacturing is reduced.

1.INTRODUCTION In today’s modern and competitive world quality must be very high, beside this we should not forget the rate of production as well as golden mean between the quality and productivity should be achieved. A fixture is a work holding or support device used in a manufacturing industry. This fixture is designed for the machine named VADDIGIRIHYDRAULIC MACHINE. The VADDIGIRI- HYDRAULIC MACHINE improves the productivity, save manufacturing time, increases the production rate and reduces man power requirement. Safety precautions are provided with the VADDIGIRI- HYDRAULIC MACHINE. In our project, we are going to manufacture a fixture which can be used for drilling a straight hole by using hydraulic means. Because of this we are going to reduce manufacturing time as well as accuracy of operation.
