Abstract
The target of the manufacturing industry is to increase the productivity and accuracy. This is done by reducing the set up time and manual fatigue. Thus quality production can be achieved by the use of effective utilization of resources. For large scale production of different materials a lot of time is wasted in set up of the device and clamping the device. For machining operations that cannot be performed on CNC, manual labour is required. Trial and error method is usually practiced for components which are done manually until the axis of the hole is properly aligned with the axis of the drill. In such a situation a lot of time is being wasted to maintain the accuracy. Eventually it increases the operator’s fatigue. Thus drill jig increases productivity by eliminating individual positioning, marking and frequent checking. The main advantage of the jigs is interchangeability. The need of selective assembly is eliminated. The parts of the jig will fit properly and in the assembly and all similar components are interchangeable. Also a jig reduces the repetitive nature required for drilling holes, because the locating, clamping and guiding of the tool is done by the jig itself. The tool guiding element is used whose chief work is to guide the tool in to the correct position. Hence the requirement of skilled labourer is eliminated.
The project study is about a designing and evaluating of drill jig for manual drilling of holes in Integral Fuel Floor. Three designs were draw and compared in terms of accuracy, precision and also the strength of the jigs to select the best design. This report begins with an introduction of Integral Fuel Floor, a class one component in which the holes are to be made using jigs. Designs were evaluated in terms of stability and accuracy. Three new jigs were designed using Solid Works software. Considering the advantages of jigs and fixtures, a fixture was designed to cater to the needs. Increasing the efficiency and accuracy are the two basic aims of production.
