| Jigs and fixtures are the auxiliary tools often used by manufacturing industry companies. The use of jigs and fixtures applies to large companies and small companies. A disadvantage of jigs and fixtures is the use that is devoted to a workpiece, but when the production of the object has been completed, the jig and fixture become unused items. The weakness can be solved by using multipurpose jig. A multipurpose jig is a jig auxiliary which has several parts to modify in accordance with the item to be manufactured, so the jigs and fixtures do not need to be thoroughly rearranged when new workpieces are to be produced. The functions of the multipurpose jigs still meet all the important aspects of jig and fixture. The design method starts from the clarification of tasks, conceptual design, design calculations, design manifestations, and detaildesign. Furthermore, the manufacturing process is carried out to realize the multipurpose jigs based on the design. After the multipurpose jig has build, several tests were conducted on 3 different specimen types, then analyzed the uniformity of specimens resulting from the use of multipurpose jigs. |
