JIG AND FIXTURE

INTRODUCTION
To reduce production costs, increase efficiency of manufacturing process of a product is very influential, especially by lowering its manufacturing process time. diidentisikasikan manufacturing process time by decreasing setup time and cutting process.

Jigs and fixtures are "tooling aid" that serves to hold and / or directing the work piece so that the process of manufacturing a product can be more efficient. In addition jigs and fixtures can also serve to get high quality product can be maintained as determined quality. With jigs and fixtures, you no longer need your service skills in performing manufacturing operations, in other words workmanship manufacturing process will be easier to get higher product quality or production rate is higher too.

The philosophy of the Group's technology is to benefit from grouping a number of products, both on an equal basis atupun design manufacturing processes on an equal basis. In this study, the similarity process into consideration to improve the efficiency of manufacturing processes.

Thus, the efficiency of the manufacturing process of a product can be increased (to reduce setup time and processing time expression), through the design of jigs and fixtures in the manufacturing process of a group of products.
DEFINITIONS jigs and fixtures
Jigs and fixture tool holder is used for production work piece in order to create a doubling components accurately. And straightness of the true relationship between the cutting tool or other tool, and workpiece should be maintained. To do this then use jigs or fixtures that are designed to hold, support and positioning of each part so that any drilling, machining carried out in accordance with the specification limits.
Jig is defined as a tool / special tool that holds, propped or placed on the component to be machined. This tool is a production tool is made so that he not only placing and holding the workpiece but also to direct the cutting tool when the current operation. Jigs are usually equippedwith hard steel bushing to guide the eye auger / drill (drill) or other cutting tools. Basically, small jigs are not not used bolt / clamp mounted on the table auger (drill press table). Yet for over 0.25 inches in diameter drilling, jigs usually need to be installed with full force on the table.
Fixture is a place of production equipment, holding and supporting

workpiece firmly so that the necessary engineering work to be done. Measuring block or feeler gauge is used in fixtures for reference / setting cutting tools to the workpiece. Fixture must be mounted fixed to the machine table where the workpiece is placed
