Clamp:    Clamp is a basic element of workholder.The action of pressing the workpiece against the locating surface and hold it against the forces acting upon it is known as clamping. Basic rules of applying clamping forces: Ø Clamping force should be directed towards the nest or locating surfaces. Ø They should be arranged in such a way that the thrust of cutting tool is at a required distance from the clamp. Ø Clamping forces are to be applied on the heavy and strengthy portion of the workpiece. Ø Clamping device should be designed in such a way that it would act for the specific and the correct work.   The above discussed points of rules of applying the clamping forces should be maintained mandatorily otherwise workpiece on which operation to be performed may collapse.

Definition of Drill Jig: Drill Jig defined as a device which is ensuring that a hole to be reamed, tapped or drilled in a workpiece   will be machine in the proper phase.    In this work place should lighting as soon as possible. Should be large enough for holding.   Eliminates the sharp center’s for operator safety. Mention the Advantages of the Drill Jigs : It make possible to drill room or tap holes at much greater speeds and with greater accuracy. When Drill Jigs are used skill workers no need to operate it. The path of cutting tool control by Drill Jigs. Difference between the Drill Jigs and Fixtures: Drill Jig may be remedy around on the table and is not so fast with machine table. But Fixture always fastened with machine bed. Drill Jigs are physically limited and control the path of cutting tool. But fixtures do not guide by cutting tool generally. Drill Jigs applications is drilling, tapp
