Chapter 40, Problem 1RQ
What are the two primary functions of a workholding device?
Expert Solution & Answer
To determine
The primary functions of the workholding device.
Answer to Problem 1RQ
The two primary functions of a workholding device are to hold and to locate the workpiece.
Explanation of Solution
The workpiece is hold by workholding device, which is located by cutting tool to perform cutting operation and this result in repeatability and dimensional accuracy, without workholding device repeatability and dimensional accuracy is not possible.
One of the functions of workholding device is to hold the workpiece so that the workpiece stays fixed while machining operation for dimension accuracy, without the workholding device it is difficult to perform machining operation.
The other function of a workholding device is to locate the workpiece with respect to cutting tool for machining operation to be performed correctly, it fixes the workpiece so that cutting tool can move with respect to it and perform the operation.
Conclusion:
Thus, the two primary functions of a workholding device is to hold and locate the workpiece.
