ABSTRACT:
A fixturing apparatus for locating, orienting and holding a workpiece during a milling operation, having a workpiece specific mounting provided with means for accurately and reproducibly positioning the workpiece within the fixture. The workpiece specific mounting has a workpiece specific pattern of clamping, vibration dampening and supporting devices to hold the workpiece during the milling operation. Accurate, reproducible location and orientation of successive workpieces of the same geometry on the apparatus for the same milling operations is achieved quickly and positively and vibration and workpiece distortion are minimized during the milling operations.
