Abstract
A system for finish machining an in-process part having an inaccessible interior cavity, an envelope of excess material to be machined, and a predefined minimum wall thickness includes a fixture for holding the in-process part to be finish machined. Also included is a co-ordinate measuring machine having a ball probe for measuring external co-ordinates of the in-process part and also having a sonic thickness probe for measuring wall thickness of the in-process part at various selected points on the part. A programmed digital computer is operably connected to the co-ordinate measuring machine to receive data regarding the measurements made. Stored in the computer is a model of the part which is to be machined and minimum wall thickness requirements at various points on the part. The computer is further programmed to calculate the optimal position of the final part in relation to its interior cavity such that wall thickness requirements are maximally satisfied over the total part surface.
