A method for integrating a measurement device for use in measuring a machine component includes providing a coordinate measuring machine (CMM) and combining eddy current (EC) capabilities and CMM capabilities to form an inspection probe. The method further includes installing the inspection probe on the CMM so that the inspection probe measures external boundaries of the machine component with the CMM capabilities and substantially simultaneously measures at least one of internal boundaries, internal defects, surface defects, and material properties of the machine component with the EC capabilities, which are directly linked to actual component dimensional information provided by CMM. The inspection data can be simultaneously linked to and/or displayed with a CAD model to enable a direct comparison between the inspection data and the nominal requirements specified on the CAD model.

An edge contouring system for removing burrs from edges of precision parts. The system includes an industrial robot for moving a special piloted deburring tool along the part edges. A compliance device applies a constant force on the deburring tool to keep it in contact with the part edge, yet permits movement of the tool in a direction normal to the part surface to accommodate for irregularities in the part geometry. A pilot integral with the deburring tool limits penetration of the tool into the part edge.

A consolidated metal-ceramic composite comprises a first phase of particles of aluminum oxide or a solid solution based on aluminum oxide uniformly distributed in a second matrix phase wherein the second matrix phase is non-reactive with aluminum oxide and contains a sufficient amount of titanium carbide at the interface between the first and second phase to prevent a chemical reaction at the interface during consolidation at the liquidus temperature and which exhibits good mechanical properties with regard to strength and toughness at high temperatures up to about 1200.degree. C.

The present invention comprises a cutting tool having a cutting tool insert which may be automatically rotationally indexed. The cutting tool includes a shank and an indexable cutting tool insert rotatably connected to the shank. The insert includes a plurality of tips and a side surface therebetween. Indexing means including an index member slidably mounted to the shank are also provided. The index member includes a locking surface and a cam lobe. The indexing means is effective for rotating the insert upon extension of the index member so that the cam lobe pushingly engages the insert, and locking the insert in a stationary cutting position upon retraction of the index member so that the locking surface is securely positioned against the insert side surface. In an exemplary embodiment of the invention, the index member comprises a slider which is translatable only in a direction parallel to a longitudinal axis thereof. The slider also includes a recess disposed between the locking surface and the cam lobe which is effective for accommodating the insert tip as the insert is caused to be rotated by the cam lobe.
