Measuring Changes In Dimensions Of Turbine Blades

Mechanical fixture and electronic gauge probe surface before and after fabrication processes. Assembly of commercially available devices measures changes in dimensions of irregularly shaped part. Turbine blade clamped on rotary table touched by probe of electronic depth gauge. Positioned by micrometers of three-axis translation stage, probe just touches blade. Assembly developed specifically to measure thickness of material added to or removed from surface of turbine blade during fabrication processes.
