Wall-thickness mastering of computer-assisted gages
An alternate method of gage mastering (set up) and a device to verify the accuracy of wall thickness measurements were developed. These are used with computer-assisted gages that measure the contour and wall thickness of metal or plastic parts. A computer program was created to allow a gage to be mastered with a gage master certified directly in wall thickness instead of inner and outer contour as was done previously. This method limits the error possibility to the uncertainty of the master's wall thickness rather than its contours. A universal wall thickness verifier device was designed and used with a gage to resolve a discrepancy between two different certifications of the same master.
