Gleason-M&M Calibration Lab Completes A2LA Assessment
April 9, 2010—
The Gleason-M&M Precision Systems' Calibration Lab has received accreditation to ISO/IEC 17025 following a successful recertification assessment by the American Association for Laboratory Accreditation, A2LA. This is the seventh consecutive year the lab has achieved this certification, and it has not been granted to any other lab for gear and spline measurement, according to Gleason's press release.
"Most of the lab's work involves calibration of master gears and spline gauges," says Edward Lawson, chief metrologies and program leader at Gleason-M&M. "Periodic recertification is important because normal wear and tear on these masters can lead to false rejection of production parts.
The lab also calibrates reference involute, lead and pitch masters that are used worldwide to calibrate and verify gear inspection instruments. The A2LA accreditation includes the Gleason-M&M Precision Field Service organization, which provides calibration services for all makes and models of gear involute profile and lead measuring instruments. Following ISO 18653 methods, this procedure involves estimation of U95 measurement uncertainty as the preferred method for instrument calibration and evaluation. Lawson says that measurement uncertainty methods are essentially equivalent to common SPC methods, except as applied to measurement operations. The resulting calibration report provides data that helps the user understand and give due consideration to the reliability of gear and spline measurements.
Gleason-M&M welcomes visitors to this facility in Suburban Dayton, Ohio. Lawson says, "None of the lab's services are more important than sharing our experiences with customers."
