GLEASON-M&M Calibration lab completes A2lA assessment

Mar 31, 2010

Gleason Corporation today announced that its 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.  2010 is the seventh consecutive year the Lab has achieved this accreditation, which has never been granted to any other lab for gear and spline measurement.

According to Edward Lawson, Chief Metrologist and leader of the program at Gleason-M&M, “Most of the Lab’s work involves calibration of master gears and spline gauges.  Periodic recertification is important because normal wear and tear on these masters can lead to false rejection of production parts.”  This lab also calibrates reference involute, lead, and pitch masters that are used throughout the world 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.  No other organization provides this accredited calibration service in the U.S.  Following ISO 18653 methods, this procedure involves estimation of U95 measurement uncertainty as the preferred method for instrument calibration and evaluation.  While many are unfamiliar with this technique, Lawson says that measurement uncertainty methods are essentially equivalent to common SPC methods except as applied to measurement operations.  Data provided in the resulting calibration report helps the user understand and give due consideration to the reliability of their gear and spline measurements.

ISO 9001 and ISO/TS 16949 standards require accredited calibration documents such as those provided by Gleason-M&M Precision Systems to properly establish traceability to NIST.  According to Lawson, certification documents from organizations lacking proper accreditation for their gear and spline measurement work cannot be relied upon to meet these requirements.

Gleason-M&M welcomes visitors to their facility in suburban Dayton, Ohio where the calibration lab is located.  Mr. Lawson, who is also a leader in the development of US and international standards for gear accuracy and gear instrument evaluation, believes their gear lab is truly a “Best Practices” operation.  He says, “None of the lab’s services are more important than sharing our experience with customers.  It’s all part of Gleason’s commitment to being the Total Gear Solutions™ Provider.”
