Common Mistakes in Dimensional Calibration Methods

Description: Mitutoyo America Corporation has a long history of providing world-class calibration services as well as premier educational instruction in calibration methods and techniques. This presentation is based on some of the key issues that have been observed in our popular Hands-On Gage Calibration course over the years. Calibration is all about maintaining quality and establishing traceability for measuring equipment. To achieve these goals, calibration must be a well-engineered search for errors. Economic realities limit the amount of time and testing in calibration, and therefore methods must be chosen wisely to provide the most information with the least amount of work. This presentation leverages the excellent American national standards available in dimensional metrology – the B89 series of standards developed under the auspices of the American Society of Mechanical Engineers (www.asme.org). This presentation has been delivered by Mitutoyo...

CMM-GD&T Measurement Planning

Description: This presentation has been delivered at a number of national and international events, and based on the positive response received, Mitutoyo America Corporation wanted to make it more widely available. Many users of coordinate measuring machines (CMMs) struggle with the measurement of workpieces toleranced in accordance with ASME Y14.5 (GD&T). There is no measurement method dictated by ASME Y14.5, as this standard is for defining product requirements and is not a measurement compliance standard. Users of CMMs must consider a number of business and technical factors when planning a measurement method. This presentation introduces the topic of measurement planning and highlights the American national standard on Dimensional Measurement Planning, ASME B89.7.2. This presentation recommends organizations develop best practices for CMM use, and some examples and topics for consideration are discussed.

NIST Engineering Metrology Toolbox

Description: This link is to the Engineering Metrology Toolbox on the website of NIST where two excellent calculators can be found. One is for calculating the elastic compression of spheres and cylinders at point and line contact which is extremely useful for high precision dimensional measurements. The other is for calculating the index of refraction of air which is needed for interferometric length measurements.
