From Confusion to Clarity: Two Decision Rules to Rule Them All
Calibration laboratories must increasingly utilize clear, defensible decision rules to state conformity, as required by ISO/IEC 17025. Although this is required, many people remain confused about how to implement it in practice. There is little reason not to use these decision rules, as the math behind them is straightforward.
Making Sense of Gage R&R Analysis
The term Measurement Systems Analysis (MSA) refers to a collection of experimental and statistical methods designed to evaluate the error introduced by a measurement system, and the resulting usefulness of that system for a particular application. In manufacturing, measurement system quality directly affects decisions about processes, products, and a manufacturer’s ability to meet their customers’ requirements.
The Unbroken Chain of Confidence: Integrating Measurement Traceability, Advanced Uncertainty Management, and Digital Confirmation in CMM Operations
The integrity of dimensional measurement, particularly within the Coordinate Measuring Machine (CMM) discipline, is governed by a stringent framework of international standards designed to ensure comparability, consistency, and absolute confidence in the results.
CMM Volumetric Compensation: A Comprehensive Guide to Calibration, Error Mapping, and Correction
Coordinate Measuring Machines (CMMs) are central to dimensional quality assurance. However, like all physical systems, they are subject to geometric inaccuracies introduced through mechanical wear, assembly tolerances, and environmental conditions. To maintain traceable, high-precision measurements, these machines undergo volumetric compensation—a process that quantifies and mathematically corrects spatial errors across the entire measuring volume.
Difference Between Calibration and Verification
When it comes to in-the-field calibration of video measuring systems and other high-end measuring equipment, companies I talk to often do not realize or understand the difference between verification and calibration.
