Common CMM Terminology:
When researching the certification or purchase of a CMM, questions may arise involving technical terms and CMM specifications that your company may need to consider. Some of the terms involved in CMM service and calibration are listed below with brief descriptions.
Optical Measuring: This term refers to the use of an optical device or probe to obtain a measurement. Some CMM's utilize optical measuring to acquire precise accurate measurements.
Dimensional Metrology: The science that deals with measurement pertaining to a measure of spatial extent, such as width, height or length. CMM's are involved specifically with dimensional metrology.
Gantry CMM: A CMM can be mounted on a gantry to allow it to move around and probe large, cumbersome objects. Other types include Horizontal CMM's and Vertical CMM's.
CMM Certification: In order to comply with industry standards and become an approved supplier in the aerospace industry, most major manufacturers require that CMM's be calibrated and/or certified.
