The Validation of CMM Task Specific Measurement Uncertainty Software

Abstract

Historically metrologists have attempted to purchase accurate coordinate measuring machines (CMMs) by specifying small values of standardized performance test results such as those defined by the ASME B89. 4.1 or ISO 10360 standards. These standardized tests typically involve very simple measurands, such as point-to-point length, measured on highly idealized and geometrically simple artifacts such as gauge blocks, step gauges, and ball ...
