Geometrical product specification (GPS). Coordinate measuring machines (CMM). Testing the performance of CMMs using single-stylus contacting probing systems

DD ISO/PAS 12868:2009 Geometrical product specification (GPS). Coordinate measuring machines (CMM). Testing the performance of CMMs using single-stylus contacting probing systems

DD ISO/PAS 12868:2009 is a Publicly Available Specification which specifies the acceptance and reverification tests for CMM probing error. It is applicable only to Cartesian CMMs using a single-stylus contacting probing system, discrete-point probing mode, and a spherical or hemispherical stylus.
