ABSTRACT:
Axis correction or machine charateristic data is stored (108) in memory (110) within a control or measurement processor (36) of a CMM (10) (FIG. 8). The axis correction data includes error data representing 21 different geometry errors (FIG. 4A through 4C) of the CMM. As position information is required, the measurement processor captures the actual position signal from each machine axis sensor and uses this position signal to locate (112) a set of the axis correction data which describes the machine characteristics at that position. The measurement processor then mathematically combines (114) (FIG. 9) the position signal with the subset of axis correction data to obtain a corrected position signal having a corrected set of cooridinate values which describe the probe position in a true Cartesian coordinate system.
