ABSTRACT:
Method (FIGS. 4A through 4C) and system (FIG. 3) are disclosed for automatically calibrating a coordinate measuring machine (CMM) (10). The system guides an operator through instrument set-up and data collection procedures. The system automatically converts the collected data into error compensation or axis correction data which represents 21 different geometry errors (i.e. pitch, yaw, roll etc.) of the CMM (10). The error compensation data is then transferred to a CMM measurement processor (36) for subsequent use by the CMM (10) during operation thereof to thereby compensate the CMM (10) for its entire measuring volume (102).
