Compensation of CMM geometrical errors by the GEMIL technique: Experimental results

GEMIL (Geometrical Errors by Measurement of Independent Lines) is a technique for compensating geometrical errors of Coordinate Measuring Machines (CMMs), first introduced in [7]. It is intended for industrial application, with a focus on deriving the error components as inexpensively as possible, while still achieving state of the art accuracy. The simulations reported in [7] were validated experimentally with three industrial CMMs in non laboratory conditions, through standard testing according to the ISO 10360-2 [9]. The results prove the effectiveness of the technique and confirm GEMIL as a low cost industrial alternative to existing compensation techniques.
