✦ Synopsis

To meet the accuracy requirements, coordinate measuring machines (CMMs) are generally operated with low acceleration-deceleration profiles to minimize residual vibration. This results in low efficiency and may cause a bottleneck in the production line. In the authors' previous study, two control configurations utilizing the inputshaping technique and feedforward controller were proposed to reduce residual vibrations in single-axis and multiple-axis types of motion. This paper focuses on the evaluation of the proposed methods by implementation on a physical CMM. The dynamics of the machine were identified via experiment. The controller design techniques were presented to give the appreciation of the design steps. The evaluations were done by experiment. It was found that the proposed controller implementation methods reduce the residual vibrations by 68 percent for single-axis motion and 88 percent for multiple-axis motion. The methods allow the use of a higher acceleration profile, which results in higher productivity.
