| Abstract: | Performance of coordinate measuring machines (CMMs) is adversely effected by structural vibrations. The effect of input shaping, a method of reducing residual vibration, on the quality of CMM measurements has been investigated. Measurements of a CMM show a reduction of structural deflection when input shaping is used. Additional tests indicate that input shaping improves measurement repeatability over a large range of operating parameters. |
