Measurement Errors of Coordinate Measuring Machine Produced by Touch Trigger Probe System

Article Preview

Abstract:

In this paper, the authors discuss the influence of touch trigger probe system on CMM measurement performance based on measurement experiment results. A ring gage and a plug gage finished in high accuracy are employed as test pieces and the measurements performed under the conditions of combining different extension bar and approaching speed. Two main types of errors, periodic component and high frequency undulation, are verified. Introduction of the extension bar may significantly aggravate the accuracy and reliability, especially, associated with a comparatively large approaching speed. In addition, from the discussions on the generation mechanism of the periodic error and high-frequency undulation, some worthwhile references to engineering applications are also derived.
