標題: CMM Measurement Strategies [打印本頁] 作者: szcatciliu 時間: 2007-12-18 13:28 標題: CMM Measurement Strategies 這是本人剛從英國NPL網上找到的!關于坐標測量機的資料,英語好的可以下載研究."Measurement Good Practice Guide No. 41".Abstract: This guide covers the selection of the number of measurement points when using Co-ordinate Measuring Machines (CMMs) and gives advice on the compromise between accuracy and speed. It provides guidance on sampling criteria for standard features and advice on measurements that involves projections of features over long distances. It covers cleanliness, part loading/alignment and the effect of temperature,surface finish and geometry on the final result. It also contains information on basic measurement principles, common measurement requirements, CMM software functionality in relation to drawing requirements and good metrology practice when using CMMs with CAD data to inspect parts.
