In order to enhance CMMs’ accuracy by the method, the basic research on error compensation was concentrated on, which included error source analysis, error modeling and measurement. 21 geometric errors of key errors of CMM were found out error model was established and the measurement method with its principle was introduced. The feasibility of the experiment was validated and it laid the foundation for further error compensation method to enhance CMMs’ accuracy. Keywords: coordinate measuring machine (CMM); geometric error; error modeling; error measurement 2017 近日, 经上海市科委组织专家网上评审、见面会考评等评选程序, 上海第二工业大学获得两项上海市自 然科学基金资助。获得资助的项目分别为工学部陈立飞的“高导热和高稳定的不同维数纳米碳材料协同强 化传热的界面材料构筑及导热特性研究” 、汪玲玲的“Au / 氮掺杂碳纳米管催化剂的制备及光催化选择性氧 化芳香醇研究” 。项目期为3 年, 资助力度为20 万元/项。 万方数据
