3、measuringofenginebladeprofilewithwhitelightopticalprobeGAO Jikun(AECC Shenyang Engine Research Institute, Shenyang 110015, China)Abstract: In order to solve the problem of low efficiency in the aero-engine blades measurement by contactcoordinate measuring machine, more efficient and ac
4、curate measuring methods are needed. The authorconducted a experiment in which the optical probe method was used to measure the blades as a contrast group.Parameters of different blade profiles were assessed. The influence of various error factors on the measurementresults was analyzed
5、 and the uncertainty of the blade profile measurement in optical probe method wasevaluated and compared with the measurement results of contact coordinate measuring machine. In this way,the accuracy of the optical probe method was verified. The experimental results show that measuring
6、theaeroengine blade profile with optical probe is not only accurate but also efficient.Keywords: blade profile; optical probe; profile tolerance; uncertainty; comparative analysis0引 言证。要有效控制叶片加工质量，就需要对叶片型面叶片是发动机重要零部件之一，叶片加工质量进行大量的测量工作，从而对叶片型面检测精度与直接影响到发动机的性能、寿命及安全性。由于叶检测效率提出了更高的要求。目前，在
