The purpose of this study is to induce the error analysis method of engine compressor blade surface. The model accuracy is evaluated by comparing the difference between the data model and the CAD model through the UG software. At the same time, the detection of surface fairing is made to evaluate the smooth performance of model. Starting from the angle of blade surface modeling, the error sources is found out, the analysis is made on the reason of error generated, and the blade surface accuracy and smoothness are detected. So for the engineering application, the research method on the error analysis of the engine compressor blade surface in this paper is feasible.
