Development of methods for improving the accuracy of the milling of the GTE compressor blade airfoil

This article provides a technique for improving the accuracy of the milling of the GTE compressor blade airfoil on S500L machine. For the analysis, machining of the GTE compressor blade airfoil on the S500L with the Sinumerik 840D CNC is done. Сontrol trajectory are created using the Siemens NX CAM system. The measurement of the obtained part is made using the DEA Global Performance 10/7/07 CMM. The obtained measurement results are presented in the form of a dependence of the average deviation from a given size on the measured cross section. The assessment of the results is obtained.
