A New Test Part for Detecting Processing Accuracy of Five Axis CNC Machine Tools

Abstract

Five axis linkage CNC machine tools, with its high speed, high precision characteristics, are widely used in large aircraft structure part machining. By trial cutting method, "S" test part is a new test part for detecting processing accuracy of five-axis linkage machine tools. Through analysis and simulation, exploring the influencing factors to CNC machine tools processing accuracy and the regular of "S" test part surface errors, surface quality, results show that "S" test part can reflect the processing accuracy of CNC machine tools.
