Abstract:In order to improve the machining quality of spindle blade，45 steel is used as the material to process slender shaft parts with different speed，feed rate and cutting depth of CNC lathe.The dimension accuracy and surface roughness of the parts are detected， and the data are analyzed by normal distribution and single factor contrast test.The results of five groups of experiments and data analysis within the variable levels of factors used in the tests show that the overall accuracy distribution of slender shaft parts in CNC turning is basically in line with normal distribution.For the radial and axial dimensional accuracy，the feed rate plays an important role in turning.For surface roughness，the order of influencing the machining accuracy of shaft parts is feed rate，cutting depth and cutting speed.
Key Words:shaft parts；spindle blade；CNC lathe；feeding；cutting；surface roughness；normal distribution；goodness of fit；t-test
