| Summary: | 碩士 === 逢甲大學 === 機械與電腦輔助工程學系 === 106 === The main purpose of this thesis is to investigate the influence of machining parameters and milling path on the machining accuracy in the deep groove end-milling for the offset angle of the cylindrical material (SNCM220).
The machine used in this study is a turning-milling machine. The milling path includes contour milling (positive and negative milling) and linear reciprocating milling. The machining parameters include spindle speed, feedrate, and feed per edge. In this experiment, Taguchi method was used to conduct experimental analysis to find out the key parameters, and then get the best combination of parameters. Through the experimental analysis, the optimal parameter combination is: milling path = contour positive milling, spindle speed = 2400rpm, feedrate = 300m/min, feed rate per blade = 0.629mm. This study confirms that this combination of parameters can effectively improve the deep groove machining accuracy of the offset angle, and thereby meet the experimental design goals.
