| Summary: | 碩士 === 龍華科技大學 === 機械工程系碩士班 === 104 === The slot milling (width 26 mm*500mm) experiments were conducted on SCM415 substrate using ø6 mm, high speed steel end mill by means of modified trochoidal milling method. In this approach, the Taguchi method with orthogonal array. The experimental studies were conducted under different spindle speed, feed rate, cutting depth and cutting width.
Results of the study in material removal rate, the best of cutting data: spindle speed 5251rpm, feed rate 0.09mm/Flute, cutting depth 12mm, cutting width 1.2mm, material removal rate 8515mm3/min, Flank Wear wear width is 0.39mm. Tool wear optimized parameters: spindle speed 4774rpm, feed rate 0.09mm/Flute, cutting depth 6mm, cutting width 1.2mm, Flank Wear wear width is 0.11mm.
