摘要


磁力拋光是一種透過磁力去拘束磨料,對工件精密拋光的加工方法,本研究為探討馬達控制模式對於滾筒式磁力拋光的影響,以伺服馬達透過聯軸器帶動滾筒進行研磨實驗,改變伺服馬達旋轉方式,以正反轉運轉方式使磨料在滾筒裡研磨時產生擾動,將表面研磨變得更加平滑及均勻。 本論文針對各個參數對於表面粗糙度及表面移除量之影響進行研究,結果顯示梯形波正反轉平均速度較Sin波形高,因此可得不論對於平均粗糙度還是移除量來說,馬達模式為梯形波正反轉時研磨能力皆較佳。 具導磁性之試片會因為導磁性磨料吸附於試片上造成研磨效果不平均。

Magnetic polishing is a processing method that uses a magnetic force to restrain the abrasive and precisely polish the workpiece. This study explores the effect of motor control mode on drum-type magnetic polishing. The servo motor is driven by the coupling through the coupling to perform the grinding experiment, and the servo motor rotation mode is changed. Disturbance occurs when the abrasive is ground in the drum in a forward and reverse running mode. Therefore, The surface is ground more smoothly and evenly. This paper studies the effects of various parameters on surface roughness and surface removal. The results show that the average speed of the trapezoidal wave is higher than that of the Sin waveform. Therefore, regardless of the average roughness or the amount of removal, the motor mode is better when the trapezoidal wave is reversed. The magnetically conductive test piece will have an uneven grinding effect due to the adsorption of the magnetically conductive abrasive on the test piece.
