12、。 當(dāng)使用的砂輪粒度較粗時(shí)，要得到較好的研磨表面粗糙度，可以選擇較高磨削速度與較低的進(jìn)給速率。例如， 300M，直邊的走刀速度可以設(shè)置為0.2m/min；尖角處可設(shè)置為0.5m/min. 600M， 進(jìn)給速度可設(shè)置到0.85m/min 22磨削速度對(duì)表面粗糙度影響： 磨削速度固定時(shí)，進(jìn)給速率愈快，離隙面表面粗糙度愈差。 砂輪粒度愈高時(shí)，磨削速度對(duì)于表面粗糙度影響相對(duì)減少。23Edge situation after different ProcessL:110.46 W:60.46 L:110.06 W:60.06 L:110.02 W:60.02L:110W:60After CuttingA
