1. 白鋼刀轉速不可太快。

2. 銅工(gong)開粗少用白鋼刀(dao)(dao)，多(duo)用飛刀(dao)(dao)或合金刀(dao)(dao)。

 3. 工件太高時，應分層(ceng)用(yong)不(bu)同長(chang)度的刀(dao)開(kai)粗。

4. 用大刀開粗后，應用小刀再(zai)清除余料，保證余量一致才光刀。

5. 平面應(ying)用平底刀加工(gong)(gong)，少用球(qiu)刀加工(gong)(gong)，以減(jian)少加工(gong)(gong)時間。

6. 銅工清(qing)角時，先檢查(cha)角上R大(da)小(xiao)，再確定用多大(da)的(de)球刀。

7. 校表平(ping)面四邊角要(yao)鑼(luo)平(ping)。

8. 凡斜度(du)是整數的，應(ying)用(yong)斜度(du)刀加工，比如(ru)管位。

9. 做每一道工(gong)序前(qian)，想(xiang)清楚前(qian)一道工(gong)序加(jia)工(gong)后(hou)所(suo)剩的余量，以避免空刀或加(jia)工(gong)過多而刀。

10. 盡量(liang)走簡單(dan)的刀(dao)路，如外形、挖(wa)槽，單(dan)面(mian)，少走環繞等高。

11. 走WCUT時，能走FINISH 的，就不要走ROUGH 。

12. 外形光(guang)(guang)刀時(shi)，先粗光(guang)(guang)，再(zai)精(jing)光(guang)(guang)，工件太高時(shi)，先光(guang)(guang)邊，再(zai)光(guang)(guang)底。

13. 合理設(she)置公(gong)差，以平衡加工精度和電(dian)腦計算時(shi)間。開粗時(shi)，公(gong)差設(she)為余量 的(de)1/5，光刀時(shi)，公(gong)差設(she)為0.01。

14. 做(zuo)多(duo)一(yi)(yi)點(dian)(dian)工序，減少(shao)空刀(dao)時間。做(zuo)多(duo)一(yi)(yi)點(dian)(dian)思考，減少(shao)出錯機會。 做(zuo)多(duo)一(yi)(yi)點(dian)(dian)輔(fu)助(zhu)(zhu)線輔(fu)助(zhu)(zhu)面，改善加工狀況。

15. 樹立責任感，仔細檢查每個(ge)參數(shu)，避免(mian)返工。

16. 勤于學習(xi)，善(shan)于思考(kao)，不斷進步(bu)。銑非平面(mian),多用(yong)球(qiu)刀(dao),少用(yong)端刀(dao),不要怕(pa)接刀(dao)；小刀(dao)清角,大刀(dao)精(jing)修；不要怕(pa)補(bu)(bu)面(mian),適(shi)當補(bu)(bu)面(mian)可以提高加工(gong)速度,美化加工(gong)效果。
