數(shu)控(kong)加(jia)(jia)工(gong)(gong)(gong)中(zhong)刀具的(de)(de)(de)選(xuan)擇和切削(xue)用(yong)量(liang)的(de)(de)(de)確定：刀具的(de)(de)(de)選(xuan)擇和切削(xue)用(yong)量(liang)的(de)(de)(de)確定是數(shu)控(kong)加(jia)(jia)工(gong)(gong)(gong)工(gong)(gong)(gong)藝中(zhong)的(de)(de)(de)重要(yao)內容(rong)，它不僅(jin)影(ying)響數(shu)控(kong)機床的(de)(de)(de)加(jia)(jia)工(gong)(gong)(gong)效率，而(er)且(qie)直接影(ying)響加(jia)(jia)工(gong)(gong)(gong)質量(liang)。CAD/CAM技術(shu)的(de)(de)(de)發展，合肥(fei)數(shu)控(kong)加(jia)(jia)工(gong)(gong)(gong)，使得在(zai)(zai)數(shu)控(kong)加(jia)(jia)工(gong)(gong)(gong)中(zhong)直接利用(yong)CAD的(de)(de)(de)設計數(shu)據成(cheng)(cheng)為可(ke)能(neng)。特別是微機與數(shu)控(kong)機床的(de)(de)(de)聯接，大(da)型數(shu)控(kong)加(jia)(jia)工(gong)(gong)(gong)，使得設計、工(gong)(gong)(gong)藝規劃及編程的(de)(de)(de)整個(ge)過程全部在(zai)(zai)計算機上完成(cheng)(cheng)成(cheng)(cheng)為可(ke)能(neng)。

因此(ci)程序(xu)(xu)(xu)(xu)不能太(tai)長，一(yi)道工(gong)(gong)(gong)(gong)序(xu)(xu)(xu)(xu)的(de)內容不能太(tai)多(duo)。數控(kong)(kong)加工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝路線設(she)計(ji)中應注(zhu)意以(yi)下幾個問題(ti)：工(gong)(gong)(gong)(gong)序(xu)(xu)(xu)(xu)的(de)劃(hua)(hua)分(fen)：根據數控(kong)(kong)加工(gong)(gong)(gong)(gong)的(de)特點(dian)(dian)，數控(kong)(kong)加工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)序(xu)(xu)(xu)(xu)的(de)劃(hua)(hua)分(fen)一(yi)般可(ke)按下列(lie)方法(fa)進行：以(yi)加工(gong)(gong)(gong)(gong)部位劃(hua)(hua)分(fen)工(gong)(gong)(gong)(gong)序(xu)(xu)(xu)(xu)。對于加工(gong)(gong)(gong)(gong)內容很多(duo)的(de)工(gong)(gong)(gong)(gong)件(jian)，可(ke)按其結(jie)構(gou)特點(dian)(dian)將(jiang)加工(gong)(gong)(gong)(gong)部位分(fen)成幾個部分(fen)，如內腔、外形、曲面或平面，數控(kong)(kong)加工(gong)(gong)(gong)(gong)廠家，并將(jiang)每一(yi)部分(fen)的(de)加工(gong)(gong)(gong)(gong)作為一(yi)道工(gong)(gong)(gong)(gong)序(xu)(xu)(xu)(xu)。以(yi)粗、精加工(gong)(gong)(gong)(gong)劃(hua)(hua)分(fen)工(gong)(gong)(gong)(gong)序(xu)(xu)(xu)(xu)。

數(shu)控(kong)(kong)加(jia)工(gong)后置處理技術：目前國內許多(duo)CAD/CAM軟(ruan)件用(yong)戶(hu)對(dui)軟(ruan)件的(de)(de)(de)應(ying)用(yong)只(zhi)停留在(zai)CAD模塊上，對(dui)CAM模塊的(de)(de)(de)應(ying)用(yong)效(xiao)率不高，cnc數(shu)控(kong)(kong)加(jia)工(gong)中心，其中一個非常關鍵的(de)(de)(de)原因就是沒(mei)有(you)配備(bei)的(de)(de)(de)后置處理器(qi)，或只(zhi)配備(bei)了(le)通用(yong)后置處理器(qi)而沒(mei)有(you)根據數(shu)控(kong)(kong)機床特點進行(xing)必(bi)要的(de)(de)(de)二次開(kai)發，由(you)此(ci)生成的(de)(de)(de)代碼還需人工(gong)做大量的(de)(de)(de)修改，嚴重影響了(le)CAM模塊的(de)(de)(de)應(ying)用(yong)效(xiao)果。
