分(fen)(fen)析零件(jian)個加工(gong)(gong)(gong)部(bu)位(wei)(wei)(wei)的結構工(gong)(gong)(gong)藝性是否(fou)符合數控加工(gong)(gong)(gong)的特點。1、零件(jian)的內腔和(he)外形1好采用統一的幾何類型(xing)和(he)尺寸，數控機床加工(gong)(gong)(gong)中心，因為這樣可(ke)(ke)以減少刀具規(gui)格(ge)和(he)換(huan)刀次數，使編(bian)程(cheng)方便。2、分(fen)(fen)析零件(jian)定(ding)位(wei)(wei)(wei)基準上午可(ke)(ke)靠(kao)性。數控加工(gong)(gong)(gong)應盡量用統-的基準定(ding)位(wei)(wei)(wei)，否(fou)則會因工(gong)(gong)(gong)件(jian)的安裝(zhuang)定(ding)位(wei)(wei)(wei)誤(wu)(wu)差(cha)而(er)導致工(gong)(gong)(gong)件(jian)加工(gong)(gong)(gong)的位(wei)(wei)(wei)置誤(wu)(wu)差(cha)和(he)形狀誤(wu)(wu)差(cha)。3、應分(fen)(fen)析零件(jian)所要求的加工(gong)(gong)(gong)精度等是否(fou)可(ke)(ke)以得到保證(zheng)。

數控(kong)加(jia)(jia)工(gong)車(che)槽(cao)時(shi)產生振動(dong)的原因(yin)：（1）刀具伸(shen)出長度過(guo)長，倒致(zhi)剛性降低；（2）進(jin)給率太慢，倒致(zhi)單(dan)(dan)位切(qie)削力變(bian)大從(cong)而引起大幅度振動(dong)，公式為(wei)：P=F/背吃刀量*fP為(wei)單(dan)(dan)位切(qie)削力F為(wei)切(qie)削力，安徽數控(kong)加(jia)(jia)工(gong)，另(ling)外轉速度過(guo)快也(ye)會振刀；（3）機床(chuang)剛性不(bu)夠，也(ye)就是(shi)說刀具能承切(qie)削力，而機床(chuang)承受(shou)不(bu)了，數控(kong)機床(chuang)加(jia)(jia)工(gong)，說白(bai)了就是(shi)機床(chuang)車(che)不(bu)動(dong)，一般新床(chuang)子不(bu)會出現這類問(wen)題，出現這類問(wen)題的床(chuang)子要么是(shi)年代久遠，要么是(shi)經(jing)常遇到機床(chuang)殺1手。

要使所(suo)生成的(de)(de)(de)數(shu)(shu)控(kong)(kong)(kong)程(cheng)序不經手工修改，直接(jie)應(ying)用(yong)于數(shu)(shu)控(kong)(kong)(kong)機床(chuang)加工，則必須針對每一臺數(shu)(shu)控(kong)(kong)(kong)機床(chuang)定制的(de)(de)(de)后置處理器。這就要求開發(fa)人員熟悉所(suo)用(yong)的(de)(de)(de)CAM系統及所(suo)生成的(de)(de)(de)刀具路徑文件的(de)(de)(de)格式、熟悉所(suo)用(yong)數(shu)(shu)控(kong)(kong)(kong)機床(chuang)及其(qi)數(shu)(shu)控(kong)(kong)(kong)系統代碼功能及其(qi)表述格式，而這一工作是(shi)智力密集和勞動密集兼而有(you)之的(de)(de)(de)過程(cheng)。當(dang)面(mian)臨的(de)(de)(de)CAM系統眾(zhong)多(duo)，機床(chuang)及其(qi)數(shu)(shu)控(kong)(kong)(kong)系統眾(zhong)多(duo)的(de)(de)(de)情況下，從(cong)頭開發(fa)后置處理器的(de)(de)(de)工作就顯(xian)得相當(dang)繁(fan)重。
