如何制作合理的车铣复合数控车床加工工艺线：

为了提高数控(kong)车床的(de)生产效率，有必要首先(xian)仔细(xi)分析数控(kong)车床加工(gong)的(de)零(ling)(ling)件(jian)，并弄清材(cai)料，结构特(te)征和(he)公(gong)差要求的(de)形式，零(ling)(ling)件(jian)的(de)粗糙(cao)度和(he)热处理技(ji)术要求。然后，在此(ci)基(ji)础(chu)上，选择合理的(de)研磨工(gong)艺和(he)简单(dan)的(de)加工(gong)路径。

加工(gong)技术(shu)的(de)(de)发展：一(yi)般来说，一(yi)个零(ling)件(jian)可以有几(ji)个不同的(de)(de)工(gong)序，不同零(ling)件(jian)的(de)(de)加工(gong)过程，生(sheng)(sheng)(sheng)产效率(lv)(lv)，精(jing)密(mi)加工(gong)成(cheng)本往(wang)往(wang)会有很大(da)的(de)(de)差异，因此在保证零(ling)件(jian)加工(gong)质(zhi)量的(de)(de)前提下，根(gen)据根(gen)据生(sheng)(sheng)(sheng)产的(de)(de)实(shi)际情况，设法提高生(sheng)(sheng)(sheng)产效率(lv)(lv)，降低生(sheng)(sheng)(sheng)产成(cheng)本，进行合理(li)的(de)(de)机加工(gong)工(gong)艺。

加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)路(lu)(lu)线的(de)(de)(de)确(que)定：正确(que)，简(jian)单的(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)路(lu)(lu)线是保证加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)质量和提高(gao)(gao)效(xiao)率(lv)的(de)(de)(de)基(ji)础。选择零(ling)件的(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)路(lu)(lu)径时(shi)，必(bi)须(xu)遵(zun)循(xun)确(que)定加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)路(lu)(lu)径的(de)(de)(de)原则，以(yi)提高(gao)(gao)生产效(xiao)率(lv)。确(que)定加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)路(lu)(lu)径的(de)(de)(de)原则是：必(bi)须(xu)确(que)保加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)精度(du)和零(ling)件表面(mian)粗糙度(du)，高(gao)(gao)效(xiao)率(lv)，加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)路(lu)(lu)径应尽(jin)可(ke)(ke)(ke)能小，以(yi)便(bian)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)路(lu)(lu)径。可(ke)(ke)(ke)以(yi)减(jian)少程序(xu)，减(jian)少工(gong)(gong)(gong)(gong)具停机时(shi)间。 ;数(shu)值计算必(bi)须(xu)简(jian)化，程序(xu)段数(shu)少，减(jian)少编程工(gong)(gong)(gong)(gong)作量。另外(wai)，在(zai)确(que)定加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)路(lu)(lu)径时(shi)，还(hai)必(bi)须(xu)考虑工(gong)(gong)(gong)(gong)件的(de)(de)(de)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)余量以(yi)及车床(chuang)和工(gong)(gong)(gong)(gong)具的(de)(de)(de)刚性，并且(qie)(qie)确(que)定完(wan)成加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)是一种还(hai)是多种方式。同时(shi)，必(bi)须(xu)在(zai)单个子进程，多路(lu)(lu)处理和一次(ci)(ci)性处理中完(wan)成一次(ci)(ci)。这样，可(ke)(ke)(ke)以(yi)减(jian)少工(gong)(gong)(gong)(gong)件的(de)(de)(de)组装次(ci)(ci)数(shu)，并且(qie)(qie)可(ke)(ke)(ke)以(yi)有(you)效(xiao)地减(jian)少操作和夹紧时(shi)间。这样，可(ke)(ke)(ke)以(yi)有(you)效(xiao)地提高(gao)(gao)加(jia)(jia)(jia)工(gong)(gong)(gong)(gong)效(xiao)率(lv)，并且(qie)(qie)可(ke)(ke)(ke)以(yi)保证零(ling)件的(de)(de)(de)定位(wei)精度(du)。

英文(wen)编(bian)程的(de)CNC车床中有(you)很多代码，包括X，Z，U和W X值(zhi)(zhi)，这(zhei)些值(zhi)(zhi)指示(shi)X轴(zhou)上(shang)下(xia)或前后轴(zhou)的(de)运(yun)(yun)动(dong)(dong)。 Z值(zhi)(zhi)表(biao)示(shi)Z轴(zhou)。运(yun)(yun)动(dong)(dong)指令(ling)，这(zhei)两个指令(ling)是(shi)绝对值(zhi)(zhi)指令(ling)，U和W分别是(shi)X轴(zhou)和Z轴(zhou)的(de)相对值(zhi)(zhi)。

采用(yong)U代码的(de)CNC方法，包括：当(dang)工(gong)件中心在原点(dian)的(de)坐标轴X和Z上(shang)，沿Z尺寸和图形(xing)改(gai)变X值(zhi)(zhi)时，从原点(dian)值(zhi)(zhi)开始，如果(guo)倒角(jiao)完成(cheng)其绝对值(zhi)(zhi)编(bian)程也称为偏移量(liang)，可以(yi)(yi)使用(yong)U的(de)增(zeng)量(liang)值(zhi)(zhi)，调(diao)度W值(zhi)(zhi)，没(mei)有必要从源头(tou)计(ji)算(suan)距(ju)离(li)，只(zhi)要将其倒角(jiao)计(ji)算(suan)距(ju)离(li)，就易于使用(yong)增(zeng)量(liang)编(bian)程。但(dan)(dan)是(shi)(shi)通常最好使用(yong)绝对值(zhi)(zhi)而不是(shi)(shi)混淆(xiao)进行编(bian)程，但(dan)(dan)是(shi)(shi)您仍然可以(yi)(yi)部分使用(yong)增(zeng)量(liang)。
