1、Master CAM 后置处理文件及其设定方法详细说明· 浏览：49· |· 更新：2016-08-06 14:37       Master CAMX版本后处理文件及其修改方法详细说明mastercam系统配置的是适应单一类型控制系统的通用后置处理,用户根据数控机床和数控系统的具体情况,可以对其数据库进行修改和编译,定制出适应某一数控机床的专用后置处理程序。mastercam系统默认发那科后置处理文件的扩展名为pst,称为pst文件。(一般该文件在共享文档shared mcamx5MILLPostsMPFAN.pst)根据

2、本人多年使用经验,初次安装后后处理有以下几点要修改。    (1)默认后处理去掉第四轴A0的输出用记事本或任意文本编辑器打开MPFAN.pst,然后搜索Rotary Axis Settings,找到rot_on_x     : 1     #SET_BY_MD Default Rotary Axis Orientation             

3、        #0 = Off, 1 = About X, 2 = About Y, 3 = About Z改成rot_on_x     : 0     #SET_BY_MD Default Rotary Axis Orientation                

4、0;    #0 = Off, 1 = About X, 2 = About Y, 3 = About Z就可以关闭四轴,没有A0输出。(2)去掉程序开头的注释输出用记事本或任意文本编辑器打开MPFAN.pst,然后搜索"%",找到      "%", e$      sav_spc = spaces$      spaces$ = 0&

5、#160;     中间略掉           spaces$ = sav_spc改成"%", e$      sav_spc = spaces$      spaces$ = 0      *progno$, sopen_prn, sp

6、rogname$, sclose_prn, e$      #sopen_prn, "PROGRAM NAME - ", sprogname$, sclose_prn, e$      #sopen_prn, "DATE=DD-MM-YY - ", date$, " TIME=HH:MM - ", time$, sclose_prn, e$ #Date and time output Ex. 12-02-05 15:

7、52      #sopen_prn, "DATE - ", month$, "-", day$, "-", year$, sclose_prn, e$  #Date output as month,day,year - Ex. 02-12-05      #sopen_prn, "DATE - ", *smonth, " ", day$, " "

8、, *year2, sclose_prn, e$ #Date output as month,day,year - Ex. Feb. 12 2005      #sopen_prn, "TIME - ", time$, sclose_prn, e$  #24 hour time output - Ex. 15:52      #sopen_prn, "TIME - ", ptime sclose_prn, e$  #

9、12 hour time output 3:52 PM      spathnc$ = ucase(spathnc$)      smcname$ = ucase(smcname$)      stck_matl$ = ucase(stck_matl$)      snamenc$ = ucase(snamenc$)   

10、60;  #sopen_prn, "MCX FILE - ", *smcpath$, *smcname$, *smcext$, sclose_prn, e$      #sopen_prn, "NC FILE - ", *spathnc$, *snamenc$, *sextnc$, sclose_prn, e$      #sopen_prn, "MATERIAL - ", *stck_matl$

11、, sclose_prn, e$      spaces$ = sav_spc在不需要的前面加#,就可以去掉注释的输出。    (3)冷却液的开启和关闭用记事本或任意文本编辑器打开MPFAN.pst,然后搜索 "G43",找到pbld, n$, sg43, *tlngno$, pfzout, scoolant, pstagetool, e$这一行,在下边加一行,pbld, n$, sm08, e$,改成  pbld, n$, sg43, *tln

12、gno$, pfzout, scoolant, pstagetool, e$  pbld, n$, sm08, e$   开启冷却液。注意,有2处。   继续搜索gcode$ = zero找到      gcode$ = zero      pbld, n$, sccomp, *sm05, psub_end_mny, e$  改成gcode$ = zero  

13、;    pbld, n$, sm09, e$      pbld, n$, sccomp, *sm05, psub_end_mny, e$关闭冷却液   (4)默认nc文件打开的编辑器修改打开cam软件设置系统配置启动/退出,如图修改后确认退出。   (5)不输出程序行号打开cam软件设置控制器定义,如图修改后确认退出。  (6)有刀库的机器加预先备刀方法打开cam软件设置控制器定义,如图修改后确认退出。 

14、;  (7)圆弧用R,还是IJK的修改。(8)去掉错误文件的生成。（8）攻牙加M29指令用记事本或任意文本编辑器打开MPFAN.pst，然后搜索  Canned Tap Cycle，找到ptap$            #Canned Tap Cycle      pdrlcommonb      result = newfs(17, f

15、eed)  # Set for tapping Feedrate format    if met_tool$,      中间略掉  pbld, n$, sg94, e$      pcan1, pbld, n$, *sgdrlref, *sgdrill, pxout, pyout, pfzout, pcout,        

16、;prdrlout, *pitch, !feed, strcantext, e$      pcom_movea改为ptap$            #Canned Tap Cycle      pdrlcommonb      pbld, n$, sm29, *speed, e$
