一、完整的后处理文件介绍
一个完整的后处理文件通常有:定义字符段、定义字符格式段、定义键值段、定义指令值段、变量定义、程序格式段等部分组成。
下面我们先来看一个比较完整的后处理文件,并把它分为数段,把需要修改的地方做个必要的解释:
machine fanucom —————— 后处理文件头
============第一部分是定义字符段 =================================== define word TN
address letter = \:- \ address width = 13 field width = 25 end define
具体解释:
define word TN —————————————— 定义字段;
address letter = \TYPE:- \————— 定义字段的返回值,比如在后处理文件里有“MS =C ; TN ToolType ; EM =C”,而在写程式的时候选用的是端铣刀,那么在CNC程式里就会有(TOOL TYPE:- ENDMILL);
address width = 13 ——————————— 定义字符宽度,如上\:- \,从T开始算起一共13位,包括空格;
field width = 25 ——————————— 定义返回字的宽度,如上\,如果field width = 2,那\:- \就返回EN;如果field width = 25,那\:- \就返回ENDMILL。 end define
========================== 第二段是定义字符的格式 ================================== define format ( / G6 S T M1 M2 L P D E H O ) address width = 1 field width = 2
exponent width = 0 scale factor = 1 scale divisor = 1 tape position = 0 print position = 1 sign = none not permanent not modal metric formats leading zeros = false trailing zeros = true
decimal point = false 控制公制尺寸的前导零、后导零,小数点 decimal places = 0 imperial formats leading zeros = false trailing zeros = true
decimal point = false 控制英制尺寸的前导零、后导零,小数点 decimal places = 0 end define
word order = ( OP N G1 G2 G3 G4 G5 ) word order = ( + G6 G7 X Y Z B C ) word order = ( + I J K R D S T )
word order = ( + H M1 M2 MS msg EM Q ) 注册字符 word order = ( + Q1 Z2 R2 ID F )
word order = ( + TN TD TR DY MT YR PM )
