mastercam 5轴处理的坐标算法与一般的算法不同.主要考虑有以下几点,这是个基本的方法$ O4 v9 v* t/ _4 F+ {9 Q/ I# T
1.机器的4,5轴模式9 v6 F7 p( O$ n% m
mastercam提供了6个5轴的方案.在使用5轴后处理时,你必需要清楚你的机器4,5的模式.如下, d* `1 t* y( O( `0 H
& x! y4 y! C. B/ Y' d8 {mtype : 2 #Machine type (Define base and rotation plane below)
2 G1 z' x8 |" ?* C$ H" j9 f( F* L #0 = Table/Table
$ j1 z; ^) b* r' b; B) c) {- A #1 = Tilt Head/Table
: h: S$ _+ y4 P0 x: j5 C; S #2 = Head/Head

' D9 L! Z" A" F' q* _: D #4 = Nutator Tilt Head/Table8 b" l H0 o. `! ^- Z0 n2 c( p( n- z
#5 = Nutator Head/Head

use_tlength : 1 #Use tool length, read from tool overall length - _% _# _! E: |7 Y$ f2 Y( b
