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
+ C) D# ?$ F3 P& r* Q; m0 H2 |1.机器的4,5轴模式7 o& x) U, K" G' W
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
; ~1 D; g7 M8 {2 K' c7 m6 f% H: Q5 g1 C* k4 O( d0 `+ m
mtype : 2 #Machine type (Define base and rotation plane below)
& u5 I* e5 D2 I8 K: M" w& i #0 = Table/Table6 e. _+ ^9 D2 o

#2 = Head/Head
$ j0 C/ O8 z' U5 ]" F #3 = Nutator Table/Table( d: r) N/ |! n7 L2 S* q
#4 = Nutator Tilt Head/Table
- ]+ G' s) e1 q7 V #5 = Nutator Head/Head/ _" B o5 e+ O( z$ F9 `! Z6 y N
2.Z轴及刀具长度的计算方式:" d( e% c" x* U, W' M) M1 \
