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
% K; ^+ @, ], h8 I1.机器的4,5轴模式
# Z9 \% ~$ q! _0 q& p8 L1 omastercam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 ~/ v7 \8 Q( {# y: F+ O/ v
% U9 X4 B* X5 N( I* H4 O; imtype : 2 #Machine type (Define base and rotation plane below)
9 p0 c# h, ^) d$ D& T #0 = Table/Table
* L( Q6 x: \3 P4 W+ e& C #1 = Tilt Head/Table4 d; g# t6 }7 R$ e2 T O3 {( B
#2 = Head/Head
]9 Q. [1 w( H" n( \/ ~6 p; q7 E' t #3 = Nutator Table/Table
; i; [6 P1 O( c7 C4 _* ]0 h4 s5 p' @ #4 = Nutator Tilt Head/Table, ]4 }+ V! _0 s5 H. K5 \
#5 = Nutator Head/Head
' P4 u2 H2 q" s; w, x! j- t- U7 R2.Z轴及刀具长度的计算方式:
0 y( U T& s. c! z4 fuse_tlength : 1 #Use tool length, read from tool overall length 6 l- [- }" s; V+ m
#0=Use 'toollength' var, 1=Mastercam OAL, 2=Prompt
/ M2 m; o( f& X4 b0 q5 ?toollength : 0 #Tool length if not read from overall length9 x" _% n$ u( W f9 V0 A( z5 [
shift_z_pvt : 0 #Shift Z by tool length, head/head program to pivot (Z axis only)
5 r3 p# o ~ N- |; X #0=Pivot, 1=Pivot-Z, 2=Tool Tip Programming (without zero length)
8 T: Q0 |- c( Y5 n( i* \ #Option 2, So we can still take advantage of brk_mv_head feature
1 P( O3 z4 \: ^3 Q. |! r9 C& D3.摆轴的长度计算
0 y; U; `0 ~2 q0 o. O* X1 Asaxisx : 0 #The axis offset direction?* ?/ d5 i- ^, B) R( R" H3 A( `. t

SAXISZ : 0 #FOR CHINA The axis offset direction?
6 v, ?) |5 H( E6 [ e8 P' o$ ?. W0 j5 c2 m/ `* h
只要把以上几点整清楚了就好办了. |
