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% I6 h+ v$ Y0 c; z( i: j
1.机器的4,5轴模式. j( H7 F7 P) m: ~2 [8 T
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
9 R) [) R; }4 ^% A2 h0 u
. G0 u- a t. E% E) [0 d5 }mtype : 2 #Machine type (Define base and rotation plane below)
8 u: p* _# z8 F1 P0 `8 g# t5 y #0 = Table/Table
. l/ I* t l% d5 _/ y& y) C #1 = Tilt Head/Table/ U: _6 W' B& v& X8 Z
#2 = Head/Head1 G. J7 D3 a5 f5 a' r8 q
#3 = Nutator Table/Table
" x' u$ u. K& e9 H' A0 ] #4 = Nutator Tilt Head/Table
- ]4 ?% I8 K. d+ g: g& { #5 = Nutator Head/Head
6 ~ o& J! c( G) O. l2.Z轴及刀具长度的计算方式:3 C1 o. ^! U, p# K
use_tlength : 1 #Use tool length, read from tool overall length
. y+ S, I% F9 `8 g" u6 r6 S #0=Use 'toollength' var, 1=Mastercam OAL, 2=Prompt
7 Q- n4 d: J" W; s& q+ Ztoollength : 0 #Tool length if not read from overall length8 @) P/ c, ]+ ?$ |0 z
shift_z_pvt : 0 #Shift Z by tool length, head/head program to pivot (Z axis only)
- w$ _; E, j- T, y1 g5 g& i #0=Pivot, 1=Pivot-Z, 2=Tool Tip Programming (without zero length)* T' m8 W- _) P
#Option 2, So we can still take advantage of brk_mv_head feature' M! |2 W2 @ Y( L& p r/ F* r; B
3.摆轴的长度计算$ s- Z4 q7 T+ y2 {0 y% [9 |
saxisx : 0 #The axis offset direction?' r0 o2 Q& ]: f0 O$ x F& @
saxisy : 0 #The axis offset direction?
7 k. x/ i, t3 Y: E% SSAXISZ : 0 #FOR CHINA The axis offset direction?
2 k0 r' z0 c2 U
0 `7 u& V1 r, x: e只要把以上几点整清楚了就好办了. |
