我自做了一个UGPOST
在绝对坐标系下没有问题,后处理后程序为:
G00 G90 X21.529 Y-31.203 S0 M03
N0200 G43 Z3. H00
N0210 G01 Z0.0 F250.
N0220 X11.976 Y-34.203
N0230 X14.476
N0240 X70.436
N0250 Y33.081
N0260 X22.673
N0270 G02 X27.831 Y21.315 R16.
N0280 G01 Y-14.865
N0290 G02 X11.831 Y-30.865
N0300 G01 X-41.485
N0310 Y-34.203
N0320 X16.976
N0330 G03 X22.72 Y-31.203 R7.
N0340 G28 G91 Y0.0 Z0.0
M30
但在增量坐标系中就没有最后一个圆弧了,后处理后为
N0190 G91G00 X21.529 Y-31.203 S0 M03
N0200 G43 Z3. H00
N0210 G01 Z-3. F250.
N0220 X-9.553 Y-3.
N0230 X2.5
N0240 X55.96
N0250 Y67.284
N0260 X-47.763
N0270 X1.536 Y-1.58
N0280 X1.281 Y-1.796
N0290 X1.022 Y-1.954
N0300 X.745 Y-2.076
N0310 X.452 Y-2.159
N0320 X.122 Y-2.201
N0330 Y-36.18
N0340 X-.167 Y-2.507
N0350 X-.588 Y-2.446
N0360 X-.962 Y-2.324
N0370 X-1.314 Y-2.145
N0380 X-1.634 Y-1.913
N0390 X-1.913 Y-1.633
N0400 X-2.145 Y-1.315
N0410 X-2.323 Y-.962
N0420 X-2.446 Y-.587
N0430 X-2.508 Y-.168
N0440 X-53.316
N0450 Y-3.338
N0460 X58.461
N0470 X1.675 Y.172
N0480 X1.579 Y.596
N0490 X1.391 Y.955
N0500 X1.099 Y1.277
N0510 G28 G91 Y31.203 Z0.0
N0520 M30
而且是同一个程序,为什么采用增量坐标系会增加了几行呢?
请坛主及高手帮帮我
是在后处理的UGPOST BUILDER哪个地方设置错了呀
