大家好:请问一下GPP2四轴后置处理中的A轴在那里设置才能让它在360度的时候变为0.
           怎样才能让程序做成G91格式的呢？
这是我现在的程序：
N1370 X785.973 Y9.927 Z81.623 A22.846
N1375 X785.576 Y12.639 Z81.797 A20.843
N1380 X784.997 Y16.619 Z81.879 A17.896
N1385 X784.448 Y20.455 Z81.761 A15.042
N1390 X783.979 Y23.784 Z81.499 A12.549
N1395 X783.514 Y27.135 Z81.082 A10.019
N1400 X783.007 Y30.881 Z80.429 A7.162
N1405 X782.516 Y34.602 Z79.579 A4.286

N1415 Z178.756
N1420 G00 A361.975
N1425 G01 Z78.756 F2000.
N1430 X781.676 Y41.233 Z77.538 A359.045
N1435 X781.239 Y44.848 Z76.122 A356.108
