用HeidenHain的CYCL19加工的注意了。

用 CYCL DEF 19 并不保证100%安全， PLANE VECTOR才是最好的3+2定位。

5 X6 E6 R2 ~* c: f; MWhen using angles, the error I´m talking about can happen, but not necessarily all the time.  One situation could be fine, another, not; it is up to the frame.  Example: when there is a frame which is only rotated 1 deg or 0.5 deg around one single axis [X or Y] the result, most likely, will be ok.  However, for another frame that is rotated several times around several axes, all by 0.xxx degrees, the risk that the workplane angles contain a little deviation is obvious.

You are saying the machine specification, some m/c with a accuracy of 2.5 ,1 or 0.5 degrees per index on spinldle or table rotation, but from what i known 3+2 axis is not a full 5 axis m/c due to above mention. For example for DMU Series G19 A-20 B10.0 C0 is possible to actitvate it by tilting the spindle 20 degrees with a rotation on c axis( table) inorder to make a rotation on ZX plane by 10 degrees and this is being calculate by

the concept.

坐标的轴的旋转，各机床轴的旋转是不一样的，坐标轴的旋转是坐标变换的范围，坐标变换步骤是一样的，但顺序不一样，得到的结果就不一样。

角度都是一样的，只是换了个马甲，另外顺序换了

期望听雨

如果用cycl19，ABC的顺序非常重要，要改写系统提供的算法。

强烈支持，10楼的同志，PLANE VECTOR才是最好的3+2定位，，我同意，本人用了10年的五轴，总结呀，

HeidenHain的系统功能是非常强大的，找到合适当前加工工艺的才是最好的

那把旋转顺序改了应该就不会出错了把~
