用HeidenHain的CYCL19加工的注意了。

我在做后置时发现，在说明书中，CYCL19三个轴的旋转顺序，说明书（英文）在468页倒数第二段说的是先A，再B，最后才是C。可是，我们的机床验正后，却是先C，再B，最后才是A。会不会是说明书有问题。

是啊，验证都是先C后A才正确。

tilt according to splindle axis first ,then rotatary axis, depending on your machine configuration .For example if your machine rotate "a"  is the axis that control the z axis from vertical to horizontal, it will read this first. i hope
i am correct.

这个应该就是主动轴和从动轴的问题吧

$ s4 g3 I* f/ v$ v3 Z事实上我们用UG编程必须先验证旋转轴C才正确，其他无法和UG一样，而且机器在读程序时候，A,C总是同时出现的，也是一起转的，还有我编的程序也在机床上验证正确了。还有请你用国语，看了你的英文很累。

顶！

i am sorry i only know how to write in english. A axis is turn around in  x axis.B axis is turn around  in y axis.C axis is turn around in z axis. Only rotate A or B will affect the Z axis angle.That why, in program only  can see G80A??C?? or G80B??C??.For example G80A90C180 & G80A-90C0 .The machine tilted the splindle head from vertical to horizontal without rotate the C table, the only different is  X+ become  X- &  Y+ become Y-, for Z remain the same.Above mention is only tested on tilting head machine only(DMU series).

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

When 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.
