By Heidenhain 530, do I need to modify 5 axis NC code if the material datum is rotated?

[Hans]

Hello,

 

I just got a case use head-head 5 axis machine with Heidenhain iTNC530 controller and probe. The 5 axis NC program I create is working well in the VeriCut simulation. But when the operator clamp the material with a C rotate by probe, the tool angle got problem as my picture. It should be a flat surface by flat end-mill machining, but my tool angle is wrong.

 

When I use wheel to move the spindle, the X and Y can align withe the material. Is there any setting on the controller missing? Or I need to add some M code in the NC code to let the controller to add the rotate angle to the toolpath?

 

 

Thank you!

Are you trying to use the "skew" function to align for "C error" or are you setting a new "C" datum?

[Chipmakr]

I would not believe that code would have to be changed to make this work.

If it's anything like Tilted Work Plane in FANUC, A and C will rotate to create a flat surface so C will be skewed even when you think it should not be.

 

Vericut is not going to show that because you've introduced an external variable into the mix.

Hi Guys,

 

Thanks for your ideas. I found a Heidenhain 530 user. He told me that if the datum in the controller setting is correct, when you put X0, Y0, C0 the rotary table's 0 degree should align to the new datum's X axis or whatever axis should be aligned. So the problem is the operator didn't set correctly in the machine.
