Problem with postprocesor on VARIABLE_AXIS_GUIDING_CURVES

Pioneer

Hi I have big problem with posptprocesig on this part.

Tool axis is tilting, and postproceror generate only 3axis operation with indexing. No 5 axis simultaneous operation. Another operation (with variable axis, contour profile or zlevel 5 axis) is always good generate.

This operation is not good.

 

 I have heidenhain iTNC 530. 

 

There is some change in this type of operation. The postprocessor understands it as 3axis operation with indexing.

 

Anyone with any of these experiences?

 

Part is in attachment.

 

Thank you very mutch.

 

Cheers

Hi @Doktorisko,

 

I did check Variable Axis Guiding Curves with an OOTB post processor of NX and I don't see the same issue you are seeing.

 

Can you check with an OOTB NX post processor?

For me it is working, dont know what about ootb pp.

Anyway tool path type variable /debug

So if you didnt make a mistake somewhere there is problem in logic in checking 5axis mode in your pp.

Without your actual post, it is hard to say.

 

**Wild stab in the dark follows**

They are determining output behavior based on mom_operation_type (or a similar variable).

The operation in question is fixed axis contouring, so the post thinks it is "3+2" milling.

and the post logic doesn't check (assuming a mom variable exists) for the tool axis being tilted...

Hi @Ken_A, i have actual postprocesor, but problem is i dont know how to edit my post. I have newer tried edit. Support does it for us.

Look for a command similar to this. I use this logic to turn of clamping on certain operation types. You may have something similar that changes the output mode in your post.

Hi, it's all right.

 

My postprocessor was created very back (NX5 somwhere in Austria) and is slowly editing it with support in Slovakia. He had a strangely ordered logic to evaluate the 5-axis operation. He controlled his operations, and he had the problem with that pad. I did not work so tilt tool axis.

Today everything is all right.

 

Check out my videos, I have a video with a guiding curve.

 

Have a nice day
