C-Head and A-Rotary Table Postprocessor Issue

Pioneer
Pioneer

Hi,

 

I have a machine with A - Rotary table attachment ( Along X) and C-Axis head that rotates about Z axis (Column).

The tool axis is horizontal (Along Y) It is like a right angle head fixed on the chuck.

 

I have tried configuring the below points in postbuilder

 1)  4th Axis Head C in XY plane and 

 2) 5th Axis Table A in YZ Plane

 

However not able to get the output. Request the experts here to advise

 

Many Thanks,

Jithesh

hi

check initial spindle axis setting vector

Hi Juraj,

 

Thanks for your reply. I have tried changing initial spindle axis vector. Still no luck.

Changed from default Z (K) to Y(J).

So if you set A (YZ), C (XY) and init spin axis as 010 you dont get output?

What about you MCS and operation tool axis vectors in NX?

It is possible that your case has no kinematic solution.

Dont forget to set rotary axis limits properly.

Look, for me it is working:

It seems that the level you guys are talking you know to disconnect from a machine model (if it is wrong) - I thought it was worth mentioning. You will not see any effect from changing kinematics when the machine is setting them.

Many thanks Juraj

 

Let me try with dual rotary table kinematics as you have shown in the image.

My machine has C-Axis horizontal head as discussed earlier

It's a Haas multi-grind machine. We wanted to perform both grinding and milling in that

Thanks

Let me tell you one secret, I use table-table kinematics in every 5 axis postprocessors Smiley Happy

Hi Juraj,

 

Many Thanks again !

 

Your trick worked. With dual table kinematics now I am able to get the desired output.

To be honest it should works with head-table or head-head kinematics as well. It is not a trick I just showed you kinematic setting. You probably just set something wrong, I dont know.
