Is it 5-axis index or full 5-axis?
Anyway, with 5-axis index easier to fix with a ball gage, but full fifth the only I can thinking of is indicate the table straight.

Does anyone know if thier is a setting that allows you to re-align the C axis for every 90 degrees of rotation.
Reason I am asking we have a 5 axis machine that is running a Centroid controller and our head is not perfectly aligned with the c axis.
In past controllers such as Siemans thier was what I believe was called C axis Wind Up. Where you can adjust the C axis for every 90 degrees so it doesn't through off your x or y.
Any suggestions or help on this matter will be great.
Thanks
Chris

The best way to learn is trial error.
I'm not clear on what you mean byOriginally Posted by Tazzer
also is you "c" axis laying on the table rotating around your "z" axishead is not perfectly aligned with the c axis.
It is a full 5 axis machine.
The C axis wraps around the Z. As the C turns 90 degrees it throws off the X and Y by .015 then if I go to 180 degree it is off .023.
I used to run a Seimans 5 axis before this centroid and thier was a C axis windup setup that allowed you to teach the controller if the head alignment was off you can go in and enter how much your x and y like you would with cutter compensation.
Here is a pic
definetly sounds like a "c" axis mapping problem
I'm not familiar with your control so i can't tell you if it's map able or not
you can call the control manufacturer and they should be able to help you
does the error add up in both directions
or one way adds up and the other subtracts
if both directions add up you may need to adjust your gains(first check for backlash in the "c" axis)
