4th Axis Headache

[Wanny]

Hi

 

Can someone help me with this what has now become a headache.

 

I cut a model of a head on my 4th axis, and when I roughed out the job from the front and back all was ok if I posted the rough pockets seperately ( post outputed A90 and A-90) but if I posted together I got a G55 command instead of the A-90.

I've been trying to figure out why and done a test piece which was an eight sided shape and drilling a hole in each face. When I posted all 8 ops I got the right code A-45,A-180 etc but when I posted just the front and back I got the same g55 code.

 

Any ideas what and why it's doing this.

 

cheers

I am guessing you are doing 4th positioning, are you sure that your ops have the right T/C planes defined for those ops. look in the ops manager to check your ops.

Yes Jay I think so. I've done a lot of searches and investigation into the 4th axis outputs. I put the job in iso view and rotate the a xis i80 for real bottom and -90 for new back. I set the wcs to top and t/plane and c/plane to whatever one I'm trying to machine.

 

like I said the weird thing is when I post seperately it outputs the correct Avalue its just when I try and do both ops at once.
