shiftting a 5 axis program

[Jeremiah]

We have just repaired our pallet cones on our Leblond Makino H1516 5x machine. This is a cradle stlye machine with B over A. The distance from cl of A to the top of the pallet quite possibly will have changed. (they are still putting it back together) I program from cl of rotation and have the pallet/fixtures modeled where they are at on the machine. It would be extremely time consuming to shift all the programs. Is there a quick and easy way to do this? Possibly with the WCS? This distance is not a post variable.

 

Any help would be greatly appreciated.

 

Thanks

Are you only wanting to change the pivet point or the home postion?

It's too bad you hadn't programmed from the center and top of the table and left the post to trig out trunion heights. Now it sounds like your cheapest solution is to modify your posts with a distance value the represents only the difference from what your trunion height was originally. Although it would be quick and you could repost as nessesary, one of the drawbacks will be new jobs. You would then either have to continue to layout your geometry using the old figures forever or create a seperate post for new work either way kinda sucks since its becomming a cluster f#*k. Good luck.

Thanks for the replies-

Cadcam- It is the distance from the top of the pallet to the pivot point of the A axis. This is a Y dimension when at A0 and Z dimension at A-90. Not sure what you mean by the home postition. Can you explain. This is a fixed number that cannot be changed by grid shiffting. But if the distance is greater than before, I can always face off the subplates to where they should be. Another reason I ask this: We are looking for another similar 5 axis machine and more than likely will need to run the same parts on both. It sounds like setting them up like Nominal mentioned would make this possible perhaps with 2 posts ?

Nominal- I will talk with our post guy and see what it would take to get this incorperated into the post.

 

Anyone else been in this situation ?
