Has anyone else noticed that tombstone seems to be broken?

 

If you change the index axis in the FM file and reload the part in tombstone, the part gets oriented wrong and moved in some instances.  The only way to seem to make it correct is to set the setup axis to stock.

Hello Shawn,

A good practice when using Tombstone document is to set the .fm part to "No multi-axis positioning" since the Tombstone document will produce the rotational movement between each setup. This will fix your issue.


The reason why the part are not shifted when index axis is set to " STOCK" it is because it is oriented the same way of your setup one. Index axis UCS represent your initial orientation on the machine when using 4th axis. In your case because you setup your part in a Tombstone document you do not need to specified here any 4th-axis UCS.


As an example if you set Index axis UCS to "UCS_Setup2" you will noticed that the Z direction is opposite to the Setup1 which will result of a 180° rotation in the Tombstone document.


Let me know if that help understand what happen?
