cylindrical bounding box, not "best fit"

Good Evening:

 

I am trying to generate a cylidrical bounding box around a lathe part with a centerline that is not on center with the cylinder that is created. Imagine an old-fashioned toy or clock windup key with one of the ears broken off. Bounding box "best fits" to the smallest possible size along the z axis; I need to be on center with what would be the key shaft. I do not want to cut eccentric chuck jaws for these parts, even though they would allow use of a smaller stock diameter.

 

I have tried both Turn Profile and Silhouette Boundary to ascertain the stock size with mixed results. We are transitioning from X6 to X7 at work and I have found these two tools differ between versions. There are many variations of the parts in a "family", and after orienting the parts to an identical WCS layout, these tools yield good results only some of the time.

 

I am trying to help out our lathe department, and my background (going waaaaay back) is in CNC milling, not turning. In other words, I am possibly doing a number of things wrong. In addition, my programming days ended with V9.

 

Thanks in advance to the patient souls who might respond.

Good Morning:

 

Yes sir, that is what I need. As the geometry for these parts comes in at various angles and distances from the origin, I have been transforming them to Mastercam's origin, creating a WCS at the center of the shaft, and then creating the the cylindrical bounding box. This seems to work well. I believe this is what JMahon is doing. Hockey Guy™, what was the method you used?

 

Thank you both for your help.

 

Ken
