    I don't have a file handy, but did you make wireframe around your cylinder, use UnWrap on it to get a flat pattern, toolpath that and then just use Axis Sub inside of the toolpath?

    We tried both ways, posts 90 deg off. Transform rotate sends it to Zero deg. 

  2. Would anyone have an example they would like to share, We have a cylinder with bosses, I'm spending way too much time trying to remember how I did this before.

    can't share the file, but think of a birdfeeder shape.

    there was nothing I could find on the tech exchange.

  3. Did some work for "a biG powEr plant". they outsourced the castings from India. There were noticeable ball bearings and other unconfirmed hard spots inside. Nightmare to machine. NDT failed all 6 parts. These were Ø4' X 5' long, bosses on ends were Ø2' X 8.0".  We kept the snake we found in one of the crates in the programming office ( in a terrarium) for like 3 months before the office girls found out.

  4. We did this once. on our VG5000's a few years back,  Machine inspection send back was good but comparing to CMM was off a bit. Machine error will reflect on inspection in the machine. We were able to duplicate it. a few tenths off.  We can't trust that.

    All inspections are now still done in inspection. You can make a lot of scrap checking a part with a machine that is out. We ball bar ours twice a year, but yeah if your gauges  are off, and inspection uses them to check a part, it's still going to be off. 

    IMHO don't do that.
