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. 

I would not recommend inspecting a part using the same machine that made said part. Been there, done that. 

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.

Every new machine we purchase gets it's own steel grid plate made to suit. max overlap of table is a plus. 5/8-11 and Ø.6255 x 2" grid, All our Fixtures fit every machine. The only ones we wont do is our Kuraki's although we did  do the 6 axis KTR 1200.

Some of our machines will not pull a program with an "O" have to rename it with a ":" (colin).

Looks like Cimquest will be doing our install. I'm not going to be responsible for that. 

yeah I misspelled Sandvik.

Thanks for the Novo tip

I didn't know Kennametal had a feeds and speeds app

I'll be signing up for that!

You will enjoy the Carmex Tool Wizard then.

Don't be!  Makes my day less mundane.

After bringing it in, you can try use Mastercam’s decompose entity function

 

I prefer the term Decompose over Disassemble.  

Select them all, export as a .stl file and merge it back in.

The old "Alt F4" should work.

Great... I see another 20% Maintenance increase in the near future. 

were still using (cough)  Focal Point.  SMH

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. 

I wish I knew, Every time I open it I sort by diameter then type. Every time.

Make sure it's a class "D".

Pretty sure you can't unless you define a point in Operation defaults. And don't do that. ever.

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.

My history with Fanuc, I believe It's a parameter setting. Pull out or Dwell and pull out.

imho, small depth of cuts, small tool, don't be greedy. thin parts take time. 

24 CNC Lathes, 5 VTLs, 25 HMCs, 28 VMC's, 3 Trunion full 5axis, 5 Wires, 2 Protos, 1 mill-turn full 5axis, 1 KTR-1200 full 6axis.

7 mill programmers, 3 Lathe programmers.

We are doing a part that is A36. The previous times we used 1018CDA huge difference in getting material to not tear on the corners.

I always finish the minor diameter with an endmill prior to plunging the tool onto the part, some people think undersize is better for drag on the tool, less chatter. But I go slow with molly-D and It's been quite successful in everything from A36 to 316L only cutting the critical area and thread milling after, taps are a nightmare. And don't forget most port tool spot faces are only required on unmachined surfaces. If you mill the face prior only a SF dusting is needed.

Does anyone have an easy way to model internal threads on solids?  External as well? Trying the sweep around a helix and it seems very finnicky. Any help appreciated. Thank you 

Import a Cap Screw matching your thread size from McMaster-Carr, Place it, Boolean remove it. Easiest way IMHO. 

I've cheated this before by making an opposite rad surface toolpath on the inside with the bottom of the tool, and let the back of the tool cut the part. 

I'd load a picture but my "max total size" is set for 1.45 kB.
