Does anyone know of a company that rebuilds (re-true/re-square) small rotary tables? We have a Sankyo RT100 (A/C axes) that has been crashed and is A is no longer square to C. We have shipped one over the pond before but the price was almost as much as a new rotary... any suggestions? Thanks, Jon

On our Mazak VCUs, it will do the same if the back feed is over 200ipm. Has to do with the smoothing parameters. We can take the exact same code and run it on a Mazak Compact or a Robodrill and it wont happen.

So what three points are you taking? Ive tried to get Methods to help us setup these parameters on a robodrill with basically no help at all.

I do this fairly regularly... I'd try to slow the sfm to around 100-150 and .0001-.0002" per flute feed.

Yep. Good path even if you lock it to 3 axis. Good collision control and lead in/out as well

I ended up using morph. Thanks Ron, that got me almost exactly what I was looking for. Here's what I came up with: https://www.dropbox.com/s/ctf4ryhz8bvqi0h/MORPH.ZIP?dl=0 Let me know what you think.

I actually started out using a 1/8" lollipop but I kept breaking them. I swapped to a 1/16 Mitsubishi ball nose and it seems to be more rigid but I cant quite get it how I like it. I think I see what you a saying about the .005" square as the "morph to" chain, but I cannot think of a good shape to use as a "morph from" chain...if that makes any sense. I will poke around with the roughing page, never thought of that! There are so many new parameters and lingo when you go beyond a simple 5 axis curve, just gotta figure them out one at a time!

Ok here is something closer to what i was talking about. I was too worried about stripping the model down. Notice it takes a large stepdown after about 20 passes... any way to smooth that out? Ron, not sure what you mean by driving through a point for morph between two curves. You mean using "to point" for tool axis control? Would morph be able to handle all of the inside undercut surfaces in one toolpath? Thanks, Jon MORPH.ZIP

I had to strip the file down, so I just threw some parameter together real quick. Thanks Ron, I will give this a shot first thing in the morning!

This is the best I can do for now, I cannot share the actual file. Its on a Mazak VCN Compact with a small Sankyo rotary table. Let me know what other information you need. MORPH.ZIP

Yea, ill have to strip it down a little though.

In the attached file, I am trying to cut the green surfaces using a single multiaxis toolpath. Parallel and morph get me close, but the stepover is odd... Anyone care to show me a morph strategy to get some smooth motion? or even better, I single toolpath to finish the whole inside. That would be sweet! Thanks, Jon morph.X_T

You may need to turn off gouge check.

Try decreasing your gap settings.

Did you ever get the sample code for the variaxis? I've been wanting to try this on our VCU.
