Cublex 63 for the win!!! I got it working! There is a Notch Center Frequency and Notch Depth Factor parameter for each axis, and they all have to match for simultaneous movement. I ran into a problem with a zero return margin on A after setting them, but an automated grid shift took care of that! Works pretty good, and I think with a little fine tuning it will work great! I really want to thank you guys for the help! Ryan

No Renishaw It would make my life so much easier at this point..... But I am equipped with a Interapid .0001 indicator. So I started with basics this morning. Pulled the fixturing and started with backlash. There was no value for A, and it certainly needed one. Now machine (G53) A0 is true to the Y axis regardless of coming from A+ or A-. I don't believe it was enough to cause my issue, but progress is progress.... I'm now looking at how true it is at 45 and 90. It seems to be progressively off in A+ (A.010 at 45 and A.018 at 90) which I know the steps per unit parameter would fix, but when I go to A- its different (A-.005 at -45 and spot on at A-90) so I am wary of correcting + and throwing off -. I'm gonna double check those figures, I'll try using feed moves as apposed to handle jog, but any thoughts on that dilemma? I'll try tightening up the angle increment, but I have all the tolerances in the tool path real tight, takes forever to generate the tool path. I did repost with higher max feed, one toolpath runs a smidge over the 3k it was at, and the other kicked up to a little over 7k. I'll try running it in a bit.

I'll try cranking up max inverse in the post to 40k, and throw a 187 in the mix. I'll check and see how it's doing with angle accuracy, I had to fix that on a different trunion a while back. When I talked to the ap guy at Haas, he had me set the corner rounding setting at .06, but it didn't seem to hurt or help the issue. I did talk to Selway yesterday and they suggested getting a tech out. Not sure if it got scheduled, but I'll follow up on that here in a bit. Maybe I can hassle Kevin to figure out the ball bar on a trunion, we just recently invested in one, but haven't had time to apply it to the trunnions. Thanks for all the helpful responses, I've got faith in Haas, I think it's just a matter of getting ahold of the right person to get it dialed. Thanks again!

I'll try changing 191, the applications guy at Haas had me change that to "finish", but I can't tell that it made much or any difference. It's got the high speed option, so it does a great job of smoothly running through all the points. It's all posted using inverse feed, so the dia setting doesn't play a role in that. I'm very tempted to slow down the acceleration parameter on A B, see if that helps. But I'm not certain if that could have undesirable side effects lol.

I'm having an issue with multi axis surfacing. It appears to me that the Z axis will not accelerate fast enough to keep up with A and B. At this point I'm running a test part with 2 different multi axis surfaces. One utilizes AZ&Y and the other utilizes BZ&X. Both of them are faces I used side milling to finish, and the ball endmill is simply supposed to follow the surface. In both cases, I'm getting gouging when Z should be moving up, and floating when z should be coming down. I don't have any issues with XYZ surfacing, they all seem to sync fine. I have a programmed feed of 100 with a max inverse feed of 3000 in the post. All the lines are posting at 3000, which tells me it isn't even running the feed of 100. If I use a feed over ride, or just slow it down, it improves. But even at a 10% feed override, it is gouging at least .003 in the worst spots. This also tells me its not the tool path itself. Has anyone else gone thru this and found parameters that need adjusted to actually do a multiaxis surface at a reasonable feed? It is a new VF6 (came in last October) and a P2 version trunion (with the A axis scale). Thanks! Ryan
