    Also, fanuc told me dynamic fixture offset doesn't need to be programmed to cor, it uses kinematic parameters just like tilted work plane. If you are programming from cor, no need for any options at all. The cam handles the calculations. Honestly, it’s such a nightmare figuring it all out, after...

    And then there is g54.4 which is error correction something or other. 4 axis, 5 axis… doesn’t need to program to centers of rotation??? It’s not like they make it easy to actually figure these things out either.

    Tilted work plane vs dynamic fixture offset. (Both fanuc options for rotary positioning) What is the difference and when should you use either one?

    I've seen this as well. Seems a lot of replies here take for granted the cam -> post processor workflow that "just works". When it doesn't "just work", it's can be a daunting task to figure it out. Modern platforms come with the support and usually a well developed cam workflow that "just...

    same thing, either doesn't have it or don't know how to use it/get cam to output it. It's not that rare for shops to just lack the internal knowledge or resources to figure out real 5 axis workflow. Programming to centers of rotation eliminates the need for having to call the multi axis G code...

    Programming to the centers of rotation eliminates the need for any types of dynamic offsets or tcpc to even be called at all. Most of the times I’ve seen it used are when there wasn’t an off the shelf post processor (or knowledge available to make one) to get the real multi axis features...

    Been in some modern shops that still do it this way. Not the best way to do it anymore but I guess it still works for some people.

    What's everyone's preferred method of verifying 5 axis kinematic rotation point?

    I will have to read through your post a few times to fully get it but on first glance… Focusing only on “z”…. it’s important that the tool length setter “agrees” with the spindle probe length. Therefore if you do a face pass at a freshly probed 0 with a freshly probed tool, it shouldn’t cut...

    What's everyone's preferred method of verifying 5 axis kinematic rotation point?

    is this all referring specifically to brothers and the latest control? Also, is the pitch compensation you are referring to for linear motions? I’m guessing you were just using that as an example for a “locked” parameter. Additional user adjustable (or automatic) parameters for “table weight...

    Mist Collector for Brothers

    Also, the Amano MZ-15 is not really that great, even spec wise. Filtration down to 2 micron, HEPA is something like half a micron I think. That's what it really takes to get the bad stuff out of the air, especially synthetics. I installed an older version of that unit on a DM-1, no TSC, really...

    Mist Collector for Brothers

    The problem is, that's 6gs and then it's probably still a less than ideal system. Really needs some kind of automation so it can drip off between use (waiting for more parts to get loaded, sitting idle...) I bet they will just wire it in so it's on all the time when the machine is powered up. If...

    What's everyone's preferred method of verifying 5 axis kinematic rotation point?

    What are the inputs besides kinematic arrangement, x y z offset (4 geometric) , angle of head (if non square), and angle comps (Interpolated table or similar for a list of abc angles)? Honestly asking as I’ve heard people talk about other settings but never seen any documentation on ones besides...

    What's everyone's preferred method of verifying 5 axis kinematic rotation point?

    Thinking about this more, if anything has to be serviced... not even from a crash but lets say a seal fails somewhere and the trunnion has to come apart. It never goes back together PERFECTLY, makes non-adjustable volumetric compensation useless, and perhaps worse than none at all. Seems very...

    What's everyone's preferred method of verifying 5 axis kinematic rotation point?

    What is modern? What defines volumetric compensation? Sounds like we are getting into murky waters here. I have no proof one way or another but my logic on this is as follows. I'm skeptical this is the case because as soon as the machine moves, the volumetric compensation would need to be...

    What's everyone's preferred method of verifying 5 axis kinematic rotation point?

    This is just the center of rotations, not volumetric compensation, correct? Because of the grob video we now have two things going on here.

    What's everyone's preferred method of verifying 5 axis kinematic rotation point?

    Not necessarily, VCS is a bit more complicated and different than simple kinematic centers (and angles). Maybe someone else can provide some input as I'd like to know more. Is this just some trickery that dynamically adjusts center line parameters based on rotary positions? That's how I would do...

    What's everyone's preferred method of verifying 5 axis kinematic rotation point?

    I don't have hands-on with the more advanced calibration cycles like what's shown on the Grob. Really, I've never seen a Grob with those cycles at all, not sure I've even seen a Grob that new. The video is only a year old after all. I know there are some really good calibration routines out...

    What's everyone's preferred method of verifying 5 axis kinematic rotation point?

    Haha, coming from the guy that pisses on every haas mention here. I agree though. I honestly didn’t mean any disrespect, very easy to fall into one of the bullet point categories I’ve mentioned, most people do and don’t even realize. I’ve just heard the fairytale story of auto calibration...

    What's everyone's preferred method of verifying 5 axis kinematic rotation point?

    It was a rhetorical question…. It doesn’t matter. This is going to sound like a personal insult. Please don’t take it that way. When you say you’ve witnessed multiple machine rotation centers “measured” and then parts bounce between them seamlessly, a red flag goes off for me. This means that...

    What's everyone's preferred method of verifying 5 axis kinematic rotation point?

    Maybe we could pm about it. Not going to post publicly tho. Technically could also be considered partially proprietary because I started building it on the clock for someone else. Something I’ve worked on for 3+ years at this point.
