Hi, I just bought a probe after using the haimer for 3 years now. I'm struggling to understand why you would never probe in Z? I understand that the first wcs is G59, but lets say you put fresh stock in the vice, without parallels, but in the serrated jaws of your vice, and the stock was 50mm higher than the job you are on now, how does the machine know where the top of your stock is in relation to G59 if you have not probed it? Same for your Opp 2 you are showing in the vid, you had to machine the top hat off, how did the machine know how high the parallels were that you chose to use in the jaws if you did not do a Z probe on the parallel?
Good question! Basically. The serrated jaws have the resting surfaces that the stock sits on - those are good enough for OP1. If you model your stock correctly, than there's no reason to probe the top. I don't probe Z here because it's easy to crash. Imagine this - you have 10mm stock, but model it as 12mm on accident. You than probe the top. This will offset all your tool paths 2mm lower, possibly cutting into your jaws. I messed up a set of expensive jaws like this hence why i don't ever do it. Of course my approach comes with a potential crash risk too - if you put in the incorrect height of stock in that does not match the modeled one, your facing pass will be at a much higher DOC. However i don't see how that would happen, and if you're afraid of your operator doing that, you can use the probe geometry feature with a tolerance to check the stock is correct without updating the WCS in any way. On OP2 the reasoning is the same. I know how tall my vice and parallels are exactly, so when i model it like that i don't have a reason to probe Z. If you probe Z, you're relying on unmachined stock to give you the final part thickness, which is also not optimal. And it's also prone to cause crashes. Hope i was able to help!
@@filmatura hi mate, thanks for the quick response. I understand now, because you are modelling everything first, so Fusion knows where the stock to and model should be based off your G59 in the software. Because I’ve always hand done it with the Haimer, I’ve not needed to model in the vice and jaws etc. ok, thanks.
Quick tip - nothing worse than someone thinking they know what they're doing and then trying to educate people with their knowledge!! Hope your machine wasn't too badly damaged when you machined the vice jaw & your boss wasn't around........ouch 🤣🤣 p.s. with regards to FUSION using 1 to 6 for G54 - G59 you'll find this is dictated in the post process. If you want to use the extended G54.1 offsets then this starts from 7 p.p.s probing is useful for probing all your machine axis positions - you just need to understand how to use a Renishaw probe properly 😊
Hey, thanks for the comment, first off im not sure if your first tip is supposed to say im educating people wrong in this video but i will gladly hear any more input on my workflow if there are improvments to make (and im sure they are) My machine was not damaged in any way but my boss was around indeed, as i am my own boss. It sure hurts to have these small mistakes happen which is why i wanted to make this video. ps 1. Thanks for that explanation! ps 2. Im fully aware i can probe all the axes, however using a centering vise for 99% of my work i have no reason to probe any other axis than X, as the rest can remain the same, making it a much more fool proof process and saving some seconds on having to probe my work. Cheers Tom
You are the one who doesn't know what your talking about, I used exactly the same method everyday on a 5-axis machine. This is about automating setups, reducing programming time and errors .
