Thank you your a boss lol pun intended no less than 2 months ago I needed this answer now a full video thanks guys this is the type of thing that's is setting your business leaps and bounds ahead
I have wanted this tip for so long. Thanks! You guys don't seem to do tips videos very often anymore. Are you just waiting for covid to ramp down again?
We can take a look in the Inspection Plus Manual for all of the optional inputs for this P9823 3-point cycle. You can download this manual on the Bonus Content Page for this video, www.haascnc.com/video/Video-Bonus-Content.html. In this case, we could add an "Ss" value to our G65 P9823 line to have the macro write to a Work Offset once probed, S1 = G54, S2 = G55, no Ss and it won't write to a work offset. I hope this helps. The probed values are stored in Macro Variables as well, you can check out this video for more information: th-cam.com/video/fFZi6rWIcuU/w-d-xo.html
So Mark... I look at my TM-2 and say to myself... this could be a CMM with a heck of a spindle. When could we see macros to run it as a CMM? Toss a part on the table, tell the machine it is so big x, y,z, tell it step values, and tell it to generated a usable point cloud? I know.. Nobody that makes a CMM wants every Hass owner to have this capability, it would be tough on sales... Thanks, MArk
Quality guys cringe at the thought of using the machine that made the part, to check the part, but there are times when this works really well. Renishaw has long touted 'artifact' probing as a way to guarantee good parts. Lets say we have a VF-12 with a long wing spar in it. A second, known good part can be set on the table next to the part we are running. We probe the current part, and compare it to the 'artifact' part, and then make any adjustment. Comparative measurement. Another option is to probe a known Z-Surface (or a ring gage), and then compare our part Z to this known value so we can validate our measurements. Check out: th-cam.com/video/1l1RbDgkbng/w-d-xo.html , and th-cam.com/video/fFZi6rWIcuU/w-d-xo.html , for more info on in-process inspections with our probes
Can I take a newer set of renishaw macros, put them in a classic controller and use the inspection plus cycles to do probing like on the NGC? Or will they work every time after without needing to recalibrate the probe every time ?
question 🙋🏻♂️: on the Haas UMC machine, if I have a round bar sitting horizontally on the table(the bar is parallel to the X-axis), can I pick up the center of the round with B-axis turning 90 degrees then ask the machine to find out where the origin is when the B-axis is 0 degrees. In other words, my origin is the center of the round, instead of pick up the Z at the top of the bar then drop the Z down to what ever radius is, is there any other way I can pick up the part?
I made a macro program for this exact thing. Just store it In memory and the only thing you have to change is the angle, in your case 90° but it can be any angle. I have one for the B axis and one for the C axis. There’s a good TH-cam video on rotation matrices, you’re rotating your work offsets around the macro variables for mrzp at a set number of degrees.
On our Hermle with a Heidenhain control and a Renishaw probe the spindle always orients before each touch so that the probe is always touching from the same direction. Just in case the stylus runout is not perfect. Wouldn't that be a good option for Haas machines as well?
The vector calibration accounts for this within reason for probing on a CNC. The many probe points are used to create a best-fit equation for runout error that is then applied to future vector probing operations.
Interesting. If you run it once, then put an indicator to check for how close it actually is to center. Then run again. Does it get any closer to true center? Maybe a few tenths difference is all I found. But, I do notice that if you get the quick double beep like it was too far off initial center, then it could be off more. That is why I found it is advantageous to almost always run the probing cycle twice
Usually, it's only a few tenths like you mentioned. The further off-center we are, the more error we will see, and the size of the bore affects it too, so for accuracy we want to start near center. This is the case with all probing against an angled or 3d surface, whether probing on a CNC machine, or a CMM. Our approach vector needs to be perpendicular to (normal to) the surface being probed, or we will end up with inaccuracies. Starting very close to center is not nearly as important when using a 4-point bore probing cycle, compared to the 3-point cycle.
This explains why on my Hurco when I probe a bore, it runs a 3 point cycle for me regardless and I just pick the angle of the points, but it always goes round twice. It moves to what it thinks is centre after one cycle then goes again
@@markterryberry4477 I have actually noticed an issue when running the macro supplied on the haas website in just such a scenario, i usually run a bore or a boss probe on my VM6, it moves to the calculated center, then i run it again for improved accuracy. With this macro as supplied this causes a massive error. What would be the best way to discuss \ recreate this for you? is there a way i can send you a video?
It never hurts to run a Vector Calibration cycle. Many 3 point probing routines that come from a CAM system are not using the Renishaw probing cycles, but instead use standard G31 Skip Signal Probing hits. It's even more important, when using straight G31 probing, that we get the probe's ruby tip well-centered, as G31 probing by itself does not take any calibration into account.
no problem. no probe. have dial. probe cost money. take time measuring propably crash probe many times. cheaper for BOSS not buy probe lol. how long it take manually dial center than first probe it crash then need dial manual bcoz sure not have extra probes LOL how long take measure tool lenght. bout same manual and probe. manual just go same place do what ever you allways do paper or cage then MDI custom makro code that calculate lenght like G100. no need change program to measure tool program and change something. we not even use probes on lathe. they are broke or give wrong numbers been fix numbers many times,but after crash they not work properly. faster manual measure anyways LOL. its cheaper and faster do it manually say BOSS. think it like do same job and pay 1000 for it . what you can do manually same fast
Haas puts out the best content! I wish other manufacturers took as much care of machinist and programmers.
Thank you your a boss lol pun intended no less than 2 months ago I needed this answer now a full video thanks guys this is the type of thing that's is setting your business leaps and bounds ahead
Hey Mark. Your ring gauge is really nice.
It is great. It is a PQI 167.1400-1A 1.5" ring gage. The magnetic base makes it ideal for calilbrating on Horizontal mills.
I have so needed this several times this year. Do you have the PDF link you mentioned???
Here you go. www.haascnc.com/video/Video-Bonus-Content.html
Do you have a video on how to rotate your 4th axis against a flat edge, update a rotary work offset. The manual doesn't seem to work for me😞
Can you probe 6 or 8 points of a boss/bore?
I have wanted this tip for so long. Thanks! You guys don't seem to do tips videos very often anymore. Are you just waiting for covid to ramp down again?
Any reason why Haas can't create a canned program in the probing cycles to measure any segment of a circle? Sure would be nice to have.
Have a question, where do you storage the work offset at, because I dont see where you put the work offset in your code? Thank you.

Classic controls have their own Renishaw Probing macros available (they are not interchangeable), that will include these Vector Probing Cycles

So how would one probe a 3 point diameter on a UMC with the trunion at 90deg?

Hi Mark how can i get the bourse content
You can find all of our bonus content, for any of our videos, here: www.haascnc.com/video/Video-Bonus-Content.html
Ive done but my g54 stays the same y
Ok I got it missed S1 as g 54 cheers
use cycle 9901

Do you still need to run a vector calibration even if your CAD/CAM post 3 point calibration code?
My guess is yes. You are calibrating the probe itself not the cad post processor.
It never hurts to run a Vector Calibration cycle. Many 3 point probing routines that come from a CAM system are not using the Renishaw probing cycles, but instead use standard G31 Skip Signal Probing hits. It's even more important, when using straight G31 probing, that we get the probe's ruby tip well-centered, as G31 probing by itself does not take any calibration into account.
Thanks Mark ! I just ran the calibration and test samples. Nice an simple
Fuck yea!!!
we was taught in the army that there is no half circle. Anything less than full circle is arc
Touché
no problem. no probe. have dial.
probe cost money. take time measuring propably crash probe many times. cheaper for BOSS not buy probe lol.
how long it take manually dial center than first probe it crash then need dial manual bcoz sure not have extra probes LOL how long take measure tool lenght. bout same manual and probe.
manual just go same place do what ever you allways do paper or cage then MDI custom makro code that calculate lenght like G100. no need change program to measure tool program and change something.
we not even use probes on lathe. they are broke or give wrong numbers been fix numbers many times,but after crash they not work properly. faster manual measure anyways LOL.
its cheaper and faster do it manually say BOSS.
think it like do same job and pay 1000 for it . what you can do manually same fast
Sorry, but this one is way over my head.
