I like that he said there are about 200,000 Haas machines and there are 200,000 views on this video, and 200,000 subscribers to the channel. Looks like everyone who uses a Haas appreciates this channel.
when human cloning is perfected i really hope Haas start sending a Mark out with every new machine lol.. for real though your a great instructor i have learned much from your videos
Great work as always. Thanks Mark and Haas Automation.
Excellent explanations. Thank you Sir, I enjoy every bit of information..
Another great video as always, Mark! The sound effects of running your edge finder at 10k, Phahaha.... Been there, done that.
I got my first machine with Renishaw probes in 2006. Never want to see an edge finder again. So much faster and capable! I can get X/Y/Z in a single shot, measure angles, diameters, etc. all with the same tool. I also learned how to integrate the macros into programs to check dimensions of a part feature during setup. The edge finder is only there to deal with a day where the probe is out of batteries or damaged. I am thankful for this video since I nearly forgot how to use this traditional method.
Im a big fan of ur channel. Many of useful tips. Thank you. Keep it up.
Nicely done!
Thanks for showing the manual techniques, they can come in handy when tech fails or batteries are pooped!
Thank you for this tutorial helped me out a lot!
Amazing video. Thank you!
Mark Thank you for the instructional video.👍
60fps is realy awesome for this type of videos!!!
Nice boss
Expecting more tips like this
Hey. I live in South Africa. I really like your tip of the day!
But on this tip, it would have been very interesting to see the different work offsets for the different methods. I use an edge-finder a lot. But mostly use a .01mm probe with a 2mm ball... And take the backlash (if any) in a clockwise direction.
Thanks! Very good job.
The other day I broke a probe tip (jogging in the wrong direction!). I immediately felt a little rush of anxiety as I thought "How am I going to set part zero now??". Luckily I had a spare tip and was able to change it and get back to work quickly (If you can call two hours to re-calibrate the probe quick). I have edge finders but my attempts to use them in the past pretty much failed.
Very informative Haas Tip of the Day!
MOAR of these
Thank you for sharing.
Could you make a video of setting tools length offsets on milling center with explanation about theory behind please ?
Great video, but a quick question, on the new machines that have every function turned off with the doors being open now, how would I run the spindle with the door open? Any advice on that? thanks
Thank you!!
Great video Mark. Would be great if you can show how to set Z offset (WCS) with SPI height offset gauge. Thanks
Here are a couple of videos showing how we can set tools using a tool presetter. ua-cam.com/video/A7CwqjU2wg8/v-deo.html, and ua-cam.com/video/uNjMIIRttFE/v-deo.html
Some time trying to remember all this makes my head hot.
Hi Mark! Why you have such difference between these three methods? Did you change the part position? Thanks for the video !!
heimer x=-28.26
edge finder x=-28.16
DTI x=-28.05
was gonna point out the same thing. Need an answer to this
Different parts shown between takes. before using the indicator he even shows himself swapping out to a different block.
Hi Mark, Its wonderful video to learn. I am requesting for the video on Cylindrical part having Horizontal axis. I don't know How to go foe work offset? I also request to make a video for the Indexing Head to do different Mill operation at different angle.I am Eagerly waiting for the video,because I never seen before any vodeo.
Thanks & Co-Operate.
Plz suggest, which would be more accurate and by how much? Haimer, Renishaw probe or Dial indicater? On a machined part for taking work offsets , would appreciate your reply in metric. Thx
how do you find your center on a round part with a edge finder
❤😊 thanks you very much
Thanks 😊
One trick I was suprised not to see is using a multimeter.
If you're machining metal, you can put a multimeter in continuity mode and clip one lead to your tool and one to your stock, and jog the mill until the multimeter beeps when the two make contact.
Smart.
Will chip your tool.
Great, thanks 🙏 I
Is there a way to do de sum and the average of the two values more automatically like with a macro?
about a year ago i was teaching this young guy how to do setups and he had done a few already with me so i didn't feel the need to watch him like a hawk, well instead of putting the spindle at 1000 rpm he did 10000 so as you have seen in this video you know exactly what happened!!!! good thing i was still standing there and able to hit the estop before it hurt anyone as the doors were open hahahaha
just started as a cnc operator i just load parts and inspect them but i want to do more.
What tool holder are you guys using for the haimer? What shank does your haimer have on it? Thanks, great video series.
We got our 3d Sensor with an integrated Haimer CAT-40 adapter, which worked really well. The indicator is fully adjustable for run-out though, so as long as you have a solid hold on it, it will work fine in almost any holder. You can give the folks at Haimer a ring for more information and their recommendations. - Mark, Haas Tip-of-the-day
😂😂 @1:48 That's the night 🌙 shift.😂
I could be wrong, but for the manual indicator off set, we should have typed in MDI G154 P1 G0 X0 Y0 to see if it worked. The G54 offset would be based on the edge finder.
So which one is the most accurate ? It would be super cool to see a final measurement (reference?) with the probe. We could then compare all of these measurements. Thanks a lot.
Thanks for the question. The edgefinder can be pretty accurate if you get good at it, and use .0001 increments, but it is affected by the material you are edgefinding (rough or smooth), so I tell people not to trust it better than .001” (I know, there’s that one guy who can nail it within tenths every time!). The Probe and a Haimer 3d Sensor are as good as their calibration. I trust the Haimer and my probes within a few tenths all the time, because I keep them well calibrated (they don’t really move, I just verify them often). When I need a “second opinion” I always accept my indicator as the final word on the matter. Hope this helps! -Mark, Haas Tip of the Day
Great video. You should do another video setting Z with the 3D indicator. And also using a tool touch off indicator. How to do the math and have offsets to use them in conjunction. And any associated machine settings to streamline the process.
Spoiler alert! Stay tuned, we’ve got more videos coming that will cover much of that. Thanks! -Mark, Haas Tip of the Day
X2 on using the Haimer for tool length offsets. That would be excellent to learn how to use it on my Haas. Thanks Mark
I can't figure it out either.
@@TheRealFrankWizza Here are a couple of videos showing how we can set tools using a tool presetter. ua-cam.com/video/A7CwqjU2wg8/v-deo.html, and ua-cam.com/video/uNjMIIRttFE/v-deo.html
At GE if the machine didn't have a part probe, the machine was programmed to come close to the part & stop then using the hand wheel in .001 we would move the tool towards the part & set the tool using a piece of .030 shim stock. This way is a lot easier then the ways you showed.
Do you have any videos in metric mode?
Thanks for this
Hi cncua - Here is one we did on ER Collets, that was done in metric. ua-cam.com/video/WKikm6cQKh0/v-deo.html. Hopefully, most topics we cover can be understood by both the Inch and Metric people. Thanks. - Mark, Haas Tip-of-the-day

How do you set the machine up to use an edge finder without adding or subtracting the radius? My haas tech told me that you can't, but it isn't being done in this video as far as I can tell.
Never mind, I didn't watch the video long enough.
how about setting z offsets? when i used to work on a haas (i work on heidenhain now so this doesn't apply but i'm still interested) i used to have to touch my tool on my touch off gauge and type into mdi:
g43 h01;
;
;
;
put it on single block, press cycle start, then type that value into the z offset then subtract my touch off gauge. i have a feeling i was missing a setting. the z value always seemed wrong when i used "part zero set"
Edge finder is old school and back in the 80's we never used the G54 work offset at first. we set all tools to top of part and left G54 z at zero. Then we were shown a way to share tools (like a face mill ) for multiple ops. We used the table for the common surface with a 2.000 block or a dial gage. So we took those numbers for tool offsets - then we measured from 2.000 block to top of part and that was usually a small positive shift like +3.050 and that's what we put in Z work offset. That's what we teach at our HTEC school - probe and old school - Like he says - not everyone has probes.
CNC Machinist Education Network when i say touch off gauge, i mean one of these

is there anyway to avoid the g43 h01 etc?
Perfecto:-)
man I wish I had a HAAS
Mazaks are better
Mori Seiki is the best
HELP PLEASE, My 2021 super mini mill 2 do not let me turn on spindle with door open, not even at 300 rpm. what can I do ??? I use an edge finder.
With the method of sweeping with an indicator, he got an offset of X=-28.0565 but with the 3D indicator he got a value of X=-28.2601. Was something moved in between edits?
Good catch! If the numbers don’t match, you have to ask yourself why - and something didn’t add up. We had moved the part in between pickups, and didn’t convey that in the video. Good eye, and thanks for the comment! -Mark, Haas Tip of the Day
my guess is that the tip of the 3D indicator need to touch the surface in some specific depth. If not, the result will vary.
Haas Automation, Inc. hu
nope, it doesn't matter the depth, it should indicate the same at any depth because the tip is a precision ground ball/sphere, with a precise radius, the angle is always the same (of course, only the ball must touch the workpiece edge). if the difference wouldn't be so big (0.2036 in or 0.517 mm), I would say that the edges are not square...
I’m still using a wobbly cos it’s the best
A step can be saved with the edge finder. I find the edge, move up in .001 just above the part in Z. Stop the dial on Zero, Then move X or Y one full turn to Zero. You can see if you moved it the correct direction. Then part zero set. No math.
i think the idea behind the method shown in the video is that if you're still at the point where you're having to wind the wheel to get a visual representation of where your tool is in relation to which way you've wound it, instead of just typing -.1 or +.1 into the offset table, then changing the tool makes sure you're above the job, a little bit safer.
Anybody got any good tips like this for indicating your x and y on a round pin or inside a locating hole? I know it takes practice, but anything that can cut that tedious time down would be great!

Grazie mille per alcune informazioni.
E' possibile avere qualche lezione in italiano? Sono un insegnante di laboratorio e ho un tornio e una fresatrice Hass, dovrei spiegare il funzionamento e la programmazione.
Grazie mille
Attendo risposta
When using a edge finder why not lift it above and move in the radius then rezero...
everything is ok..bt the final method...the x offset value change from the first two method in .1 variation.....
why didn't you just null the indicator so you wouldn't have to divide the coordinates by 2?
My machine won't do 750 FWD with the doors open. Help
@KNP-FAB Same question here. Just bought a 2019 VM3. I don't have instagram account. David
I use an edge finder at work, and I was taught to use M4S1000. I was told that an edge finder can only go counterclockwise. 🤔🤔
TypeUsername34 oh boy😂 , didn't you know that this is only correct for negative values?
@@kingozymandias2988 oh really?? Didn't know. Been working on mills for about 5 months.
TypeUsername34 you're welcome
LOL! And you believed them?
@@anonymousbrown yea. Was barely learning and getting trained on them. Was like my 3rd day and they told me that.
Hej! Jag hoppas att ni kan översäta dina vidioer till svenska eller arabiska. Tack
M4 and m3 makes a difference always spin into part so edges breaks better
Recommend a faster rpm so it breaks harder so u can see 1200
Hey everyone! A viewer just showed me a magnetic edge finder tool that helps you indicate the edge or corner of a part easily, even if the block is at a funny angle. These are terrific, I need one for my toolbox! Check them out and never stop learning!

you can make part your self. or start sell them 89buck. hole thru part then make 90 corner cut. that is cost 89bucks
Never heard of an edge finding chair I see.

Szkoda że nie po polsku, akurat ten film z kilku jeszcze innych jest dla mnie zrozumiały bo często korzystam w pracy z takich rozwiązań. Ale jeśli chodzi o bardziej złożone tematy to nie do końca jestem w stanie zrozumieć o co chodzi. Szkoda że filmy nie są profesjonalnie tłumaczone na Polski.
Bah I say! I like my edge finders at 1200 RPM.
Yup. 1200 RPMs is recommended.
you setup an already machined part, with pecise offsets, but you dont care about orientation of the surfaces !
i think i have a little crush 😳
The video could be better, in showing exact buttons pushed on the control, step by step. There are different methods beside edge finder and this video is lacking on them..
Minuto 2:13; mala práctica.
Using millimeters instead of inches be more practical? Great videos man!

Can you also find the edge by zeroing out one side then going to the other side and dividing by two?
Wow,use an indicating chair if you want to use a test indicator to set zero.

are you showing videos to slum workshop or what? who can buy new machine and can not afford at least dial gauge 3d indicator for few hundreds?
