HAAS UMC-750: Machining the TACrafted Lathe Toolpost Riser!

Positional & Simultaneous 5-axis machining on the UMC-750 for the first time! A few months ago, I went to Germany and met up with Theo Assfalg from TACrafted for a one-of-a-kind shop tour, which was nothing short of awesome. While there, he talked about his Robin Renzetti-inspired lathe toolpost riser design that he hoped to one day machine. Not only was this a great way to help him out, it was the perfect project to get acquainted with the UMC-750 and CAMplete Truepath Software. Let's talk about workholding, processes, setups, and toolpaths in Fusion 360, the STAR GLOBE, and the ONE mistake we made! Although it isn't perfect, this is still a proud moment for a guy who started out knowing zilch!

[@claeswikberg8958]

it truly boggles my mind how far you have come from a Chinese mini lathe in a bedroom!

[@Swag-sw2li]

It’s really great that you did this for Theo. I’m fortunate enough to call him a friend. Seeing young guys like him with their futures ahead of them makes me not worry about the next generation at all.

[@adhawk5632]

Just found this, TA crafted is awesome. We all aspire towards Renzetti, Gotteswinter and Deimuth. There combind shared knowledge is INCREDIBLE. Thanks you to all involved. Theo's shop is well on its path to excellence.👍👌🇦🇺

[@johnson2207]

When super-gluing the gauge block on, one should not apply glue to the face and then position the block. The glue will add some thickness which will cause a false reading- more than the assumed thickness of the block. The best way is to position the block on the workpiece, keep it held tightly and then apply glue to the perimeter of the block. Keep glue from wicking in from the edges of the block. Super glue can have significant thickness that can throw all calibration off.

[@genixia]

I thought the same thing. Gauge blocks are undersized by one wring thickness which is about 25nm (1 microinch), but superglue bonds are much thicker than that. 3M Scotch-Weld™ General Purpose Instant Adhesive EC2500 series have gap-filling abilities from 0.002" for the lowest viscosity, to 0.010" for the highest. That center hole has a tolerance of -0 to +0.0008" in diameter, yet could be off-center by 0.002" in each direction if a healthy sized blob of glue got trapped. I also wonder about the abuse removing those gauge blocks - impacts or heat could warp them out of flat. I think that would render them useless for further measurement until re-calibrated. Maybe John has a cheap source of disposable gauge blocks?! I would have just changed the probe stylus. Even without calibrating the new stylus it's likely to be more accurate than superglued gauge blocks.

[@Sander_Says]

@@genixia Maybe he used acetone to remove the glue

[@cameronkennedy7820]

So good to see people not afraid to jump into 5 axis and learn a you go. My current job fears 5axis saying 'there's not enough work out there for 3d machining' what about 5 axis positionable work!

congratulations on your first 5-axis part! Just one little mistake but much better than a major crash!

Always liked Robin R's tool post redesign / build. Too cool that Steffan G bumps into Saunders (MW) at HERMLE and makes Robin R's Tool post as first part on his new UMC 750 … It's the interconnectedness of all things (baby)… Or nice when the internet WORKS for yah in a positive way (rather than negative). That's rare. @NYC CNC thanks for making this video UMC looks good !

[@markfryer9880]

For what it's worth, Theo should keep this tool post as it was the first item that you machined on your new 5 Axis CNC Machine. That makes it a signature item of NYC CNC.

[@jcjimenez5327]

What kind of coolant are you guys using?? Looks so clean and not milky

[@IronForestKnives]

Great video! I'm assuming the gouge caused by the part moving in the vise at 13:14?

[@murrayedington]

In fact, despite what you said, those angled surfaces are ideal for a ball end mill on a std 3 axis machine, as the zero-speed centre of the cutter will not be expected to make any contact. But it would be a shame not to make use of the 5th axis!

[@zachary3777]

Maybe. It's a pretty shallow angle, though.

[@multiHappyHacker]

then you have like 10 thou stepovers and lots of movement, put the plane perpendicular to the XYZ on the 5-axis and you can do it with the flat end of the end mill much faster.

[@murrayedington]

@@multiHappyHacker But in fact John's using a ball end mill and the angle of the face he is machining ends up about the same as it would have been if it were simply mounted on its base. He says "a ball end mill always ends up cutting normal to the axis" - but that's only true for horizontal surfaces. The surfaces seem to be curved anyway, so a square end mill wouldn't be much help surely? It's not a big deal but ironically it's one job where a ball end mill works well on a std 3 axis machine.

[@SirBenNo07]

man ! thank for video ! so useful for newbie at veryfirst like me ! by the way,what is your simulation ?

[@DomManInT1]

How many hours did you spend on toolpath programming. What was the actual machining time?

[@trash1652]

Nice work! You guys still working on the J5?

[@MrVlekie]

That's awsome, in the video at 8 min you show a "Star Globe" have you made a video about that, or where can I get more info?

[@danieletinivella8243]

Hi, first of all congratulations on the video. At minute 3:29 what glue do you use to glue the Johnson block to the piece of aluminum? Thank you very much, keep it up ..

[@TAH1712]

0.021mm bore / hole tolerance isn't really tight at all...but still I appreciate your video's very much. I just had to say. it is great that you can have all these fantastic modern and expensive tools. Please make sure you earn a decent return. Perfection is meeting part spec in the agreed time over and over again. I wish you every success.

[@rogerbean393]

Hello, what coolant do you run as it’s looks very clear ?

[@Aspenflight]

Is super gluing gauge blocks an acceptable way to probe your part? Wouldn't the super glue add a non-negligible thickness to the gauge block?

[@nyccnc]

If you measure the dimension (calipers or depth mic), then the thickness is largely irrelevant. Either way, it's a *very* small amount

[@PeteBrubaker]

What kind of coolant are you guys running?

[@MrBobixxx]

best video!

[@NerdlyCNC]

i like the gluing gage block idea....i've just been clamping them with plastic clamps

[@genixia]

I think the abuse of removing those blocks would render them useless for further work, plus the bond thickness is indeterminate and could easily be a couple of thou. I think plastic clamps would be a better solution.

[@bcbloc02]

I think a few minutes with a scotch brite wheel could have fixed up those surfaces, but making another just gets more practice in to dial in the setup. :-)

[@GRTLRS]

8:33 - sounds like a dog-leg rapid gouging the material between passes? Be careful with the dog-leg approach and retract rapid moves while in G234. Do those show up in camplete or does it simulate a straight line move?

[@G53X0Y0Z0]

Super gluing a gauge block on the part would be one of my last options. Milling away the excess material to give the probe stem clearance would be the first.

[@GRTLRS]

Yup. And if you plan ahead, you can mill that clearance from your first operation, so no need for manual cutting. Touch off X0 there, Y0 on either the fixed jaw face, or if on a centering vise on the UMC like that, many times you can rotate B-axis slightly and the probe can reach no problem.

[@raider1628]

how do you create the star globe and use it?

[@QuickStick0]

It looks like a bunch of sketches at a set angle in each direction should only take a few minutes to make in Fusion. you might be able to download it somewhere also through.

[@malcellison8831]

Very cool. Did you make another?

[@sblack48]

I am surprised he didn't choose cast iron. It has much better damping characteristics than steel, which is why it is used everywhere else on the lathe. Cool cnc though.

[@Swag-sw2li]

Rv4 Guy cast iron would not be nice to the insides of John’s nice new UMC and for the toolpost, steel is more than fine. Robin was asked his opinion on this and gave them the thumbs up.

[@stevenoke9390]

Great video John is that a Hermle t-shirt on a Hass video 😁

[@nyccnc]

LOL yes ;)

[@EdgePrecision]

John, That origin your setting in fusion for the 5 axis work. Is that the intersection of the two rotary axis? I take it on that Haas it is the center and top of the rotary table.

[@GRTLRS]

It is about 2" above the table

[@EdgePrecision]

@@GRTLRS So that is where you are putting the origin in Fusion?

[@GRTLRS]

@@EdgePrecision I'm not using fusion myself, but you could put it anywhere you want. Dynamic workoffsets and TCPC on Haas make it easy to setup. Just set your offset like you would normally on a 3axis mill. Only thing is the B-offset must be 0. C can be any value.

[@EdgePrecision]

@@GRTLRS Yes as far as the machine setup (If you have dynamic work offsets). The machine will calculate a position relative to a ideal position of where the cod was processed. But I think in the cam software it would have to be in the actual position irrespective of setup error at the machine. Or in other words as if your machine didn't have dynamic work offset control.

[@GRTLRS]

​@@EdgePrecision Hmm, I think I see what you're getting at. I'm not sure about how Fusion handles that, but in Surfcam I can do both ways depending on post used. The built-in MPost templates will generate code based off the WCS the toolpaths were generated from. In this case, any rotated coordinate systems you would want the origins on the same point. If they aren't, you could have a situation where the verified toolpaths in CAM appear to make a nice part, however the code tells a completely different story. My post for 5axis uses PostHaste. (well, an apt post, then a posthaste template is used.) With this, my coordinate systems can be where ever is convenient for me for toolpath creation. Then the code is generated based off of one coordinate system. That's the origin I setup at the machine. I think I need to give fusion a try to see what's what. It has interested me lately since it looks like it also has an APT post? I could use that with my PostHaste templates, hopefully without too many changes, and have my code formatted mostly the same. I saw on your channel you are getting into fusion now?

[@h.jpouya4715]

what was the coolant? pure water? btw, great video, excelent job

[@DomManInT1]

Coolant used was a water soluble synthetic. Plain water is NEVER recommended for these machines.

[@joni2oo]

You could tilt your A-axis 90up and tauch of one side, then rotate yor C-axis 45 and then touch of the other side.

[@georghoefer9893]

This reminds me when I was an intern 10 years ago. I had to remove those gouge marks with sand paper. Was a lot of fun. Not. Lol.

[@qqqqqqqq1407]

finishing that critical toolpost flat with a gauge length like that is weird. Plus you could have left .002 STL and finish like that.

[@opendstudio7141]

Observation: Why not manual machine the excess away in those areas to clear the probe? Despite the learning curve, the project turned out really nice,

[@DomManInT1]

Or, just install a stylus with a larger ball diameter. Only takes about 20 minutes on the Haas to recalibrate.

[@opendstudio7141]

@@DomManInT1 Probes are too costly for a non-paying job. But with a 5-axis machine you can take a used endmill at the end of it's life, roll B and A, then jog the cuts to get clearance. Most everyone who runs a CNC can make manual cuts.

[@DomManInT1]

@@opendstudio7141 I did not say install a new probe. I said install a stylus with a larger ball. I just bought a 100mm X 6mm stylus for a Renishaw probe for $100 + shipping about 2 weeks ago. But you probably do not know about this.

Nice job on not messing up 98% of it. Why didn't you just change the radios on the transition from vertical to angled surfaces, that would have most likely eliminated the gouge marks on your piece? There is no way I would ever send something out in that shape even just a prototype which this is now.

@@gredangeo The tolerance is NOT "8 tenths of an inch". A TENTH of an inch is HUGE. I believe it's meant to be 8 ten THOUSANDTHS of an inch.

[@gredangeo]

@@menow. That may be the language of Math in schools, but as for Machining. The terminology uses 1 Thou (.001") as the base unit for fine measurements. So 1 Tenth of that means .0001". The logic is pretty simple. No one says 1 Tenth to mean .1". Everyone else says 100 Thou. Like I said, below 1 Inch, 1 Thou becomes the base.

[@menow.]

@@gredangeo Except that he didn't say: "1 tenth", or "8 tenths". He said "8 tenths of an inch", which is 8/10". I know what "A tenth" means in machining and I know what "A tenth of an inch" means. They do not mean the same thing.

[@gredangeo]

@@menow. Well I understood what he said and what he meant. Therefore, saying "8 Tenths of an Inch" was the correct way to say it. I didn't think it was this hard to figure out.

[@donnelson8121]

Why aren’t you using the probe to figure your part orientation instead of using indicator and beating the part straight? And use the probe to measure the bore u used a bore gage for u paid for the probe use it

[@OMY005]

Part has to be indicated parallel to the axis otherwise the verification is useless with close running tool holders to the fixtures. Also, I never probe a high accuracy feature with the machine probe, positional errors in the machine are transferred to the probe also. Calibrated and verifed bore gauge is best for me.

[@ray-charc3131]

Its not a big parts. Better to be done on a smaller machine.

[@gredangeo]

Those coolant lines should be going around the tool. Don't know why they're only on one side. It makes for poor coolant flow to the tool. Bad design.

[@mirokiko]

gredangeo if u use TSC - problem is solved ;)

[@gredangeo]

@@mirokiko Still though, bad design on Haas' part. I'd like to rely on normal coolant flow, and only use TSC when it really matters, like long drills and deep cavities. TSC uses a lot more coolant per minute, it's not economic in the long run. If the outside coolant lines are properly placed it suits most purposes far greater.

[@Olli1591]
