bro....that chuck is SO FREAKING perfect..... he re chucked that part and it ran out literally PERFECT....wtf!

[@snakedike]

Had to make one of those (Icosikaitetragon 24 sides) recently for a laser scanner. Needed mirror surfaces and I have no grinder. After milling, it was had lapping over the granite with 1500 grit followed by some buffing compound on a sponge. I have serious tool envy watching this.

[@aj7utu]

It would be interesting to determine how flat the Studer polygons are, given that the flats are interpolated, and any reversal error in the X-axis is being tested. In the case of your method, your flatness is assured.

[@snakedike]

@@aj7utu That's true, and even with grinding I think I'd end up needing to buff out the tool marks. But hand lapping is a terrible way to spend the evening 🙂

[@bboydrummer1]

Absolutely amazing. Nice work.

[@JML1987]

TITAN! This video is pretty related to the dilemma I'm in. The ol' Mill vs Lathe debate. I'm a new mechanical engineer coming from A LOT of 3D printing experience who likes to get his hands dirty and build stuff first-hand for gaining expertise in design aspects and just the overall mechanical experience of making things. But I want to start working with metals. Mainly brass and aluminum but occasionally steels. Before I invest in an awesome CNC setup, to learn the old school ways do you recommend starting with a small lathe or mill?

[@avroarchitect1793]

Amateur machinist here, Lathes are good for getting a feel for the concepts behind feeds and speeds, especially if they are manual (not CNC). But a Mill is far more versatile in what it can do. However Lathes are the kings of threading, cylindrical parts and semi cylindrical/ related parts (camshafts, bushings, tapers, etc), Really depends what you want to make. Honestly to get a feel for manufacturing, both are good, both have their limits.

[@ehamann2309]

Im from Germany. Worked on old Studer. I used to learn not to stop the wheel during measuring. Because the the wheel would suck in the oil and gravity would pull it down so there would be inbalance after... It's not like that nowadays?

[@helpme_obiwan]

So you would flush the grinding area with actual oil, like way oil?

What a great video , use a s31 at work but never seen nothing like that before . Studer at the best 👍

[@adambergendorff2702]

Oh my gosh at 3:51 you forgot the "do" in dodecagon. Well done , was surprised at how much the heat treat warped the part.

[@Resnor]

Ok, If you are going to attempt polygon grinding on a studer you must remember a few things. firstly look at the part Chris has ground. how flat does it look? its clearly radiused on every edge. You cannot achieve flatness using a angle approach wheel. the machine needs to know the exact wheel diameter to achieve perfect flats so you need you use a straight wheel. You cannot measure a wheel at 30 degrees ie wheel 2 as T1 and T11 are totally different sizes. I do many form grinding jobs in aerospace and the flatness is easily within 0.001mm on these amazing machines

[@sobelsonski]

Yes, agree. Also Z oscillation needed, now i can see the radial stone marks on the part.

[@andyvan5692]

love it, great show and tell, and wow, what a piece, and that surface finish. a question, what grinding wheel did you use, as there aren't too many videos showing what is on it, and how to mount the wheels, one assumes it is done by hand?, and not an auto tool loader?

[@leonschumann2361]

haven't u dressed the wheel? (btw u gotta make a factory tour video with the crazy machine park ur running)

[@christophervillalpando5865]

Each of these macros had 2 in process dresses that were programmed. You can check out how I did it on our CNC grinding academy!

[@nonamesareavailabe]

What a great video. I don't have any experience in fabrication but the content you guys put out is highly informative and truly amazing. I'm also wondering if you could make a 2D and a 3D Reuleaux polygon?

[@nathanthomas8184]

Chris have used a Gleason Phoenix CNC tooth cutting Mach ?

[@AraniaTwoFer]

okay, here is a question I have. Because the grinding wheel is cut at an angle, the diameter of its grinding surface is different if you look at different points on the z-axis. the diameter of the grinding wheel that is closer to the chuck has a different surface velocity when it is spinning than the inner diameter. does that have any effect on the surface finish?

[@bdwilson1907]

Surface speed of the wheel on the 45 degree angle is minimal change between the larger and smaller diameter. Typically surface speed is measured in metres per second in the world of metric so the difference is minimal, more so that this wheel will likely be in excess of 400mm (16") diameter in use. Respect to the guys who load these wheels in the machine, I picked one up for our Studer S41 and they are definitely not light!

[@ramonstvol8662]

You ask us what form you should grind next, please grind a Capto Tool Holder so like a tapered 3 sided polygon. That would be nice to see

[@matthewgowan7546]

How did you clock C between the two sides to align the two shapes to eachother?

[@helpme_obiwan]

Its not two shapes. The macro where he input he number of sides calculates the angle.

[@jeffbeck9444]

I dont think he timed one side to the other.

[@berntinulkshredder]

[@jamescerven4400]

[@ChadOHara98]

Ok that's impressive

[@ShopperPlug]

Does this polygon part have real applications or was it literally for demonstration? Polygon parts like the one showed in this video are particularly used with precision lasers, such as used in laser scanners which are used for various of products like a laser printer.

[@Turboy65]

Do an actual camshaft. A full camshaft build that will actually be test run in an engine.

[@npip99]

You can always say "12-gon" and "16-gon". As in, "twelve-gon" and "sixteen-gon". Inevitably you'll have to swap to that pronunciation if you were to ever do an uncommon number or a large number of sides.

[@JML1987]

That's a nice hexadodecakocadagong

[@andyvan5692]

one shape that would be good to do is an ellipse, aka a cam or crankshaft, for engines, etc. and even doing 'off center' grinding, like polishing the journals of a crankshaft.

[@marios449]

I assume it's hexadecagon, deriving from the Greek δεκαεξάγωνο, which is composed of δεκαέξι (=sixteen) and γωνία (=angle), so sixteen-angled. Same way polygon comes from the Greek word πολύγωνο (πολύ = many and γωνία = angle) meaning many-angled

All thanks to Archimedes

[@westrammell8444]

[@alf3071]

Sir Can we do undercut id grinding ?

[@blakeboothe2554]

You should grind a capto style triangle. I’m not sure if that’s patented or not because sandvik created but I think it would be cool cause it’s such an odd shape.

[@zanechristenson3436]

So select a shape, add dimensions. Super complex lol. How accurate are the indexes in arc seconds?

[@MrCdrant]

How do grinders account for wheel material loss?

[@TITANSofCNC]

I will let Chris come in here and answer this. I know that in many applications, you actually re-dress the wheel during the process and the machine automatically knows where the new edge is and compensates / offsets in automatically, then continues to grind. You can set the timing on this based on application and hardness of wheel etc. Titan

[@christophervillalpando5865]

Titan nailed it! The wheel is dressed and the machine compensates for wheel wear. You can pick in your technology for the wheel how much to dress and how many passes. In the programming is where you can select how often you dress, for example before the grinding operation, during or even after. Great question!

[@helpme_obiwan]

is there a dresser calibration cycle for the diamond wheel dresser???

[@jonaskung4412]

You have to calibrate each spindel and dresser once and give the studer the right parameters of the wheel you put in. After you did that once you can work a long time without calibrating again. I work at a studer s42 and i make such a calibration just once a year or so. The only thing wich changes is the diamond wich over time wears down...

[@silent8896]

does the machine has a way to measure where it's at currently ? I mean because of the wear of the grinding wheel, you can't really know how deep it's grinding in practice. Or is it just ignored for short runs ?

[@christophervillalpando5865]

You can use your offsets to keep the part oversized and measure after the initial grind. Then you can adjust as needed. With this run I had plenty of dresses to keep up with the wear of the grinding wheel. Thanks for watching and great question!

Thanks for the reply, I mean.. machine are calibrated and tested at maximum performance when they are built right? They are made for working like days and days no stop at 100% power. Old man machinist thinks that modern machines are like manual mill from the 80s and 90s haha 😂

[@Sebastian-ed5kt]

@@matteomagni2084 i was taught that usually the machine stalls before the tool or anything in the machine breaks. and even tested that with a 85mm facemill. the thing is that stalling the machine can damage the gears if you have a gearbox or the drive for the spindle if you do it long enough but besides that and crashing nothing should damage the machine. and even if the machine has crashed you can run a kinematics check and then the machine should know what's out of the usual and potentially calculate what to do to compensate that. we have a big mill at work where the tower is tilted by 1.2° or so and i think another axis has around 2° bends in it😂

[@CatNolara]

It doesn't just plunge in the wheel, it interpolates the X-axis as well so it creates an actual flat surface. Surer, there might be better ways, but this way you could do the polygon grinding and cylindrical grinding (and other stuff like threads etc.) in one setup.
