It's fairly amazing to me to watch intricate 3D contour machining like this and realize that the CAM software generates a mountain or code, the G code interpreter interprets that code, and the trajectory planner converts that into coordinated 3D motion on the milling machine, and all of that complexity goes off without a hitch. It's analogous to writing an encyclopedia and not having a single typo. As others have said, the slow motion machining footage is great!
Nice 'UA-cam-atography'; that camera work is top shelf. Then I looked at the link for the camera and realized you must be on the cusp of something big to be fiddling with a camera like that. Seems like a great fit for a tool vendor to have an established UA-camr demo-ing their products to viewers like us; there's a lot I've purchased over the past year as a result of seeing it on yours, Tom's, Adam's, Stan's, Kieth's and so many other channels. Keep up the good work and looking forward to the open house.
It's fun to press 'pause' every couple of seconds during the intro to see the awesome expressions on John's face. It always makes me bust a gut. Awesome vids otherwise too! Big fan.
John, great video! Interesting video, perfect music for the machining section, good lighting, and educational subject matter...what's not to like? I didn't realize that machining CAM software could deal with stl files. Stl is usually used for 3D printing (my guess is that it's short for stereo lithography). When you are dealing with flat slices through a part a horde of triangles at odd angles isn't too hard to deal with...where a plane intersects a triangle is fairly simple math. Turning that sort of data into reasonable tool paths is a whole other level! I've seen similar machining done on wood by gantry router CNC machines. With those they tend to do raster passes...not like your paths where features were shaped more or less separately. The raster pass method can do roughing with big bits and large stepovers, followed by finish passes with smaller bits and finer steps. Not sure of the CAM software for that, but I think one is called Vcarve Pro. The Legacy Mill folks do some of that sort of stuff. I wonder how long it will be before the 3d printing in metal comes down enough in price to be in the same market segment as Tormach? Probably less time than we'd guess. The Dragon 2 spacecraft engines are 3d printed...that surprised me, but us really cool! Sometime could you explain what the "water level" concept is all about? You've mentioned it a bunch of times, but since I haven't used the software you are working with, I'm not sure I know what you mean. ADVthanksANCE! -- Mike
John, Thanks! I get the general concept. I'll see if I can follow how that gets applied in some of the machining situations and how the CAM software deals with it. -- Mike
That's really interesting. I recorded a coin milling video a while ago which i have yet to edit (will likely be up sometime in March I guess) where I make a brass coin not too dissimilar to the one you made, but on a milling machine not designed to mill metal at all, the Roland MDX-40a. Since I could make the CAD myself I actually mixed NURBS and mesh data, so the text and such could be easily set up in CAM, and the mesh could be used for the more intricately shaped parts. The mesh ended up being around 500k faces though, and my laptop swallowed it like it was nothing. I don't think I'll focus much on the CAM aspects in the video though, more on the CAD. I ended up using an engraving cutter though, as I figured it would significantly reduce the load on the rather weak machine. You're really selling me on the Tormach though, can't wait until I can start setting up my own workshop again. I really like the end result, and interesting to see what you were able to do without having access to NURBS data.
NYC CNC The Roland is okay, and for the price it's a very capable machine if you're only doing softer materials. The main issues I've had with it is the work holding. Since it has so low Z-clearance you basically have to resort to fixing everything with double sided sticky tape if you do anything with a bit of height to it, which then for smaller parts may just not be enough of hold down force even with some of the tapes specifically designed for the task. I've had it launch some smaller pieces across the machine as it tore them loose. For the coin I had to design a whole new bed for the machine, so I could basically screw my workpiece down. It is weak, and if you push it just a little bit too hard it will jam the cutter in the material, trigger the overload protection and force you to shut down the machine. So in one sense it's good that it has that protection, but on the other I really wish it had a bit more torque behind it so you could ramp up the speed a bit. Because of the risk of crashing during regular runs we've ended up having to run it quite slow, with minimal chipload, just to be on the safe side. I could definitely see myself getting one for myself though, as it's great for smaller operations. Though, it's a few years old, I bet there are newer better models on the market by now. Fun story, I ended up starting a fire in the machine once though, with a dull endmill and milling plywood. The chips started smoking and set of the fire alarm. Quite fun having to explain that to the fire department at four in the morning. Haha!
Thanks for the video John. Really enjoyed the tight shots of milling procedure. That tappered mill with the ball point is cool... Will checkout Tools today.
Wow! Your channel gets more professional with every single video. Those are some awesome shots! But you need show us the finished coin! You can't withhold from us :D Awesome! Have a nice day!
Very cool. Hard to see any material being removed by the 1mm mill. ToolsToday just called and wanted me to ask if you could make them some coins out of stainless?!!?
Sad, and good thing, is that you can't sell this (outside of an auction among your fans) based on the value of the machining... Because a slightly crapier version could be made with a mold, en mass. Which I imagine is how they do actual coins, that or they press the design into them. Still, this is really cool.
HisRoyalCarlness You should check out some minting videos. Coins are minted, which is a fancy word for being stamped using dies, with many tons of pressure behind them. The dies however are quite commonly, these days, milled using CNC milling machines. Back in the day they used to be hand engraved and polished.
+Switch & Lever the really expensive specialty coins are still handmade (the dies) and polished. they are also pressed deeper then the circulation coins. There are some really cool videos on it like you said.
so would you be able to flip this over to get a reverse image...and then mill a die to press these out ...??....or would it be too long winded ive only done cnc turning and find milling a challenge....but im learning what can and cant be done
That high speed video looks great! I checked out the camera you linked to in your last slow-mo video, do you own that bad boy? I'm very envious! Seems like it was doing a good job taking marco-ish video too.
Regarding your issue with the waterline, it may be your PC and limited memory, but I doubt it. (You can confirm by opening up a Performance meter and watching memory use). You are likely running into numerical/topological issues in slicing. Near-tangent intersections are the worst nightmare in building these things.. If I might beg a favor, would you mind trying waterline with the bottom depth being slightly higher than the bottom surface of the recess on the coin? I'm betting that Sprut ran into real problems with not-quite-parallel planes at the bottom (not due to model construction, but due to numerical noise because these are digital computers). if you don't have time, I understand. You have a couple of businesses to run..

great choice of music for the slowmo, really mesmerizing
Beautiful! I usually hate music over machining video but that was exquisite! [Says the guy who just did a machining music video.]
It's fun to press 'pause' every couple of seconds during the intro to see the awesome expressions on John's face. It always makes me bust a gut. Awesome vids otherwise too! Big fan.
NYC CNC I'd never say that! (except, who isn't?)! Expressive and enthusiastic, yes! That's why we're all here.
Nice job. Can't beat some micro machining
Wow. Now that's some tight detail.
Well done. A fantastic result. I'll be coming back to this video when I take delivery of my PCNC1100!! Thanks for giving tool details and speeds:)
Looks soooo cool :D!! Excellent video. Machining at this scale requires lot of patients and great eye. Thanks for sharing. Loved watching it
Absolutely amazing! An art in its own right.
That was some cool machining John!
Saw this vid on "Tools Today" channel already. Still cool and deserves a Wooo Buddy!
Fascinating to watch a matrixed cutting pattern. Traditional coin die cutting is done with a circular 3d pantograph or a janvier.
Very cool! Can't wait for your open house1
Wow thats just..... No words.. ☺ congrats, very well done
Great Video! Awesome slow motion shots!
Wow what fine work. That came out superb!
Would loved to have seen a final shot of the coin in your hand. Love the new slow motion camerawork tho
Awesome video I love the slow action footage and the music. Its almost like watching an intimate dace.
John, great video! Interesting video, perfect music for the machining section, good lighting, and educational subject matter...what's not to like?

So awesome. This is one of the reasons I want to convert my mill to cnc. To make molds for silver coins. Would be awesome
Keep up the HD slow mo! The tool review with shots of the tool is great, maybe link to the tools themselves?
I often wonder what the tooling setup is to make those TEENY TINY milling tools. Holy cow!!
Google "rollomatic". 5+ axis grinders for carbide end mills, inserts, or many other cutters.

Is it just me or does John sound like a different person in the ToolsToday videos? :) I think I prefer the NYCCNC John. More excitement and upbeat :)
Thanks for the video John. Really enjoyed the tight shots of milling procedure. That tappered mill with the ball point is cool... Will checkout Tools today.
WOW that was amazing, How about knocking me off a few double Eagles ;)
Thanks for sharing your video
Great video bro. looks like fun
Wow! Your channel gets more professional with every single video. Those are some awesome shots!

Awesome! Have a nice day!
Very cool. Hard to see any material being removed by the 1mm mill. ToolsToday just called and wanted me to ask if you could make them some coins out of stainless?!!?
Great video, shame that you guys are still working in Imperial though.
Nice work, just think how long it would take to try and do that manually.
Buddy
beautiful video! but the end ?

james mason are you thinking of making a coin
wow this is awesome!!! would you ever do this in Fusion 360? Can you do this in fusion 360?
I run big CNC machines. And robotic welders.
Oh my! what camera did you use for the slomo stuff? I gotta get one for my millling vids. It's hypnotic.
SprutCAM looks good, but expensive?
That high speed video looks great! I checked out the camera you linked to in your last slow-mo video, do you own that bad boy? I'm very envious! Seems like it was doing a good job taking marco-ish video too.
NYC CNC Sweet! We are planning on renting a slow-mo camera as well. You beat us to it!
What is holding the work down? Glue? I don't see where the vise jaws actually grip the material.
Hello there, does it offer smooth edge finish?
Was the shop tour thingy last weekend? how was it!?
WOW ... I am still working on my plate .
NYC CNC still working on my fixture plate .you do mind blowing work
Hi dude.. trying to get into cnc.. i want to start small with adobe and 2d printing.. looking for a good machine to start with.. any advice?
Hi John, is it possible to retrofit a air spindle to the Tormach so it can do some high rpm work?

if you don't have time, I understand. You have a couple of businesses to run..
please how can i choose bits to do this work.thank you
Do you have that Spindle Speeder kit from Tormach John? Looks that your RPM worked out really really well even if that was stock Max 5100.
1mm end mill @ 5100RPM... I calculate 52 sfpm. Haha.
Make some gold coins from bulk!
ty
Is it just me, or does the video make it look like that 1mm end mill has a lot of runout?
how much this work costs? how you calculate price of cnc machinig 3d shapes?
Still some “scan lines” visible. Does your customer then polish those out somehow? Some other dark art to it?
