Ghosts also break my endmills. It's like Phantom of the Opera but instead of Opera it's just me programming heights incorrectly. I'm really enjoying this series!
I had the same big parts on small machines problem! I ended up solving it by... starting a company, getting a warehouse, filling it with machines, hiring an intern to learn the machines. This plan took many, many, many years more than your 6 hour plan, so from my point of view your plan was pretty darn good.
I cannot wait to see the final product, it's clear you put a lot of effort and love into this project. So far it's looking incredible, hat's off to you sir.
Awesome! As an electrical and electronics engineer with a keen interest in robotics, I had a blast watching both videos, I hope you showcase software development the same way you did the machining parts.
I feel like this channel is what would happen if This Old Tony and Superfast Matt made a TH-cam channel offspring. And I'm enjoying it! Thank you for doing such a good job on story telling and production. I know it's not easy.
My dad who works as a machinest loves your videos. I use the machines as a hobby as well and i love the honest journey and struggle it truly takes to create something.
Your work is incredible, I choose to study engineer because I want to do all of this wonderful work and inspire all the people around the world to get creative just like people like you, thanks for letting all of this education be free for all of us.
hey machine manufacturer here, u should try to add spray mist or coolant. if u use low boiling point liquid theyll take away a LOT of heat. sometimes i use paint thinner or alcool due to the low boilign point, but fire risk is huge if u brake a tool. p.s especially with a machine like this (bridge with nlocked table) u can just make a container around to machine/top of the table with an aquarium pump
@@Cinema_Mechanics Just use the smallest amount possible, never let if unsupervised and have a water bottle ready. Possibly use the alcool in a non tippable bottle or like a squirt bottle. And have the two bottle (alcool and water) well labeled and possible two different color
You rock! As a filmmaker and machinist, i loved every bit of this and cannot wait to see it finished. If you ever need some help getting parts milled, hit me up! I'm set up for basically any camera gear needed. 🤘
Dude 👏👋 That end montage was already cool, now imagine what you'll be able to do with the robot arm when finally built. Here to support you on that journey, you rock!
Very cool stuff. A hint for next time you are doing "sharp corners" is to use a drilled hole in the corner to create a void where the mating corner comes into it. That would have let you mill at least that portion of it in the flat position. Doesn't help your drilled and tapped holes though. Another thing to think about is that you're the designer! Make those corners round and then make the mounting surfaces rounded to match. Really enjoyed the video and the progress that you made.
@@TomZelickman drilling on my cnc is sketchy. I Interpolate all my holes for better or for worse. Which makes small holes tricky. But your point is well taken that there’s always another way. Both with design and technique.
@@Cinema_Mechanics Thanks for the kind reply! I got a good laugh because I noticed after I posted my comment that you used a very similar method to do another part of your fitup. Hope the project keeps going well for you.
I really dig your video style, the explanations and the project itself. It's entertaining and educational at the same time, and really fun to watch! Looking forward to follow the rest of the project and what's to come after.
"this caused my origin to shift". F it. I can't even watch the rest of the video after hearing that. Kudos to you if you kept going. I think I need a beer...
Your channel is pretty cool. A bit funny a bit inspiring a bit dangerous, And a little bit un human.😂 didn’t watch part one, but I will❤❤. I’m subbed 😊😊
Expectations met! Maybe exceeded. Given your profession, you probably know how much more enjoyable it is to watch your videos. Having a good storyline helps. Not sure if that is part of the production values part but it all seems to come together.
Nice Video! 👍Hopefully you will show how you made the final shots! Was it “Marge”? Did you run the camera yourself? Did you pay someone to do it? Or was it “Marger” from the future? 😲 Did you leave the reflections in the glass to chance or did you coordinate it with the camera operator?
I instinctively skipped ahead 30 seconds when you said "now it's time to talk about stress" at 9:20 because skipping shitty betterhelp ad segments is basically automatic for me now. Had to go back after I realized that wasn't the case
Just a thought, but some people have had more success in machining parts out of aluminum by first mold casting closer to spec than a blank would be, then machining from there. He doesn't appear to still be active, but Makercise demonstrates *a* way of doing it if you have next to nothing in existing tools as he makes a Gingery lathe. While a lathe isn't a robot arm, the construction concept is the same.
I do! It’s still a work in progress though and I’m not quite ready to share. But stay tuned!! Everything is very much a work in progress though so always looking for new ideas on the control side.
what are the over all dimensions of your part? (in inches). although less aesthetically pleasing you may have a better time if you make your tapped holes though holes when ever possible or simply drill way beyond the depth you need threaded so you can tap with spiral point taps that will push the chip out the other side of the hole.
I design in metric. I know!!! But it’s easier for me to design in and I’m from the US. lol. The part is 540mmx120mm. So large is always a matter of perspective. It’s hard to tell but I am using a spiral tap. It definitely makes it easier but the process still sucks. Someday I’ll get a tapping head or rigid tapping arm. Someday.
You could at least water cool your spindle for $100 bucks or so, probably won't hurt to have that if you need to finish the rest of the robot! Three other things, with the cnc, it looks like it has a lot of vibration milling, simplest way to fix this is adding weight to the frame, this will dampen the vibration allowing you to get a nicer finish and higher tolerances, 1-3 thou, and will be less likely to break parts and mill bits. Next I'd also make sure your ball-screws in the cnc are well lubricated, sometimes these machines don't have grease there when they are sent so I just want to be sure you did that. (You'll need a grease gun for this, and for the grease I would recommend an NLGI 2 rated grease) Finally work holding, though yes super glue can work, you already noticed and can see that your part is actually still moving every now and then, this is your biggest problem on what causes your error in your parts, it looks like your machine has T slots that fit on the metal base if you remove the particle board from the top, use this in combination with a cnc vise, machinists clamps, or a modular vise (modular is my personal favourite and what, I'd recommend). I'm also studying mechanical engineering to back up this info and have a good amount of experience in the machine shop. Hope this helps :)
The spindle is water cooled. I'm just using a bucket as a reservoir though and don't have any kind of chiller or anything going for it. I also have no specs on what the temps for the spindle should be. So I play it safe and give it breaks. I'd like something more robust, but also hard to justify spending lots of money on a limited machine. Ball screws were rebuilt when I got the machine and I packed em with grease then. Totally right about a better foundation. I'd like to do a tooling plate or the like on there eventually. Just so many projects... Appreciate all the input!
Can you guys tell me is this issue with residual stresses and warping significant? I was thinking to buy some cheap cnc to make similar parts but didnt think it is this complicated
It really depends on the part and what kind of stock you’re using. I don’t really think you should worry about it too much when you’re first learning. And often all you need to do is face both sides of the part a little bit. It was just trickier here because of the size.
@@Cinema_Mechanics we don't shim stuff because we have mistakes, we shim because everything is designed with a shim...but it's always a nominal shim size, so you have the ability to adjust things as you assemble, to be able to hit your tolerance. It's a lot easier to make a shim than to modify a part.
I can tell you in the aerospace machining we do, there is absolutely no shimming. Maybe on skin panels it's done but not on any flight critical assembly.
@@PantamorphJames i can tell u, the machine thath machines ure aerospace toys are all shimmed LOL. like litteraly this week was at a client and i think ther's not a slider or thing without calibrated foil underneath. haha maintenaince is always amazing
Note: micrometers are only to measure diameter. Not thickness. Not sure for the reason why, but every machinist and alumni i talk to say the same thing.

You have a drill press, I'd be searching eBay for a tapping head like Tapmatic or procunier. Nice work tho, they look great.

Shoulda sent that 1st part to Inheritance Machining's box of shame😂
@@RENO_K that would be some prestigious company.

Dependinh on what you are watching yt on, you could get a plugin called sponsort block. That automatically skips the sponsorparts of videos.

Do you have plan on how to control the arm? Like the software, learning how to code,…
I do! It’s still a work in progress though and I’m not quite ready to share. But stay tuned!! Everything is very much a work in progress though so always looking for new ideas on the control side.
