Man in love with CNC machining and his S13 Silvia combines the two in his garage. You'll see CNC machines being used, CNC machines being built, and mad projects that only someone with a CNC and a Silvia in their garage would do.
You should do a video about using a fiber laser to scape a surface flat. Engrave a pattern across the piece, then blue it, knock down the high spots with the fiber laser, blue it again, etc. It could be extremely accurate, though slow and expensive.
@@machsuper You can get sub-thou because the power is adjustable. You set the power on a lower setting, maybe 40%, etch a pattern, and either make a second pass at a higher power or move on. I think Clough42 has a video with a handheld fiber laser. It would be a killer video if you or someone made that
Hi! I'm very sorry for contacting you in the comment section, as I couldn't get your email, and I'm very sorry if I offended you! I'm Silvia from JLCPCB and I love your innovative projects! I'm sure our custom CNC machining services can highly match your video content and style. I would love to discuss the possibility of working with you. Please feel free to contact me if you are interested!
Harmonic drive / strain wave gearing is not backdrivable (or at least requires a lot of force). Not sure how this affects vehicles, wouldn't need a parking brake at least :)
Is there anything that can, or should be done to try to remove the internal stresses of a large casting of unknown origin and quality before putting effort into scraping it?
I do optical machining and dont really do machine maintenance like this so maybe im missing something. Why cant you just mill the table surfaces to flatten the surfaces and true the table surfaces to the ways? I mean obviously the ways would need to be true and flat first relative to each other so the table runs along the axis true before machining. But it seems kinda backwards to true the table surface first since the goal is to make everything true to the ways in addition to flattening.
As the non-expert here (Marcus is the expert), I think the most important point is that we’re dealing with 0.0001” adjustments. Machining the ways first would require a machine big, accurate and precise enough for milling to that tolerance. Additionally, I’ve learned from this experience that it’s very helpful to start with a big easy surface on the part to give yourself a bulletproof reference plane, and the top surface is the biggest and easiest. Think about how you would get the two separated flat ways scraped planar and flat to each other if you can’t put the table down on anything that you know will return to the same orientation for you to measure from. By scraping the single top surface first, you just need to make a flat surface, so you don’t need a reference elsewhere on the part to measure against. It’s the same when scraping the flat ways on the machine base, we’ll actually scrape the big unused surface between the dovetails first so we have a known flat reference on the part. And that’s the easiest to start with because it sits proud of the ways. Then you can use that surface by sliding an indicator on a stand to measure the flat ways below it. Does that clarify much?
Funny you quit video game art school to do CNC. I'm 12 years into my game art career and now I'm considering quitting game art to get into CNC. Oh how the turns table
How’s it going being in the industry lately? I don’t follow it closely, but it seems like video games and some other software industries are pretty messy right now.
I would have liked a better explanation of what a 'print' is, but overall I enjoyed the video. Always wondered how you bring back a large table back to life without HUGE mills, and grinding tables.
Here's a video series on using a planer, which scrapes in one direction, to restore a mill table. It's a slow burn. Many of the dimensional issues are explained. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QnqRup6Uxcg.html
22:20 The bit about dowel pins was very interesting but I couldn't fully understand it. I tried finding more information on the internet but I couldn't see anything related. Could you expand on it? What do you mean when you say they're not ground between centers?
Dowel pins are centreless ground as it's the most economical way to grinding high volume parts. If you google centreless grinding you'll find more on the topic
I did build my 3axis CNC mill witch turned out really good, now I am thinking about 5axis CNC, but I have doubt that I can achieve that based on my level of knowledge. Keep building and always aim one step higher. +RESPECT
Depending on how much it means to you, is it worth trying and maybe failing or never giving it a go? If you try you’ll learn things either way. Chances are you’ll learn enough to know how to do it right next time.
Step 1 of scraping a hobby mill. Take it to the machine shop and have it surface ground :) One day I will definitely explore the hand scraping, 2/3 plate method, and all the other things that create high precision tools from a piece of metal and a rock.
But doesn't CAM software also generate G-code, just like slicers in 3D printing? I mean there wouldn't really be a reason to bother making a 3D model in CAD if you're just going to rebuild it from scratch by hand in CAM software, so surely a large portion of the G-code must be generated automatically, right? I think I need a sequel to this video. 😭
The shape information from the 3D model is used to calculate the toolpaths. Machining isn’t as simplified as 3D printing, the part isn’t sliced into consistent layers. Features are picked out and machined in whichever order makes the most sense with the whole part in consideration. Considerations like meeting tolerances, surface finish and holding the part between setups. CAM software doesn’t rebuild the part from scratch, it makes toolpaths based on the part.
Well, that autism comment tracks... I'm autistic and watched it all the way through. I think I'll stick to being an engineer for my job, but I might pick up a peace of equipment to scrape in for fun.
Paranoid paranoid PARANOID!!! 😫 im glad im not alone,,, this is what i feel every time i am about to start the machine…. And a minute later im 😮💨😮💨😮💨😮💨 then again to the next machine 😫😫😫
#g20 all day 🤣 g21 weirdos lol jk forgetting to set z is a blasty blast or forgetting your in g54 work offsets setting them for g55 that one is fun too
@@machsuper I'm so "antisocial" I don't like using T9 to text on my non-touchscreen brick phone, so sharing videos takes on a whoooole new meaning 🤣 I'll do it for you though buddy keep on keepin on!!
yeah when i was working on a CNC punch i broke one of the dies because the guy setting up the triangular punch & die misaligned them by 180 degrees making it go bang like a shotgun, the die was worth 1 months worth of my income, scariest thing that happened to me ngl
you know what's funny ? that's not the only cnc that exists, a week ago i stopped working after 2 yrs of working with cnc machine that was drilling and cutting in 14meters parts, like HEB 240 or other shit like that, the funny part is you start it and sometimes, even if everything you did is good, it can make a mistake worth thousands of $ XD Took me 1 year to not stress about it and just go with it at the job ;D
Me: I'm a toolmaker. Friend: Oh, so like you make hammers and wrenches? Me: No, I make molds. Friend: Cheese? What do tools have to do with this? Me: No, Molds are large pieces of metal that come together to inject plastic for everyday plastic parts, medical parts, and so forth. Friend: So... you're not a machinist, you're a moldmaker? Me: A moldmaker is a type of toolmaker, which is a type of machinist. Friend: Okay, so you cut plastic and you call it machining. Me: NAH, I MAKE HOLES. HOLES GO DOWN. HOLE NO GO THROUGH. ME SMASH. Friend: Gotcha.
I don’t like that you ripped off the format of Casually Explained. It seems like you’re trying to capitalize off of his success rather than coming up with your own unique and interesting way to share a story
Machinist from germany here 👋🏻 Thats the absolut worst… you double an triple check everything and can never be safe that everything goes like you think. And the worst of all no matter how experienced you are…. You know in the next 5 years it is possible that a crash can happen… and it probably will happen… i f***ing love it
I've been using dowel pins since the mid 90's and never know there weren't truly round, aside from the scraping lesson I wasn't expecting to learn something like that on this video.
I enjoyed your violin video but as someone who has transitioned and has to supplement testostrone, it was extremely triggering to see cis genitals especially without a trigger warning.
