I used to make parts for a company where some of the designers were former cnc-operators. No really insane parts, no tolerances were smaller than necessary and the RA was often just general.

Imagine uploading a video where the cnc machine itself tells you what it wants. It would save me like a year in education and trail&error.

Hi. If you ever make another polymer concrete would be interesting to see if adding Graphite would make it stronger. According to experiment made by Tech Ingredients channel it should be 50% stronger. If you want to know more watch "Making Graphene could KILL you... but we did it anyway?!" at 41:00. Love you Machine BTW. 👍

Hi, what if I replace the epoxy with resin? Since resin is way more cheaper than epoxy.

I have spent the last 2 weeks trying to get to know about cnc designing and work and I unquestionably learned much more in your 10minute video than over the whole 2 weeks, !thank you!

For epoxy selection maybe try using a deep pour epoxy? Not sure how it would effect your tests, but it has a far longer cure time that what you were using. 3 days to cure. There are some epoxy out there that cure even slower

That vocal fry

Your voice seem need cnc cut.

Very nicely done, thank you for the video

Damn,vthis video is helpful, but the voice is a pain

On a CnC milling machine Do you have a video on how you can take square stock and turn into brown stock? I find a lot about ladies doing this but not on a mill. I have 1 in by 1 in square stock that and what one in 1 in down round... Do you have a video on this operation? :-)

such a good, informative video

Zed. Lol.

What about machining draft angles for moulds? are there bits for that?

Very helpful to mechanical engineer

Aha, this is the base for this :) "Automated Measuring Microscope This is the RapidSight, a 3 axis, automated measuring microscope we developed at MOXER. It sits on a custom designed mineral cast base, and boasts 4 high precision linear stages. Everything was custom designed, machined and programmed by the MOXER team" Interesting!

Thank you !

A really great job and demo. Thanks.

At one point you say to always add fillets to the exterior, but then say to never have fillets on the top part instead gave a champher but if they are going on the out side anyway wouldn't thst make any given side the "top" for that operation? Like how do I know which to use?

The aluminium mold alone costs more than my whole machine 🤯

Excellent! I wish there was a similar video for designing for turning!

Thanks for a very informative video without any "Cool RUclipsr nonsense"

Very informative video but the guy sounds like he needs a cough drop

keep in mind. epoxy doesnt like to stick to aluminium either, so. keep in mind. that it will close up the alu frame,. so make sure the alu is secured to the frame sturdy and secure.

come back ADAM, PLEASE

omg thank you bb

4 years later and still super useful. Thanks!

We use thin stainless steel for moulds, and the resin dosen't stick to it, it's just pealed off once it's set.

Some good basic advice that I wish was still standard in many engineering degrees. That being said some of this is quite dated. For instance flat bottom holes are extremely common with helical milling, in fact that's the go to for many machinists, albeit the length and depth requirements still apply. Similar critique for thread tapping. It's not super common to use taps on a CNC. There's too many thread types and type styles, plus the break easily. If you're tapping on a mill, you're likely thread milling, which does have diameter requirements, but again is basically the go-to for many of not most machinists. Also chip clearing taps are super common. Also, t-slot cutting and undercutting are again super common, but you do have to work within the limits of your tools and common sense. Also never just put break edge. Someone is just going to hit it with a file after it comes off the mill. I've seen some real disasters. Finally, much of the increased costs when quoting with autoquoters is fairly arbitrary - they charge more because they can and that's what their algos and data have optimized for - especially xometry, they're a huge offender with really unreliable quality. They're actually just a re-sourcer, so you never know what you're going to get. If you are machining in house what drives up cost is having to buy more tools and holders for those tools, and added setups. If your CNC has a tool changer, it's common to leave 2 or 3 slots open to change in specific tools for the job. It usually adds very little extra time or cost to fabricating. But nice vid, thank you.

So basically concrete made with epoxy rather than Portland cement. I’m guessing the epoxy is more flexible than cement. I can see any flexing of the aluminum inside causing cracks and failure of the concrete.

That’s pretty wild! I’d love to see of the final product in use. 🇦🇺🤜🏼🤛🏼🍀😎☮️☮️☮️

Bruh, what the f is going on with your voice

I am a mechanical engineering student and I have a product design project using Gen AI and I need information about the algorithms, model and libraries that I can use in this jste project to start my first step in the project and thank you very much

what about mixing glassfibre within?

WHAT A TON OF GREAT INFO IN 11 MINUTES. THANK YOU SIR.

Thank you very much for your advice! 😌

As a logistics manager, I appreciate you adding the stock size to part size comment... however, I often find that CNC programmers have a unique mind, and may prefer to use larger or smaller stock if it means holding a fixture a certain way, making more than one part pert blank, or decreasing machining cycle time. For example, say you have a part thats 2'' thic by 2'' wide. A programmer may request a blank thats 4.5'' thick by 2'' wide, cut into blanks for length and machine two parts from said blank. While technically increasing cycle time, it actually reduces it the total time per part- less time loading and unloading the fixture, and less time cutting the material. And think about it, would you rather have 200 12foot bars strew about because you have to mass manufacture some small dinky part? No! You want a few decently sized bars that the CNC program can make the most use out of.

Even if the pack's and charger's management circuitry will eventually equalise the charge on each cell, would it not be desirable to precisely match their SoC before assembly? Cheap capacity tester boards are available that can be used to do this to within less than 1% (and of course actually ascertain their capacity to similar accuracy - a simple voltage reading doesn't really tell you this).

This video is extremely effective and straight to the point. Well done!

This is an absolutely fantastic video. I do have one question. I’ve already begun the build for my own CNC and the base has been completed already. Would it be a good compromise for me to build an epoxy granite base with a few studs sticking out of the top for me to bolt the aluminum gram to it?

Very helpful video, thank you ! You're saving a lot of headaches for many machinists out there. The only comment I have would be the extreme vocal fry. My Bose speakers don't have a bass/treble adjustment, so it's very difficult to make out the speech.

If you are a Design Engineer "don't be that idiot" who like sending "over the wall" drawings without checking with your machinist first. If not they may kindly turn you down as a design / fabricator relation, then you are screwed. This is beginner video 101 for all wanna be "design engineers" for machined parts.

Can u please share the cad files

Tihis really help me a lot,thanks for sharing~

Is there a mixing technique which will introduce less air?

Thank you! This gave me idea for my master thesis

This video just gives alot of reasons why CNC machining should be avoided in general lol

Thank you well done.

is that good idea to use wood as epoxy granite mold?

You are completely mad and disseminating wrong infornation. Ask any epoxy manufacturer industrial chemist and THEY ALL SAY you must mix Part A with Part B and then add any solids ***to the liquid***.
