As a newly graduated mechanical engineer, thanks for teaching what we actually wanted to learn!

As a mechanical Engineer, this is one of the most helpful videos I've ever seen. I'd love for another video similar, but with more advanced topics (flatness, perpendicularity tolerances wrt features done on the same vs multiple setups ... etc). Great content!!

At this point im just going to comment every time I come back to this video, to reassure my self before I submit a design to be fabricated. This is an extremely informative video👍🏾

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.

Surprisingly great video to find on KZfaq! Packed with accurate information and no fluff. Please make more!

Ima a self taught product engineer. Its amazing how many time i come back to this video, when designing parts. It literally answers 90% of what ever design flaws im making.👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾

What a fantastic video. As a machinist I thank you and will be forwarding it to my design team. Very much appreciated!!!

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!

Fantastic video! I'm a design engineer with a bit of machining experience and this is an incredibly concise, comprehensive and accurate view on designing for milling. I especially liked the deflection graphic and math. Looking forward to seeing more videos my dude

Watching this ten minute video just helped me save a lot of money. Excellent clear and simple information. Subscribed!

You don't need to add forced vocal fry to sound pro. In some parts you sound normal and those are way easier on the ears.

I work as a CNC programmer and the amount of times I get a cad models that people poorly design, and then expect to be able to machine , is just mind blowing. I often have to go back and make some suggestion on how to change the design to allow for easier machine. Thank you for this video...

As someone who is designing milled parts for product design this video is invaluable. Subbed👏

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.

Absolutely great video man. Very clear to understand. I'll forward this to teachers!

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

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

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.

Whoa. Thanks so much for this video. So much useful information delivered clearly and quickly. Cheers!

It is even easy to understand for me, even though I am not a machinist,I am just a project manager who are working for promoting the cnc machining services in China.

Dude! Fantastic video breakdown! If only more engineers understood this 🥴😵‍💫

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

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.

The crispy deep fry voice is too distracting 😂

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

Fantastic presentation and explanations. Thank you.

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.

Wow! such simple and cleared explained concepts.

such a good, informative video

Great video - thanks! If you make something similar for lathe parts it will be very useful.

Thank you for the info. Waiting for more on turning and fixtures..

Very helpful to mechanical engineer

Adam this is an amazing video. Please make more videos like this. Subscribed.

Very clear and excellent video!

Really well done! Thanks for the video and Merry Christmas.

nice video but are you an extremly heavy smoker or something

Great basic information!

This is a fantastic video. Thank you

Great stuff, but definitely try to avoid the monotone. Also you should rename this video to CNC Milling and also make a video for turned parts.

Thank you very much for your advice! 😌

Tihis really help me a lot,thanks for sharing~

2:10 For pedants, the words diameter and length are switched for this timestamp.

Truly Great and informative video 👍🏾👍🏾

Thank you !

Great info! I had a hard time hearing you though, perhaps its your microphone.

Do you have pdf content of this video. Excellent!

About to give a presentation on this, was watching videos to see if I'd forgotten anything in my notes... INTERNAL FILLETS SUCK! XD

Good stuff... The floor radius information isn't exactly right though. Using a small floor radius can work really well if you're using a radius endmill, as a 10-12mm endmill will have about a 1mm corner radius, this means that you can go for a fine floor radius with a wide vertical corner radius. Additionally, the undercut feature you've drawn isn't possible to machine, but there are t slot cutters and dove tail that do a nice job of particular feature types, so as long as you're standardising on those feature types undercut isn't a problem at all.

This is good information.

Great video , really helpfull, Thank you

It is a really great content. Keep it up!

Speedymetals is also pretty good about price/selection.

great video, thank you

great video

Those top fillets aren't too terrible if necessary... As long as you pick a radius that is a standard cutter size. Search "corner rounding end mills", and usually the smaller you can live with, the better!

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?

nice contents I hope you keep update :)

Great video

found this via Hackaday. Subscribed because of this video. Great work.

Very informative

wow, really helpful!

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

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? :-)

Excellent, more! 🙂

Are these "design rules" covered in the mentioned books? If so, I guess they are a must read for any engineers like myself!

@6:29 I've heard you should avoid bosses because it's more cost-efficient to mill a surface flat than to mill several different small bosses within the same flatness as the edges on the bosses leads to reduced tool life. @7:15 I've been taught that fillets at the floor of a pocket can reduce costs if you use the same radius as standard corner radius end mills because the sharp edge on flat end mills breaks and wears a lot easier. What are your thoughts on this?

BRAVO!!!

What's with the shy growling? Otherwise pretty informative. I wouldn't agree with R being 3 times smaller than H though, in most cases You can successfully make it 6 times smaller without compromising milling precision.

Hi Adam, Thank you for the videos, it helps me a lots. I have a question. In case of internal fillet, is it harder if we machine an internal chamfer instead?

great !

Sehr gut

Good info…Wish your “NU VOIS” didn’t run out of batteries… 😬 Seriously!

Asentrik work ka video banaeye

omg thank you bb

Seems you got your axis wrong. CNC mills don't use left handed coordinate systems.

awsome vid, had to mute and use CC.

Vocal Fry!!

That vocal fry

Mandatory for all engineers lol

Zed axis? I didn't notice an Aussie accent.

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.

Great video, but...ribbit lol.

sorry i cant listen to your voice

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

this was a very good video, thx u. but pls stop smoking. its not good for your health =(

Zed. Lol.

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

Why forcing this irritating voice? At times you forgot to force it, it sounds pleasant. Good content, though.

Henry Kissinger voice, hard to listen to.

Your voice seem need cnc cut.

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

Bruh, what the f is going on with your voice

Your voice is very rough

Interesting topic but that voice...it's like someone dragging a rock. Can't stand to listen. I hope it's not throat cancer or some other illness. Hopefully, it's just laziness.

Maybe you can fix your throat with cough medicine, it's kinda hard to listen since you are not teenager anymore.
