00:00 Introduction. We'll go over which design aspects of CNC machining are explained in this video.
0:42 Design restrictions. It's important to know the design restrictions of CNC machine before designing parts. Therefore we'll cover tool geometry, tool access, workpiece stiffness, tool stiffness and work holding.
3:13 Cavity depths. Moving on to design rules, starting with cavity depth. You'll learn how to design cavity depths with important design rules in mind.
3:40 Internal edges. Learn how to design internal edges with CNC design rules in mind.
4:30 Thin walls. Learn how to design thin walls with CNC design rules in mind.
5:07 Holes. Learn how to design holes with CNC design rules in mind.
6:05 Threads. Learn how to design threads with CNC design rules in mind.
6:42 Tall features. Learn how to design tall features with CNC design rules in mind.
7:01 Small features. Learn how to design small features with CNC design rules in mind.
7:27 Tolerances. Learn how tolerances should be defined.
7:47 Maximum part size. Learn about the recommended part sizes when designing for CNC machining.
8:20 Undercuts. We'll discuss when to use undercuts and how to design them.
9:11 Undercut clearance. Finally, you'll learn how to properly add undercut clearance to your design.

This is actually a pretty good channel. Respect for content mates
Thanks! :)

Great video. Everything explained in crisp manner. Love it !!!
Good info.
Thank you, 3D Hubs.
About to plunge into the CNC world at the RC scale... Finally a video that lays out what my newbiebrain kept wrestling with, accuracy, precision, tolerances, tool and machining capabilities.
...like how is the tool made to cut inside/outside the line?
- I quickly saw the need to create a combination of 2.5D sub pieces to build a 3D final object that the limitations of the tools prohibits as a one block creation.
- I also dreamed of repositioning(he mentioned), as I would have to do that to design pieces that are bigger than the machine can handle.
- One thing I also have thought of is how to get an inside corner to be square.
basically, a square piece can be made to fit inside a round one... tricky!
... This will work to a maximum precision as per the smallest tool that can be used,
and given the thickness of the surrounding material requirement.
so, run the small tool in a second pass, past the corner design until all the corner material
is removed and the small tool is driven by a distance of its radius past the actual
corner desired... that will leave an indentation in the corner that is 1/2 the width of the
small tool(clover leaf), and leave the inside fitting piece the space it needs to mesh squarely.
... or if possible, round the corner of the inside fitting piece to match the
original outside piece rounded corner.
... or use another sawing/shaving tool to clean the corner, a specialized attachment
rotated in position on the same head.
This Channel is awesome
This is awesome.
Great video! Thanks a lot :)
Welcome! Glad you liked it.
Thank you
Great tips)) Thanks a lot ))
Happy to help!
How do you only have 3.8k subs, very well done video man. Thank you!
Thanks, Chris!
THANKS
Good work!!! We also have rich experience in sheet metal fab, we are a strong manufacturer in China, with high quality and competitive price.
3:22, you meant depth < 4 x Diameter, or depth < 4 x Length. Thanks, great information and videos.
good
Hi, great video! I just didn't understand one part-when you were recommending using a T-Bone undercut when 90 degrees corner is required. Could you please elaborate on what you mean by that?
I didn't understand this either.
I believe this was an error. What you can do is design in a relief pocket where the fillet eats into the corner. Slightly hard to explain. Only thing on this video I found that wasn’t very accurate.
nice contents
hope you keep update :)
Thanks! We are definitely keeping it up :) Subscribe if you haven't yet to not miss anything!

Hey mate, great information. Next time, please either have the music on the whole time or none as it seems repetitive when the same sound plays, maybe even make it a bit softer :) you’ve got a sub and a like from me :)
Hey Aaron, thanks for the feedback. We will definitely take it into account. We want the videos to be informative and enjoyable to watch :) And thanks for subscribing and liking the video!
3D Hubs no worries mate, keep up the great work!
DO you need CNC machining center?
The maximum depth of holes you recommend is 4x the diamater. OK. But then why do you go on to say 10x is typical? What does that even mean? Isn't that 2.5x higher than the maximum you recommend? That doesn't sound typical.
Glad I'm not the only one lost in the sauce here
Yeah I just spotted that.... I think he's recommending 4x Tool diameter for hole depth for best results, but says 10x is typical and 40x is feasible. EDIT: yeah doesn't make sense. I just researched it and anything over 5x and you need to use peck drilling to remove swarf and then 7x you need to use special parabolic drills. You can go to 20x with gun drills. There were other errors in this video as well.

@@aries6776What is feasible is totally dependent on whether or not you have high pressure, through-spindle-coolant and through-tool coolant. 40x is not entirely uncommon these days in some applications.

Great video but that drill bit image is a wood bit
Hi Andy, you are totally right. Thanks for the feedback! We try to make these videos as informative and factual as possible but unfortunately we don't always get it 100% right. Next time we'll have an even better look :)
You need to cut down on the hand movements. I know it's a psychological trick to attract attention, but I can't stand too much of it.
