The key of good design is a cooperative work between designer and manufacturer . Some time a simple change in design can make a production a lot easier and chipper . Like designer , you do not have any limits in CAD modeling , but when you start think about manufacturing , that is a totally different world . Good design , think a make a good functional part , but for a reasonable price , because if it is too expensive , who will buy that . I'm the old school , finished my carrier like CNC engineer , but start to work like design engineer . That is the only win-win combination .

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.

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.

@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?
@typhoys2 жыл бұрын
From my experience it is true that bosses are expensive but it is easier and cheaper to achieve flatness for a smaller area
@EricBrummer2 жыл бұрын
If the bottom of your pocket has no impact to your design, you can always call out in the drawing something like "R0.5 MAX, sharp corner allowed." Then the machinist can choose based on what they have and what they think is easiest. On some materials, using a bull nose end mill can be a major tool life saver. As for bosses and flatness you can really get in the weeds on details. Size and thickness of a part matter a lot. Holding flatness in 2 small spots on either end of or across the whole surface of a partrhats 4ft long is going to be difficult. Same thing with thin stuff that is being warped clamped in the vise. Also depending on the amount of material removal the part will change shape as you relieve stress in the material and/or reduce the rigidity by making it thinner while clapped. If the part is smaller, like a fits within the visse, then you can rely on the accuracy of the machine heavily and get a decent flat surface especially if using a fly cutter to cut with a single point. Having discontinuous cuts (tooth cutting then not touching then cutting) is bad for tool life especially carbide but with the bosses shown you might not even have that issue. Face the whole thing first, then relieve around the feet. Although on a small part there's probably no reason to have feet. Much larger stuff the feet help although for anything requiring really tight flatness I'm probably existing grinding anyways in which case I don't think the feet have a major negative impact (and save time on grinding) but I'm far less knowledgeable on grinding.

do note that for threads, you might want to have a larger diameter drilled out on the other side (this can be done on a drill press if it's the only feature) so the screw has some space to go, and that also allows you to specify a single size of fastener, which can be quite a lot of money saved for production (as it's one less part on the assembly line and you can order bigger bulk), and less headache for maintenance. also it allows some wiggle room in fastener size, so if a suppliers offers you a slightly longer screw for cheaper you can switch to this one.

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.
@AdamBender5 жыл бұрын
Good feedback Drew! Yeah bull nose end mills with small corner radius can be great for harder to machine materials like stainless, or lowering stress concentration. Agreed on my undercut drawing, I got a bit lazy with that one, but I was hoping it would get the idea across. T slots and dovetails are two exceptions for undercutting when done correctly. Thanks for the input and watching the video!
