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!

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?

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.

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.

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 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?
@user-tf1oo9rj6u6 ай бұрын
It will work, you can even make 'boards' of this stuff and bolt them vs a whole pour, but that is reducing how well they work. Large machines will typically fill their box beams with cement or something like this. the better the interface to the alu the better this will work, so you might want to use something to fill any gaps, like a thin layer of rhino liner or caulk, then clamp it tight, so it can absorb those vibrations and send them into the absorption material.

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.

Your high sand version must not have much mass/weight compared to granite or lead ballast. Also, bolting any machine to the concrete floor is THE BEST vibration prevention. Sorry, but I think you're off on a wild, expensive, OCD fantasy here.

Outstanding content. In 2 part polymers with fillers, I have always been told you need to mix part a and b together then mix in the filler to prevent differential adsorption of one part in the filler (sand in your case) which would inhibit a full cure. You're method seems nice since you're not rushed by the curing epoxy during mixing. Did you notice any softness in the end product?
