Yep! 😏

@@carbide3d do you guys make a water jet attachment so I can cut stainless steel?

A factually incorrect statement. That machine is decidedly less rigid than a Shapeoko.

@@carbide3d 😆😆😳😳 have you ever used one? Ever interfaced with it??

He said it in the video.

It’s all about them feeds and speed.

Just added in the description.

Not really. My depth of cut isn't exceeding the thickness of the material, and features like the flange could not be machined with something on top. For thin gauge sheet metal that might be more appropriate.

He said it took 3 hours if you watch the video

@@grizzlymetalworks8867 I did watch the video, my bad missed it.

What? The tolerance is decided by the print. Are you asking how accurate the machine is when cutting SS?

@@kw2519 my apologies, I wasn't clear. I want to cnc a block of steel or aluminum 6061 but the wall thickness is about 0.5mm to 1mm but the wall height is about 7 mm. Wanted to know if that would be possible with cnc machining. I am trying to learn about cnc machining before buying one.

@@Verton_D Ok, I got you lol Big difference between steel, stainless steel and aluminum when it comes to milling. But the main thing is how tall and thin that wall is. Is there anyway to support the side opposite of where you’re cutting? Because I’d imagine that wall will want to vibrate like crazy. It’s less about whether you can make that feature and whether or not it’s going to chatter like crazy. It is likely that the wall will be thinner or thicker in the middle as that is where it will be able to flex the most. Anything is possible, if you were ramp down as you mill the perimeter, that would put some of the cutting force down instead of to the side, which would help keep the chatter to a minimum. But you wouldn’t really be able to go back for a clean up pass as you’ve milled all your support away. The diameter of your tool relative to its length will also play a role in how much flex happens. But there’s only one way to know, to try it.

The Nomad is definitely stiffer as it has beefier linear rails than the taigs extrusion and the gantry style helps that stiffness . Also, this is a "mill in a box" and totally self contained with a tool height setter and their software designed specify for it, where the Taig is open with steppers and wiring totally exposed and pretty bare bones with a lot of it up to you to decide. Quality of the Nomad is excellent and no worries about chips all over the garage. You can literally use this on your desk. I'd go nomad over Taig any day. Oh plus, Taigs are really designed for micro parts and will struggle with larger parts but are definitely accurate little guys. This has a bit more capacity in that respect, but really two different machines for different purposes.

The bit is cutting in the correct direction, he is conventional milling instead of climb milling though. Is that what you mean by "backwards?" This little toy is not near rigid enough for climb milling in stainless.

Yeah I would not do climb milling on that router unless you have a poly-carbonate riot shield in front of you..ha ha.

It's our standard router that we ship with the Shapeoko, the creatively named: Carbide Compact Router.

I'd imagine minor variations in the x/y travels. I'm not as familiar with CNCs, but in 3D printing things like gears they can to come out just slightly oval for I believe that reason.

@@ElectroPulse93 there is no Y axis on a CNC lathe because the stock rotates. It will be perfectly round in the end.

@@ChristophPech Oh, my bad, I missed the word "lathe" in your comment.

I am not a cnc guy, yet. But the forum has qr codes done on shapeoko that are read easily even from reverse cutting it into a wax stamp to be read later. So yes, it seems precise enough.

I sort of default to 0.01" optimal load for metals, and will make small adjustments based on what I observe. I also looked at tool manufacturers recommendations for chip load, and S&F, then reduced depth of cut to account for reduced rigidity. Mostly cutting by ear, but also looking at tool wear to see if the S&F are sustainable. Vibration will dramatically reduce life expectancy of tools. -W

You know that guy? I wish he would share more videos of his projects.

Which is easiest to machine?

@@Audio_Simon Butter (since you didn't specifically list your choice of metals...)

@@RichardCournoyer Context dude! Stainless steel grades.

Simon A Only the 303 Grade. Why? Because it’s only grade the Free Machining. We could go into the material science as to why, or you can just trust a guy with over 40 years of experience.

they are very large. He is specifically referring to the desktop CNC machines that Carbide 3d sells.

Yes, but they're huge if you want one that is decent. Nobody that I know of makes a decent desktop CNC lathe.

He meant mill vs. lathe. Not literally "lathes cannot be CNCs" I'm sure most caught that, so I'm assuming you're being pedantic.

@@davidk8893 no, outside of a Taig or Sherline for micro machining, but getting an x2 or x3/grizzly and converting it is absolutely viable and it's a fun project. Plus, you can get damn decent results.

@@shirothehero0609 you're assuming and calling names, not nice.

@@asherdie calling names? What name did I call you? Do you even understand what the word pedantic means? Don't be so fragile. Nothing was said that was even remotely close to calling you a 'name'. And it's PAINFULLY obvious that's precisely what he meant. Winston has been around CNC long enough to understand that lathes are perfectly capable of being CNCd. Anyone that is as deep into CNC as he is understands that.

2.38mm

I can Google it, but it means nothing when watching the video unless I stop to find out.

You try it and post the results

I checked your channel, for some reason none of your machining videos are showing up

I assume he did this because using an adaptive tool path like he did puts much less strain on the endmill and cnc. If he used a countor toolpath to just cut all around the wheel the endmill would be plunging straight into the stock and would be cutting on both sides of the endmill. on hobby machines, I always try to avoid slotting because you are more likely to break an endmill.

Slotting sucks, especially in stainless. Avoid it when you can. It's a good way to get your tool to glow red and then break. Ask me how I know.

thanks for the explanation guys. much appreciated

He explicitly says that this is purely to demonstrate that you can machine stainless steel on a desktop CNC mill. The wheel was just a random item he chose to demonstrate. He even says that you would want to use a lathe to make a wheel in a normal setting, but this is just to demonstrate the concept. Watch the video completely before you make nitpicky comments.

@@davidk8893 The point of my comment (which you seemingly completely missed) was, the equipment he used is not a "CNC", there is no such equipment - it must be a "CNC ... something" CNC means "Computer Numerical Control" so him saying, "I am going to machine this on my computer numerical control" is just plain wrong. It is like me saying, "I have a red." when I should have said, "I have a red car." It is a nonsensical, lazy and inaccurate statement. He was using a "CNC router", how hard can it be to speak properly?

​@@poruatokin No, I understood your comment perfectly. It's an unnecessary nit-picky complaint about a gramatical error that does not significantly detract from the understandability of the content. I don't suppose you say "laptop computer" every single time you're referring to your laptop? Or "motor car" rather than car? How am I supposed to know you don't mean "train car" or "bumper car" or "flying car"? The tiniest little bit of context tells me that you mean a normal motor car. Shortening the names of things is a common practice in the English language. If two people are talking about cars, and one person says "I have a 2004 Camaro, how about you?" the other person may reply "Oh, I have a 2005." What, do you expect them to say "Oh, I have a 2005 Chevrolet Camaro" instead? No, because it's unnecessary. The context allows for the omission of words, regardless of if they are grammatically correct or not. The same thing applies to "desktop CNC". Sure, it may not be technically grammatically correct, but if you got the point of the sentence, then why bother complaining about it? He says "desktop CNC". How many desktop CNC lathes have you seen lately? Few, if any. The only real CNC machines that you see on a desktop are typically routers or mills. And that's the subject of this video. (before you decide to "educate" me, I know 3d printers are CNC machines that fit on desktops. However, you don't machine things with 3D printers, and nobody calls them CNC 3d printers anyway, so there is no reason to think that he was talking about that either.)
