I'm curious on how they account for the diameter of the tool shrinking

[@flyfaen1]

"Simple", measure tool diameter offset when the tool is cooled, or if the need for precision is extreme, a tool offset chart vs. temperature, and use IR based dynamic tool temperature offset...

[@tweetertx02]

I would think the tool would stay at a constant temperature during cutting operation. I don’t think your going to get much thermal shrinking on carbide or ceramic inserts. Tool holder might shrink a bit but you can run test to figure that out.

[@elijahwalton1766]

@@flyfaen1 yeah measuring the tool at its coolest state would probably work and for bearing fits and such you could have a offset screen that measures tool temperature and runs it through a graph [dia. vs temp] and account for change

[@elonquemattheson6151]

[@Mtaalas]

Lubrication qualities of "coolant" should not be underestimated here. It helps with chip evacuation. Running dry you don't get those benefits even if you do get lower temperatures. Also, the whole machine has to be built for the cryogenic coolant since the temperature is so low and affects more than just the cutting edge, like bearings and other parts that refrigerant runs through to get to the cutting edges... so might not be cheap.

to all scientist from the comment section worrying about thermal expansion from the cold air, its not so much different from using water or any liquid based coolant, the Bit is not a super conductor of temperature so there's no way that it could affect the precision.

Just an explanation for all of you cryogenic cooling is used for titanium and titanium alloys. Thermal expansion doesn't need to be considered because this is only used for roughing and drilling, and tungsten carbide won't get brittle when cooled down.

3D printing has been around for 40+ years. It still has all of the same issues that it's always had. It's slow and inaccurate.

[@FireGodSpeed]

@@brandons9138 inaccurate? no, slow ok i could give you that. The side of 3D printing is that you can make parts with almost 0 effort which would be IMPOSSIBLE to machine (you could still cast them obviously but you also have limits to that, if you use shell casting or investment, you have to make sandcores either with printing or a core box etc etc)

[@brandons9138]

​​​@@FireGodSpeed3D printing is wildly inaccurate compared to machining. 3D printing has its uses, but it's not a replacement for machining. Porsche and Trumpf are 3d printing pistons for Porsche's racing team. Just about every surface on them has to be machines prior to use because they can't get the tolerance/form or surface finish they need. There will need to be a paradigm shift in how 3D printing is done before it even comes close to machining. 3D printers are one trick ponies. If I have a tight tolerance hole on a part in a machine tool I have several options on how to achieve that hole/tolerance. On a 3D printer that is not the case. Once a mill or lathe is set up it'll run lights out with minimal human intervention. At my shop we have a robot loaded 5 axis mill that will run for 48 hours non stop. We could do more, but our material staging area is only so big.

[@FireGodSpeed]

@@brandons9138 ofc its not even close to accurate compared to machining i never said that lol. I just said its not "inaccurate" it really depends on part and application. Some stuff does not NEED to be machined they can stay as rough as they come out. Taking a piston as an example i mean come on you serious. Ofc you can't 3D print a fucking piston to spec when it rides in a honed bore are you for real? I did some googling on the tolerances of 3D printing and my guy.. "For well-designed parts, tolerances of +0.003 in. (0.076mm) plus 0.1% of nominal length can typically be achieved. Note that tolerances may change depending on part geometry." (+-0.1mm max aka 4thou+- MAX) That's 3thou accuracy at best. "inaccurate"? Compared to a Cast part that's accurate af. We have a 5 axis mill too that sometimes runs up to 60 hours at times, no clue why you even brought that up lol. And here we go with the "yes that's very inaccurate, i machine parts to microscopic level, not even the best machines can detect the precision i do" I make molds btw and i say +-1 thou for most stuff pff. its not that deep. (Piston and cylinder need a MINIMUM of 2 thou clearance, can go up to 6thou) so not even that is that deep my guy.

Meaning...you.may not need to use lubricant or cooling, hense reducing the possibility of contaminating the water supply of your area, or inhaling it...but, you need to compress and liquify Nitrogen (or whatever they use) consuming huge loads of electricity, produced (usually) with efficient, but still environmentally hazardous, ways.
