Somehow I got carried away by the comments in the last video and decided to sharpen my welding skills trying to rebuild the mill out of steel.
I remade the entire frame out of 40x40x2 steel box and TIG welded it using a technique called winging it. As a known side effect of this technique the frame is not square, straight, coplanar, or any of the required properties for the frame of a machine like this. I solved it by shimming almost everything on it with washers of different thicknesses and a lot of brute force. In the build of the aluminium one almost everything went perfect first try, in this build I had to wrestle with it a lot, way more than I'm capable to show in a single video. The machine is obviously more rigid than the aluminium one and after a lot of fiddling with it, it is surprisingly straight where it counts and seems to even be properly trammed.
As a bonus at the end of the video I decided to obliterate some aluminium and steel with the wrong dull bit and completely wrong feeds and speeds.
As always let me know what you think in the comments.

Check out epoxy granite casting. Its a cool way to make really rigid and strong machine bases without having to pour your own cast iron. You know, when you inevitably decide to make an even bigger machine. 😁

@@ivanmirandawastaken The project and the work are great, thank you for showing that off:) But the video editing? What is that supposed to be? A Rust video in the style of a 12 year old(sorry for that comparison)? Especially when showing work, these quick cuts give the impression of inconsistency instead of suggesting a fluid and professional (and also traceable!) workflow. This creates an absolute feeling of uneasiness in me, even dizziness, which distracts me from your actual art. Putting the focus on the chord accents in the music and connecting that to the video?: I think that's a great idea. I'm a guitarist and at the next concert I'll put a drill-press on the stage and work on the side. It will definitely be great if the audience and I only half concentrate on the essentials! Just my opinion, I'm sure some others like your way of presentation. I place more emphasis on seeing what is being done in a calm, learning-emphasizing, and fluid manner. These ADHD cuts really hurt me to look at. Okay, It doesn't matter, there are plenty of other good machinist channels out there and I didn't want to nag about it. Sorry, I was just shocked! :) P.S.: I watched it to the end ... not that you think ... How about the important stuff? Like tolerances, measurements, parameters of the mill? That wasn't even a topic. Hey and your machinist skills are wonderful. What needs a little love are the teaching and presentation skills. Again, just my opinion and in no way a demanding request. Do what is fun for you, period:)

A few advices from my point of view (and at least 50 or 60 custom build CNCs): 1. Weld using magnetic angle clamps 2. Never ever drill or hammer the base of already mounted rails 3. Use CALIBRATED metal blocks when centering things to be parallel 4. After you think the machine is complete, just pick the dimensions of calibrated object like precision steel ball with CNC precision steel touch probe and then recreate it. If the dimensions of the copied object are not close to the original, then you have a problem

Shoulda filled everything with sand to increase the vibration damping

@nukularpictures 3 жыл бұрын

@Patric Nope sadly that is not true. That is the problem about harmonics. If you hit the right frequency you will get a lot of oscillation even if you take very shallow cuts. And this frame will have a ton of problematic frequencies. Also you can just fill it with sand after it is in position. And if you ever want to move it you can just take the sand out via drain holes. WIth some vibrations sand actually flows quite well.

@kaden56 3 жыл бұрын

@Patric Also shallower cuts also means you are going to only use a fraction of what you should on your cutting tools. You’ll end up with every bit having a dull tip and virtually untouched otherwise, not efficient.

@nukularpictures 3 жыл бұрын

@Patric Yes I am saying that. And I am quite confident. Because if you hit or are close to a resonance of the frame no matter how little energy you put into it the amplitude of the vibration will increase. That is just physics. So often it is a much better alternative to just change the RPM and feed rate to get out of that spot. The problem here is however, that tubes often resonate quite well at a variety of frequencies. Yeah ok. If you go very shallow the dampening of the frame will be enough but at that point I would not call it milling any more. It is rubbing, causing a lot of heat in the workpiece and the tool. Both not ideal at all. If you have to go at such low cutting depth then there is no point of building such a machine. The materials used in this machine, given proper assembly, should be able of milling through aluminium with 10mm depth of cut and a width of 1-1.5mm. If you have to go so slow and shallow to eliminate vibrations the machine is pointless.

@michaelwoodcock9357 3 жыл бұрын

Makes no difference if the spindle is a spaghetti noodle. Besides, sand only adds mass, not rigidity so it's kindof a second rate option in comparison to high performance concrete

It would be interesting to see a shoot out between this and the previous mill you built just to show what you gain from making one this way. Mill that test piece on both mills in both aluminum and steel. Take notes about total machining time for each and compare the quality. Someone suggested you machine the bearing mounting for the ball screws in aluminum to replace the 3D printed PLA parts and make them more rigid. If you do something like this then it would be interesting to see a before and after test to show if it made any noticeable difference in the surface quality. Everyone keeps saying rigidity, rigidity, rigidity, but it would be interesting to see if it makes a huge difference or if it's subtle. The PLA parts are pretty substantial and the material dampens vibrations pretty well. So it would be interesting to see just how much difference there is.

@quelixfenzer5108 3 жыл бұрын

I really like your videos and have been experimenting with diy cnc routers during this pandemic a bit. I recommend using single or dual flute cutters on these high rpm spindles becaust it enables you to take slower deeper passes (good for the steppers) on high rpm (where these spindle motors have good torque) and still take a decent chip per tooth wich is important to reduce friction and extend tool life and have cleaner cuts. Also I recommend to fix the machine to something heavy or even cast a concrete block around the steel frame to dampen vibrations because steel alone is not good at that. Other than that great machine! Keep going and greetings from Germany!

The frame is going to warp over time due to stress in all those welds. Also, the heat of the steppers is going to tranfer into the 3D printed plastic parts. Both not a good idea if you ask me.

@exol511 3 жыл бұрын

Agreed. Not to mention the MGN rails/blocks are not made for the forces which show up in a router/mill and the seals on em are also not going to stop dirt from getting into them, which will drastically reduce the lifetime. The spindle VFD is also not correctly configured if the spindle can be stalled without faulting it out, which is dangerous as there is a chance it burns up.

When using a vice, the area being milled needs to be between the vice surfaces. The overhang flexes and throws off your accuracy. Your frame needs much more bracing under your table as well. The tool pushes down on the x and y axis and there is no support underneath. Even 2 uprights directly under the center of the base will reduce flex by a ton. Ideally, you would make a box around the frame and fill it with a mixture of granite and epoxy. It will give you the strength of a professional machine this way.

I'd box in as much of the open structure as you can with 4 or 5mm sheet steel. It would make the frame a lot more rigid, even if they were only attached with bolts into the frame (Rather than welded in). It would help get rid of some of the tool chatter marks in the work.

Nice job on the video and the build. Definitely look at moving the y motor to the front, put a skin on the machine, and fill with casting cement/epoxy. Make sure to add in a means to bolt it down to help add additional weight too as you may find you want more later. You could also modify your y setup some to add a catch basin in the cement with a drain, so you can make a liquid cooling setup. The Z extension can be tied to the rest of the body with the epoxy cement core and help move the vibration to a much higher frequency to help reduce chatter at lower speeds. Adding a bolted on solid base with a vibration absorbing material will help further, but will also likely bounce the vibrations back to the top of the Z, so if you go that far, you will have to do some tests to find where the sweet spot is. There are some nice accelerometer testers you can get these days to test for vibrations at cheap diy prices due to the Voron push in 3d printing.
