      @@zakquddoos4641 A flexarm would only really be useful for drilling and tapping the faces of the extrusion, not the length of the extrusion; though a flexarm isn't that useful in making the process more efficient. A better solution for the lengths would be a horizontal drill/tap setup, where the extrusion is butted against and endstop and a horizontal stop, while using the table for a vertical stop, for placement, with the spindle on a guide and spring for when drilling and tapping; all you'd need to do is rotate the extrusion to dill and tap the next hole, as each predetermined stop will accurately locate the spindle for the next operation. For the repeated drilling along the face perpendicular to the length, a setup on the drill press can be used, all it needs is a pin for the endstop and a second pin that'll also locate the previously drilled hole to setup for the next hole being drilled, as this is a pretty basic operation. The only use a flexarm would actually provide is a preventative for repetitive strain injury from drilling and tapping each hole with a hand drill.

    A recommendation for bolting down linear rails: they are likely to be much straighter than what you're bolting them to, so rigidly bolting the 2 parts together will warp both parts. Use a stack of Belville washers on each bolt (6 will do, alternating them to face opposite directions) and tighten the bolts up only to the point when the washers are partially compressed; you'll need to use thread lock on the bolts to ensure they don't loosen, but you rails will remain absolutely straight.

    Ivan your an absolute weapon!! I love your builds. As a CNC machinist myself I really appreciate what you do and live your antics. You keep saying your machining skills need work. May I suggest the following:
    Instead of IPA use a petroleum jelly or kerosene as a cutting lubricant for Aluminium (it's what we use in industry)
    When setting your toolpaths try to do it in such a way that you maintain a constant chip load as this will give you good performance from your cutting tools.
    If the material is fraying like it is, it's because the speed is to high and it is cold welding the chips back onto your workpiece as the tool is bringing the chips back around. Imagine metal cutting as more of a sheering than a cutting action, like scraping a knife along a block of butter rather than slicing straight down through it.
    You are essentially trying to force the material apart, the softer the metal the gummier and less likely to separate it is, excluding self lubricating materials such as bronzes and brasses.
    Have a look at the Vm data on your cutters and they will have operating ranges for speeds and feeds, going below is just as bad as going above. Look at your tool and see what it is telling you. Chipping means too high a chip load, a built up edge on your tool means to fast or the wrong coolant/lubricant, carbide tooling when it's sharp has a dull edge feel, when it feels sharp it's dull.
    Generally when cutting dry I reduce the speeds and feeds by about 50% to prevent problems. For demo prices and trial cuts use a free cutting brass as it almost never clogs the tooling.
    Ok hope this helps a little. Keep up the outstanding work!!

    1 it you fill the aluminum extension with epoxy granite that will help with the vibration that will increase The CNC performance .
    2 add a support beam at the front of the xy carriage that will make the Bed more flat .
    3 Mill the connecting surfaces flat ( where the Linear rail Is mounted )
    4 add steel plates in the z axis of the spindles.
    5 buy a metal spindles not a wood spindle like you are using the Will improve the tolerance and will last longer.

    This is awesome! However, I will say, as someone who owns an actual 3 axis CNC knee mill, you really should have put the Z axis movent in the knee....while yes, you can move the knee up and down for larger parts, but having such a limited z travel (as I do with an automated quill), it's extremely limiting with respect to cutter length and retract/clearance heights...very annoying....the next thing I do to mine is going to be put a ball screw in the knee, add two gas struts to offset the weight, and cut a hole in the casting to run a belt drive go the top of the screw....

    You can save a lot of time if you first make roughing passes with a flat end mill and then move to a ball end mill (with a much faster feed speed). Also end mills are much more efficient at working with their sides, avoid milling downwards at all costs. The surface finishes will be much better, you will be able to use faster feeds, you will significantly reduce the chances of the end mill clogging up (and breaking) plus the tool life will be longer. You made yourself quiet a tool, really interested to see what you will make with it, good luck!

    WOW Ivan, this is a really crazy build. I have to tip my hat.

    1. You don't need those monster Steppers, in fact, for what you paid for those, you could have gotten Closed loop Hybrids that hold their position.
    2. Rigidity Rigidity Rigidity!!! There's a reason your taking teeny tiny baby cuts on your aluminum (Which is why you really don't need those Monster Steppers). A good project for your new knee mill could be desiging and machining more Aluminum parts to replace your 3D printed parts. I LOVE YOUR DESIGN, but maybe make it a work in progress and show how you stiffin it up and prove it by making deeper cuts.

    Nice CNC machine build. Try a slightly smaller ripper bit for rough cuts, then the right size end mill for the finishing pass; that's what I use now and it eats through aluminium even with only a 150W spindle motor and finishes nicely without changing the G-Code. Also, you may want to look at getting a septic tank aeration pump instead of a compressor to blow the chips away, I tried this and it works really well, plus is only just above 30dB and will run continuously for years.

    Nice work btw. You’ve shown people they can build on a budget to get started in CNC.

    You would see the benefit mixing material types quickly and so would your viewers. As I mentioned earlier 3d printing lost wax into casting of parts.
    You have the tools and knowledge to evolve. I bet if you went this route it would be a matter of time before you could compile all your videos into an evolution of DIY to industrial machinery.
    This is what guys like myself have done to get where I am. Ive built my own industrial machine little over a year ago and it’s sitting in storage waiting to be wired up soon as I find the space i can use it.

Can the CAD software make use of that functionality? When reading up on CNC mills the fourth axis is always referred to as the A-axis, and is defined as having the workpiece rotating around the X-axis. I seems it would take a lot of tinkering to make the controller and cad software understand what to do with a fourth axis that tilts the head and has quite limited movement.

    WD40 is a pretty good "coolant/lubricant" for aluminum if you're just getting started and looking for something you can use that you have laying around the house. For the half sphere, ball end mills do a much better job with light cuts, so consider using a roughing operation (that leaves a little layer of stock) with a straight end mill before using the ball end. This would also be MUCH faster. Great videos!

    @berendlucasvanderweide 3 роки тому

    Nice work! It's only a matter of time before this machine makes its own upgrades. The thing with any form of potential difference between the machine and the rotating spindle/lineair rails is that it can cause the bearing to go bad quickly. The ball spotwelds itself into the race of the bearing while running, deforming the ball/race slightly, causing it run less smooth. And this goes for all the parts with bearings and races, so lineair rails with steel rails/carriages also suffer from this. With non conductive bearings (ceramic) this doesn't happen to the spindle. Some spindles have a drag-contact on the rotor to the spindle. Using thick wires to ground everything (especially on the rails/carriages when they are isolated from each other by plastic parts). Don't put any ground in series, just link them all to 1 central point on the machine.

    Ivan!!!! Please look into Epoxy Granite. I believe that if you use your plans as a skeleton and cover it with epoxy granite, this mill would outperform any cheap Chinese mill and maybe even be as good as a stand mill. But this is a revolutionary project non less... Keep up the good work.

    Such an awesome build! You should try to avoid slotting with your endmills as much as possible, it's horrible for surface finish and chip evacuation/tool life. Also on the hemispheres you could try running a roughing pass with a sharp corner endmill, or one with a small radius. Then come in for a finishing pass with the ball nose.

    Great build, also there is loose screw on Z at 15:34 - you can see the washer dancing :-)

      I missed the screw, but at 18:35 the plastic plate the Z ball screw is attached to has a nice flex moment when presumably homing. I feel like I should check all of the XX:33s and XX:36s to see if there is a series.

    As cool of a project as this is you could buy an actual milling machine for the cost of the profiles!
    I have been through several iterations of milling machines in the past few years and in the long run I just ended up buying an industrial milling machine and have finally found my machining happy place. I had a few table top mills that I converted that did nice work but ultimately I wanted to make many big parts and went all in. The table top mill conversion is an excellent route for someone looking to get somewhat serious about making aluminum parts.
    That being said, I have scratch built machines and understand they joy of making the machine itself. This is kind of a tedious route to take however.

    Ivan, fantastic video as always. As a machinist and engineer, as soon as I saw the spark on the aluminum I thought 'Oh something shorted....' I can't believe that spindle isn't grounded though. Not sure I would be comfortable using that in the long run but your addition of a grounding wire is certainly a good improvement!

    Make a floating drill, like a drill press but the drill is a household drill and on an arm that lets it float freely in X and Y, Z is a lever like on a drill press. That would make the drill perpendicular to the work surface all the time but give you all the freedom of having a manual drill, because you can remove it from the holder

    Hi. This is an amazing project! Maybe you already solved it, but on the minute 18:35 when the Z axis stops, is can be seen as the screw support deflects a bit. Could be worth checking.

    I would like to see the cut quality in aluminum using the single flute, nice slow feed cutting strait lines(the wall finish). It doesn't sound like there is a ton of vibration which seems impossible given the wrong linear rails, hollow aluminum and plastic holding it all together. I'd say I'm most impressed by the spindle but not the grounding of said spindle.

    When machining aluminium try coating the cutter with inox Teflon spray and also use it during the machining to cool the cutter. It will also help aluminium from sticking to some cutters

    Cool build! Gave me lots of ideas 😍
    2 things tho: correct me if I'm wrong but it seems like you did not put in any proper bearings to take up the axial thrust of the lead screws (slack free and stiff)
    2.: You could use a couple hundred KGS of weight on body of the machine to make it more sturdy and eat up vibrations

    I love the enthusiasm. Spindle and controller seem nice, that's proper hardware. I'm sure this will be a useful machine for some hobby projects. However I wouldn't trust this thing to hold smaller than 0.2mm tolerances. If it can achieve even that.

      I'm more worried about chatter. Seeing how knee mills have to be extremely stiff I wonder how bolted together aluminum profiles are going to stand up to the stress.

    i have thought lots about a 3d printed milling machine.... as you do... one thing i keep coming back to is 3d printing a shell/mold for the mill in to which you pour epoxy granite (after getting everything as square and precise as possible). lock that precision in and get it a lot more rigid. i think you should be able to get sand for free and maybe a few hundred euros of epoxy.... ehhh maybe? for youtube science?
