As an engineer who works in industrial control systems and automation (30+ years) this is a fair effort for a non-engineer and you have done something that few do - LEARN. Good pick up on the linear bearings it was the first thing I noticed, but then I do know why people use circular shaft linear bearings($$$). The linear rails are way more accurate and more importantly handle larger loads for their size. HOWEVER those rails are heavy and you can get into a lot of trouble on vertical axis if you are not careful (see below). Before we get to vertical axis we need to cover an issue that confounds fully qualified engineers - *INERTIA RATIOS.* This is incredibly important with motion control if you want to get any sort of accuracy. All mechanical engineers learn about it in their very first dynamics class. I know because I lectured and tutored that class as a postgrad. *Its also something all mechanical engineers immediately FORGET after that class and sooner or later bites them.* To ACCELERATE & DECELERATE anything requires force and in the case of an electric motor (servo, stepper,... etc) that is most commonly a TORQUE force. Yes I know about linear servos, but the same thing with inertia still applies. FIRST (and super important) we are *NOT* talking about static loads we are talking about *DYNAMIC LOADS* so it involves INERTIA of the system. There is the inertia of the motor and the inertia of what its driving. Under static conditions the torque required to hold a load or start moving it is simply the gear ratio *BUT under acceleration and deceleration its a function of the gear ratio and the INERTIA RATIO SQUARED. So if you double the mass of the load on a motion control system you require 4 times the motor torque to accelerate and decelerate the same. THIS IS THE CRITICAL POINT FOR ALL YOU AMATEUR CNCers KEEP YOUR INERTIA RATIOS BELOW 10:1 as in the inertia of the load must not be more than 10 times that of the motor. Its even better if you can keep it below 5:1 and best around 3:1. Consider that at 5:1 you are 4 times better of than 10:1 and 3:1 is more that 10 times better than 10:1. Think of it this way. Imagine if you have a light but reasonably powerful car and you hook up a large heavy trailer. Sure the car has enough grunt to pull the trailer, but what happens if you try and brake hard at speed? The Inertia of the trailer just dominates the car and pushes the car past any limit it might have or just jackknifes it. In general you will find the inertia for a motor in the catalogue or manual. For all the other items in the system you will also find that data in the catalogue or manual. Companies like Siemens, Schneider and others all used to produce inertia calculators with their catalogues already in them. If you use one of there calculators and it wont let you enter you motors particular stats just use the motor out of their catalogue that is closest. On your vertical axis its incredibly important to get mass out of the moving parts. There's a terrible tendency for mechanical engineers to put the linear rails on the moving part. I'm pretty certain you did what I'd recommend in having the linear shafts on the fixed side. The problem with vertical axis is that you are fighting gravity as well as inertia. The other thing to consider is filling the base with epoxy and granite to add dampening mass. There is a continual issue with all motion control systems. If they are very light they have less dampening and from just the motor vibrations you can get all sorts of accuracy issue because the whole thing is shaking. This is why milling machines, lathes and CNC machining centres are made from bag castings. Its not that the castings are cheap its simply mass damping. There are videos here on YT of guys who have used epoxy and crushed granite to get that effect.

A column machine is the most rigid, a fixed gantry is the next best than a moving gantry. This is because a column only has one moving axis attached to the spindle, the fixed gantry has 2 and a gantry has all its axis’s moving the spindle. The con of a column of fixed gantry is not so much about moving the part but more to do with travels. A fixed gantry need to be twice as big as a moving gantry for the same travels. A column is even bigger. So I guess it comes down to what you want to make with your machine.

Concerning Gantry Style. I was an early CNC PCB Drill and Router Programmer/Operator in my first career (late 70s-early 80s). I programmed and ran several different styles of machines. I think the best compromise between rigidity and size is the Moving Table, where the machine is wider than it is deep, the table moves Front Rear, on the shorter axis, and the spindle(s) move Left Right, on the longer axis. All the fastest/most accurate multi-spindle machines used this format. It also provides the best operator access to the workpiece.

I've been developing 3-axis CAM software for hobby/DIY for signs/engravings/art over the last 5-6 years now with my eye on 5-axis toolpath generation just about the entire time as a potential future CAM software project. It never occurred to me that G-code won't necessarily be able to know ahead of time the tool offset (i.e. cutter length, or even just how far the cutter tip is sticking out from the axes of rotation). Granted, not all 5-axis machines are the same as the setup you came up with. The workpiece can be rotated on one, or both, axes. These are things I hadn't really thought about (I figured I'd figure everything out when the time came). Anyway, thanks for sharing, gave me a few more things to think about while I wrap up my 3-axis CAM software.

That's awesome! Are you working with BRep data structures or mesh modelling? I think I could manage to do something with mesh CAM, but BRep remains beyond my understanding for now, as much as I'd love to build my own. When making your 5 axis CAM (if you do), only the post processor will need to know the tool stickout relative to the axes of rotation, the CAM shouldn't need to concern itself with that. Or in the case of a trunnion style machine, the tool stickout is irrelevant and it's all about having either the post processor or the CNC controller itself know the location of the work origin relative to the axes of ration. Ideally the controller would do it on the fly, hence the TCP functionality mentioned. Care to share the name of your 3 axis CAM software?

Definitely interesting. Intuitively I think the machine would need inverse kinematics as J6 robot arms do and it's the machine's job to know positions with multiple tool frame offsets that can stack. Experience wise the machines are dumb/smart however you look at it and 'should' go to whatever position you tell it to go to and the CAM side should just generate the toolpaths.

@@machsuper I went with an entirely novel approach for my CAM software, everything is heightmap based - you design your project by loading/creating multiple layers that you blend together to form your project's composition and then I generate toolpaths off of that, performing a sort of Minkowski sum of the heightmap and the cutter's geometry to produce the actual manifold that the center tip of the tool should move over. There are a dozen different toolpath types and only the 3D Contouring toolpaths operate that way, the 2D/2.5D toolpaths generate a series of contours for offset milling, trochoidal milling, profiling, etc... For 5-axis I am thinking the best way to go is to generate a sparse distance field of the 3D geometry to be cut, and toolpathing would operate on that distance field to determine the best way to approach the workpiece. Eventually I wanted to take it a step further and invent a process that lets you just slap any old chunk of material into a machine, it scans it, and then with a pre-defined set of tools it goes ahead and dynamically mills out a target model on-the-fly - sorta automate out the need for CNC expertise entirely. PS: my 3-axis sign/engraving CAM software is called PixelCNC.

I wonder if the ESS/Mach 4 problems are due to the fact that Mach 4 is designed in the US where the axes are all about moving the part, not the tool, i.e., 5th-axis trunnions. I can tell you as someone who has designed and built a fixed-gantry CNC machine and used moving gantry machines, you are partly right about the ease of making the table. The challenge is in squaring the table to the gantry since there is so much space between. Not impossible, just more tedious and/or it requires tools that are less common. (Who owns a 1m square?) It also increases the rigidity of the gantry, and typically allows for faster movements. Very cool that you identified the problems in your design. Even more so that you shared it to help others avoid the same mistakes!

That's some impressive work you've done. I'm happy to see someone taking interest in the mechanics for a CNC machine, my self being a senior mechanical designer. I am designing a 3-axis router or rather portal milling machine and i have come up with a design somewhat similar to your concept. If you want to I can share some of my solutions. My focus has been to make a very rigid machine for milling steel and hopefully also hardened steel. Another aim I have is to make the machines outer dimensions small in relation to the work area. I believe that the solution that you call "moving bridge" is the most promising one. Choice of bearings and placement of ball screws is essential and using twin ball screws is the way to go for both Y and Z-axis. The thrust bearings and the homing sensors are also of big importance if you want to achieve high precision. I was also impressed by your approach to the project planning, working the last 30 years with product development I have taken an interest in conceptual work and how to manage a project. Please let me know if you are interested in exchanging some ideas, I think I could benefit from it too since I'm not so good at software and electronics.

8:05 Can you elaborate on what's wrong with the round SBR rails? I thought they were the superior design aside from being heavier and taking more space. The ability to adjust preload on the bearings with set screws is a brilliant way to get high precision while keeping the cost down. MGN rails have to be perfect from the get-go or else they're useless. The ones I bought were all over the place. By mixing and matching the rails and slider blocks I was able to get them all usable, but if you weren't buying a lot all at once it would be a total crap shoot, whereas SBR rails can always be adjusted. And adjusted again as they wear. I've only used SBR for the Z axis on a 3D printer, but they feel solid enough for a router.

Two major negatives with round rail.... One is that the rail support is a tee so that means the bearing is 'open" which allows a lot of flex. Another is that the ball bearings are round and the rail is round so you get high point contact loading. Profile rails are, well, profiled. The bearing surface is curved to 'fit' the round bearing. This allows for more preload and therefore much more rigidity. They are also 4-way equal load rated which a 'c' shaped open round bearing can never be. There's really no comparison. If you had to mix and match rail and carriages then you bought knockoffs or just low quality. Or the mounting conditons weren't adequate.

*From a former mechanical engineer:* Round tube is only better at rotation _as a single member_ and box beams are still pretty good at that. I have shifted from engineering to working on industrial machinery for a living - most machines don't use round tubes. They are much more hassle to mount and align everything properly vs just slightly upsizing and using box/rect beams, and they aren't single member designs. When trying to resist torque, depth is the 1st most important factor. A piece of paper can be bent/twisted easily. To some degree, widening the paper will help resist, but simply making the paper thicker does far more. And if you think of cardboard, it maximizes this effect for minimal weight by concentrating the material on the outsides, then linking them together with an approximately triangular grid. The thin sheets by their selves aren't strong in that way. The corrugation layer isn't much stronger either (look at how corrugated roofs can collapse). But once they are tied together as a unit, they become extremely strong for the weight. A box beam with internal triangulation will be very strong. Also, 3 box beams in an approximately triangular arrangement plus a bunch of gussets will also be very strong, usually much more twist and flex resistant than just 2 heavier box beams. I notice you didn't mention racking. That is another reason why extending bearing spans is important. As far as wide vs narrow spanning, you are correct, though it may make for a much more compact machine. When you consider that the most effective control on flex is wide bearing spans + rigidity of members, you already want as wide a bearing span for the gantry as possible (really for any of the axies). Being slightly longer depth is preferable in most shop circumstances vs making an already long machine even longer. & When you think about the practicality of doing that, going for as heavy rails and screws as you can afford, cost for longer screws and rails shoots up exponentially. But then all the gantry itself gets more expensive and heavier if it's longer and may need bigger motors, etc. Decide where to spend your money. For a home garage, I really like the idea of a wide spanned machine that offers the option to feed sheets through. If you imagine cutting a 5x8 sheet (or a rectangular shape like a custom door), it is more steps, but *you could use a much smaller machine if it's spanned the wide way and cut & move in several stages. A short span machine would require the _short direction_ to be at least 5ft wide + the rails etc. A wide spanned machine would only require the wide direction to be 5ft+rails etc. That means walking space around both ends of the machine, except when cutting long sheets. That's a win for a home shop, imo, but if you are cutting large sheets all the time, then just make a bigger machine and avoid the hassle of cutting and moving stages. Back to rigidity concepts: when mounting the axis on the beam, you want the rails as far apart as possible, so they resist tip flex perpendicular to the beam. There is the possibility of going with rack and pinion for a big cost savings. If you want less backlash, helical gears are an option. If you do rack and pinion, I highly recommend mounting them facing down, so chips & stuff fall out of them rather than in to them. If you have vibration problems, fixing rigidity is the best solution. After that the common cheap way to deal with that is filling sections of the gantry with cement (at the cost of weight). Cast material is also much better at dealing with vibration (scatter & absorb effect), but not practical for a diy system.

I thought long and hard about the design of my CNC before I built it, and addressed all of the issues you spoke about. But it wasn't without a lot of time in SketchUp and significant discussions with a friend about the pros and cons of each design. I was looking for something different to the well worn path, and I hadn't seen anything like what I come up with (8 years ago). The only significant difference between yours and mine is that I boxed the the X axis gantry in to make it more rigid. It trades view for stability but it is one I am willing to make. Looks like you're just down the road from me.

It’s very easy to end up spending many many hours thinking about the design, isn’t it? I block out the essentials and even some smaller details in Blender these days because it’s much faster and simpler to modify any part of the model without breaking other details. Then I go into a parametric modeller (Fusion360) to get every detail I need. Did your gantry hold up like you wanted?

@@machsuper hell yeah, and even more hours drawing them up to make sure they are going to work as intended. I use SketchUp predominantly for my drawings and reluctantly starting using components and groups to stop parts sticking together. I looked at learning Fusion 360 but knew they were eventually going to stiff people and start charging or remove functionality. Sometimes you hate being right. For the most part yes, but using two NEMA23's on the Y axis it can cause racking issues if I have problems with wiring or software glitches, a couple of years back I started on modifying it to be driven by a single NEMA 34. But from a rigidity stand point it was a good call, even thought it does complicate seeing things occasionally. My main goal was to get the spindle in the middle of the X axis gantry frame to make it as lever free as possible (was originally thinking 5 axis and supporting both sides). Bearing load was my primary concern of the design and I have 340mm between bearing end to bearing end, and the updated version of my end plates is 360mm. Like you I made an error in not allowing myself enough length in the bed frame to allow for a decent width gantry. I am very close to getting 1200mm (once finished) of Y travel but I am just a fraction shy. I used 75mm box for my main frame, and some 65 x 35 for the bed. I wish I had made everything out of larger sectioned box.

My latest one includes what you talked about like linear rails, square tunes for torsion stiffness etc. I would also recommend tooling plate aluminium for the bed as it can be used as a good reference for tramming. I went with premade 'z axis' for all axes, with the y axis turned on its side, so 2 rails on each side, 4 total and 8 bearing blocks to make it really rigid. I'm interested in adding more axes to the current 3 so I'm looking forward to how you progress your build!

Excellent illustrations for the different types of gantries and movements of the various axes. One downside from my experience selling gantry style machines is the ability to move heavy workpieces using forklifts onto the bed of the machines. If the machine has structure above the bed, a forklift will not be able to lower a heavy workpiece onto the bed, but that types of machine can be more easily design to be more rigid, so there are a few tradeoffs. A single ballscrew for the table style can cause racking, so depending on the width, you still may need two ballscrews at the extreme sides fo that table. I'm sure your mentioned this in a previous video, but what CAM program are you using? Fusion360? Your overall mechanical and strudtrual solutions for your machine is great and I can't wait to see your development. Keep up the great work.

Your frame will always have some flex. Even 500,000 machines show this to some extent. If you want to get that out completely, it won't be easy, especially if you want to machine materials like aluminum or metal. You have to find the right balance between the stability of the machine and the right programming. You can get a lot out of programming. Have you measured the clearance of the milling spindle? Your frame will eventually be stable enough then it will be the spindle that is next. But very cool project keep up the good work. You have more intusiasm than some mechanical engineers I know.

Certainly every machine has flex, just a matter of eliminating it enough to suit your needs, right? What do you mean when you say ‘spindle clearance’? Thanks for the comment, man.

@@machsuper Exactly. If you work mainly with wood, a little flex won't matter and you'll save a lot of money. You probably won't even be able to measure the deviations. If you want to work metal at full throttle, it will be really expensive. With spindle clearance I mean the concentricity of your spindle. When I move the spindle on a $1000 pillar drill at my local hardware store, it has a lot of play and the runout is bad. You can see that the drill is not running true. Your spindle doesn't look like it, but with cheap spindles there can be flex. It is not always the fault of the frame. Especially after a crash you should check this. In woodworking it is mostly unimportant in metal important if you want to keep tolerances. You can also compensate it with Milling Same or Counter Direction. The tool can also make a difference. Tools for metalworking will never run as well in wood as extra cutters for wood. These usually have a different angle and different coatings. In the beginning, carbide tools are perfectly adequate. If you want to use the machine to its full potential, it will not be enough. High performance wood cutters are therefore equipped with diamond. Unfortunately unaffordable for private customers.

It's interesting hearing those infos about a CNC gantry while in the 3d printing space people try to make them as light as possible to minimize inertia for higher speed without loss of accuracy, going as far as making them out of carbon fiber. Also we know that "moving bed" design as "bed-slinger", which is now considered more or less obsolete. Especially now as modern printers modify motor movements in real time to reduce vibrations ("input shaping"), and it turns out having the resonance frequency change as the printed object gets heavier on the bed is not ideal compared to moving a much lighter gantry.
@machsuper
@machsuper Жыл бұрын
All the immense effort that gets put into making these super heavy, stiff structures for CNC mills all comes down to the simple fact that the tool experiences forces while working. It's the key difference isn't it? It's the key difference between why a 3D printer should be carbon fibre and a mill cast iron, steel; granite or some heavy, stiff composite. I have wondered about building a machine out of carbon fibre though. If it's so strong, and light, could it make for a great high speed mill if you can work out the resonance? Interesting point about the changing resonance in the 3DP bed as the part gets heavier. You clearly have looked into the details of 3D printing more than me.

i wonder if it's possible to make a moving bed design, but effectively the opposite from the depicted model, where it's combined with the moving beam, so you handle the x and y with the beam, allowing the mounting on the components to be very rigid to facilitate rapid motion of the cutting head, but handle the z axis with the bed, raising and lowering the whole workpiece, that way the mass of the piece would have less of an effect on the mechanics of the system, and you could use a set of robust worm gears at the corners, a series of hydraulic pistons, or some other method that hasn't occurred to me at the moment, as the means of lifting the piece, whichever permits the highest degree of precision.

Unfortunately that’s not a good approach. Imagine machining the inside of a deep bowl shape about 300mm deep. The gantry will collide with the rim of the bowl unless you make the spindle permanently hang very low down from the gantry, in which case, you may as well just put the Z axis on the gantry. Also, putting four drive mechanisms on the bed is a lot of extra cost and a lot more opportunities for failure. It’s great that you’re thinking outside the box though, keep doing that. 😊

I do all my animations in Blender, I’m lazy and tend to do as much of the texturing as I can with procedural shaders as well. The trick to the animation around t=119 was Shape Keys. There was a base model (original design), then a shape key of the thicker, updated design. Then you can animate between the two. I definitely do want to make a lot more videos around creating and running 5 axis toolpaths. I’ll be getting into that in the future as it comes time. If you want to make videos, make sure to get your first video out. It will probably suck. Mine did, but you just power through it.

I think, if you’re doubling doubling the same size gantry that you were already using, then of course that will improve rigidity. But if you’re taking up that much space with two gantries, you may as well take up the same space with one very big gantry and stand it up right. The two small beams are losing out on a lot of potential horizontal stiffness by not being tied together for their entire length.

@@machsuper Hahaha oh when you said you built the other machine at 19 I was thinking it was only a few years ago. I'm similar in that I have spread a lot of interests rather thin, but I'm a few years older. You have obviously achieved some great depth though. Keep up the great work!

Thanks man! Sometimes the wide spread of interests and skills stresses me out because I can’t go all out on one thing. But KZbin combines many of my favourites, so I’m ready to put a lot into it. Plenty more to come!

when a new video I would like to build such a milling machine myself, you will share the plans. Greetings from Poland. I have a small milling machine, my daughter is sick and uses a wheelchair, you can always do a project on such a machine

It would be awesome to see a tutorial covering the animation side of the project. (Or if you saved any screen capture a timelapse maybe?) ☺

A few people have suggested that. It can't do what I need. It doesn't have RTCP as mentioned in the video.
