    When I was offered the opportunity to beta test an upcoming robotic arm from Tormach, I knew exactly what I wanted to do with it. CNC chainsaws baybeeeeee. Aside from being fundamentally awesome, it is a very interesting software problem. Since I didn't have to build the arm I was able to focus the project and the video on the software challenges of making something like this work. Thank goodness I didn't have to build the arm because the software almost killed me. I can imagine all kinds of next steps for this creation like machining textures with the chainsaw or cutting topiaries. I hope you like it!

      There is a farming term that is applicable here. And I just realized I only remember half of it. Blood something. It refers to the area where if someone is in and you are swinging a harvesting tool they are going to be bleeding. Google has no idea what I am talking about because fortnit still exists, and some people think a scythe is a weapon.

      Could a larger motor on the base connected to the saw via a stout flexible drive cable be used to deliver enough torque to cut wood at normal speed?

      Yeah, that anti kickback tooth needs to be filed down as you sharpen the chainsaw blade. Usually go somethin like .3mm bellow the actual sawtooth for hardwood. Do try to make the dog out of a log, but you'll need to sharpen the chain a couple of times mid process though😅

    13. NobodyMinus

      In terms of pretty useless advice here, I think using alternating direction method of multipliers would achieve pretty much the result you were trying to get with gradient ascent but without being so likely to get caught on local maxima, though saddle points can still be an issue. It's usually used to find minima, but would work just as well here.

    14. AC Blaze

      You can file down the rakers. Edit: the "anti-kickback tooth" doesn't need to be up to the top of the flathead.

      As an engineer I have to say that I have been bamboozled . great vid

    16. jaxen coe

      why dont you just make the algorithm run a decent amount of times more for each cut you want to make to weed out the false summits. just log the results for each run and compare. tallest point wins.

      1. jaxen coe

        cut the log into a cube grid pattern in 3D and take one cube of the log at a time and make those guess on the surface of the wood

      Those little Milwaukee hatchet saws are one of the best tools I’ve ever purchased! I will probably buy a couple more. They are so light and just cut so well. Was very surprised by them

    19. Robert Hart

      Surely a regular 4 or 5 axis cnc router would be a better / easier less time consuming method of making a wooden bear from a log? I definitely understand the fun of a diy project but why this when you could use regular gcode from fusion360 with a CNC router and get better results?

    24. Michael Mayfarth

      Those little things you called anti-kick backs are actually called Rakers. they keep the tooth from taking off a bigger chunk than it should. you can file them down a little but that specific style bar was never meant to cut with that smaller section of rounded tip. look at the bars they make for chainsaw carvers and you will find much narrower tips that also have more flat area at the end. Hope this helps.

    25. Frank Murphy

      I've spent a good amount of time chainsawing, and I can say that that little chain on that little saw would get dull very quickly, especially if it's always going in tip first, even with softwood. I'd guess that's why it got so hot. A longer chain with a built in cutting oil squirter on the arm seems like it would be crucial. That being said, awesome video as usual. The sheer perseverance your projects take is nuts.

      Hey Stuff Made Here, just a quick FYI for you.... your background music is way to loud in the bass section. It's sounds 'normal' on my phone speaker, actually sounds quite good, but switching to my quality headphones causes the bass to boom as loud or louder than your voice, and through my big stereo it's damm near shaking stuff off the wall! :) You should produce dance music, you'd be good at it 😁 but on a serious note you could probably cut out or quieten a lot of the bass with no noticeable effect for most viewers, maybe even save some processing time 😉

    39. daneshannonsparks

      I'm a 3D tech artist and I'm intrigued by this problem. I feel like there's an elegant procedural solution for this. You mentioned that a convex hull wouldn't do the whole job, but that doesn't make it worthless. You can compare the polygons of the convex hull to the polygons of the original model. Any polygons that they have in common will define shearing planes that will need to be cut out of your starting block at some point anyway. Any polygons that they do NOT have in common define the inner surfaces of the cuts you would need to make to define the concavities, and I feel like it's an easier step from there to finding a procedural way to remove them without testing random cuts. I might try to write a Houdini tool that figures this out, but it definitely seems doable.

      17:29 also, you should adjust your chainsaw, so it is tighter, and probably put some oil in that bin....

      What software do you use? we use fusion 360 for CAD/CAM

    43. foogermier

      Those "anti-kickback teeth" are called rakers. They control how much wood gets chiseled with each tooth. If you were to file them down using a depth gauge tool and a square file, and made sure you had lots of bar oil, you should be able to cut for a while.

    44. The Monster Under Your Bed

      Smart enough to make a robotic chainsaw artist. Not smart enough to realize that a polesaw, only designed to trim 2-3" tree limbs, isn't adequate for cutting through an entire log. Also not smart enough to realize that when you bend a chainsaw bar, you need straighten it/replace it or else you won't get straight cuts.

    45. Kieran Asman

      What tablets are you using to sketch on, and whats the software? I have been looking for a nice tablet to sketch and workout stuff on

      I have an idea i want to patent tht is an easy solution to one of your more advanced robots. Thought about it before i even seen your video. Easy simple idea tht should sell worldwide and easy and cheap to produce. Would love you to produce it, if u could we can split the profits???

      I mean I’m not a coder by any means so the possibility or difficulty of coding to do so, I don’t know, but having it use the tip of the chain saw side to side to “grind” the smaller/tighter areas to get those curves in could work?

      This is the epitome of not actually doing anything new or with substance, but the viewership! You used an already existing arm, with already existing software on top of an already existing polesaw. This is the origin of originality! YOU WROTE SOME CODE and put a saw on an already existing component, the genius. Dipshits enjoy your work. Anyone that cares, despises you. "please consider subscribing, it really helps me out". PANDER PANDER PANDER, I'm an Engineeer!

    57. DrJibson

      So you're a guy that uses a CAD program then has machines make what he designed in CAD. By "he designed in CAD" I mean you used software to create the whole thing, then a robot to make the whole thing. The absolute definition of hands-on-engineering. You deserve millions of dollars. Also, this type of pandering is the most pathetic version anyone could come across. The pocket engineer for views! That was the point of engineering, youtube views, you're doing it right. Makin' that money while saying fuck that shit to actual engineers fighting the barriers that hold us back. You're the man! You know how to string up a noose? People with intellect actively raping the shit out of their piers they refer to as consumers. MY MAN!

      A fairly simple solution to your false peak problem with gradient ascent is to put in multiple "balls" in different places - run the algorithm multiple times with different initial positions - and compare your results to find the actual peak. 3 blue 1 brown's Machine Learning series has a video on this, episode 2. Gradient Descent around 6 minutes in describes the algorithm.

      “That’s why I have this bar. When you have a bolt that’s really stuck, you push way out here aaaaaaaand.... Snapp your wrench in half.”

    75. Auburn Elvis

      Did you consider re-making the chainsaw? They make carving discs that are basically chainsaw blades fixed to a disc. It seems like starting from there could solve your gouging problem you had with the tree saw.

    76. Hubert Lenningrad

      Not gonna lie, this one was a little boring. You took a premade robotic arm and mounted a chainsaw. I prefer some of your other content (full marks!)

    77. Cloud Wolf

      Gradient ascent/descent has many well known ways to prevent getting stuck from increasing the rate of convergence to using momentum

      1. Cloud Wolf

        @CouchPotator im sure ppl have tried that but the most common methods is increasing the rate of convergence to hopefully "jump" past local max's, or momentum which essentially if a maximum isnt maximal enough u will probably "slide" past it (which is as simple as just taking a LPF (just 2 or 3 + / * operations)

      2. CouchPotator

        Couldn't you form a grid of points and run the algo on each point and choose the best result? Easy optimize, if you hit a spot already looked at, stop that point. Only problem would be the resolution of the grid, but that would be determined by the resolution of the model, which in this case is very low.

    78. Peter Gersbach

      Did you double check the chainsaw blade wasn’t running backwards?

    79. ViconDeutz YT

      If you ever try to do this again use a softwood it will cut a lot easier and you can use the tip of the saw.

    80. Aku Saikkonen

      I love your content and all the great ideas you end up making. It's cool to see both the process and the result. Your content is very educating and fan to watch. Also I like your music taste and would love it if you could link the songs you use on your videos in description. You do great job and the effort you put in to this is on another level.

    84. Sage Edwards

      To your gradient ascent question, they have a method called stochastic gradient ascent that helps get you out of these problems of "false peaks", and finds the global maximum rather than the local.

    98. MPGamingCentral

      What you called an "anti-kickback tooth" is actually called a raker, it is there to control the depth of cut for each tooth. Considering you are using a robot to do the cutting, I would assume you could have the the arm control how fast you are cutting quite accurately so they are kinda pointless in your case. if you ever come back to revisit this I would suggest filing the rakers down to help with plunge cutting. All that being said, I'm not too sure why that would be causing a problem. Possibly since it is a pole saw meant for branches, it may have a smaller diameter tip on the bar that might be causing it. However, I am not sure. I do know that plunge cuts are definitely possible with a full size chainsaw though.
