Please consider supporting these projects through my patreon:
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!

    We have a fanuc robot at work... its interfaced on a simple interface... ie... known grid... and a pallet change... I must say... using the robot to push the shuffle around a common axis is innovative to reduce the cost of a seperate drive motor... How you go about asinine ways to explore potential... gives me a chuckle... im not versed in robotics... but you sir have a potential... your intuitive nature will lead you to advancing machine procedures given time... or maybe someone will help Jumpstart your mind where to look... as in waste generated from tool tip... You are one step away form genius... ;) tackle the issue on time... its comparitive... money in... money out. Have a few ideas been floating around for some time. .. 1st rule... let gravity do its job...simple designs can become redundant. From a procedural point of view. Its realizing where to invest the time... What is your motivation? Ya C axis (rotational) with one fixed axis... scale that up... think the bay of fundy... canada.... 60 foot tide... do a coffer dam... re-enforce it... build a lock around it... build concrete floats within that... span the gap inward by a bridge crane... make it tuff as nails... say tower at center to support 1/2 the overhang... So lets say I want a 1000 meter diameter... seems within easy possibility... K bullet points... whats the discharge rate... said locks can disapate water... ideal would be 1 tidal cycle... if we only use a fraction in one stroke... how do we store wasted potential.... basically it boils down to kinetic.... say we want to engineer past limits on drop forge tech as is... go all in... look at it as a all in one... all or none... if you look at a swimming pool... could you not put a upwards force on a float... pin it to a wear plate.... for the linear axis.... drop water level... and said points of final reference... big is not the question... its when we go that way. Why not go deep... we look for fast motions... when we know... torque... rigidity works... so why not go down 5000 meters into the sea... Why not go to the very bottom.... form a pressure vessel at surface... cut into it a conical plug thru... the geometry will self seal by pressure difference alone once applied. So many questions... If its a question of safety... than tackle that... outside of laser and visual... how do you eliminate contact... so its audio?

    Hey, you should try an offset grinder with the chainsaw blade. You could probably do more intricate cuts. Just a thought. I could NEVER figure out how to do all that you did.

    Things you need to change for next time. Wood choice: Cedar! Its the only wood sculptors use because its the softest and easiest to cut. Also, you have to have OIL on your saw or else it will overheat every time. Love watching your vids.

    there is a very easy way to generate gcode for your 3D pattern. approach the problem similar to wood turning. you take the 3D model, pick an angle and project it into a 2D plane (kinda like holding something to sun light and drawing around the shadow). now your problem is to find triangles inside of a an image, there is a greedy algorithm for squares where you set a resolution size and break everything into squares of that size. then you bundle every 4 adjacent square into a larger square. the complexity of your problem also scales linearly with the number of turns you want. This is very scalable as well. this is how GPUs draw fragments.

    Re making wood scupture... You're just going to have to learn how chainsaws cut. It's pretty simple physics, so you should catch on quick. There's a whole lot of guys out here on USloft with nothing but chainsaw content. One of the biggest factors is probably going to be sharp chains and properly gauged rakers.

    Machinists know there is an optimum chip load, speed and feed for cutting different types of materials, depending upon the cutting tool geometry and strength. I am only halfway through the video - hoping that comes to mind.

    @11:00 I can think of 2 options for the cutting problem. Option (1) is a combination of the 2 original cutting methods; do a best cut line and then do a refining pass like your apple peeler. Option (2) would be to collide a planar perpendicular to the angle you wish to cut; it would something similar to the calculation for magnetic flux to antenna.

    Hey, I have a chainsaw. They really don’t cut well after just a few hours of use. They need to be sharpened regularly. Take it to your local hardware store. Better yet, by several and have them in rotation - always one sharp. If you are seeing powder or saw dust it’s too dull. If you see miniature ticker tape it’s good and sharp. Thx for the inspiration.

    Great video. If you run your ideas past an old lady "The Old Lady Test" approximately 80% of your time can be saved going down non-working paths. You simply state the idea, then, any lady that has made it to 75 years old will immediately tell you what's wrong with that idea. For example, as soon as you showed up with that cedar tree she would have said, "Did you dry it out first?", or "Will that chainsaw I have seen only cut branches actually cut a log?" Also, "Do you really need to write code to know the precise shape when that saw will not cut exactly" or "Why are you using a chainsaw to wittle instead of a chisel and hammer?" or "Why don't you start small and work your way up" Lastly, she would certainly say, "Use pine, it is a soft wood"

    I wanted to add another comment because I had this on the backburner for a little bit and a solution popped in my mind, as a programmer - how would I accomplish this... I don't know much about modeling, and I wish I did, but converting motion capture to g-code wouldn't be super difficult... You could capture the motion of one or more of these chainsaw artists and replicate what they've done. The arm could handle it. The rotational element would be opposite of their movement around the item. And you could get incredibly accurate reproductions by doing this - although they may not like you selling a replica of their making via a robot though, but I'm sure there are a few people willing to try this.

    Hey, about making the gradient descent work - a nice way I know of is using stochastic gradient descent which is much more likely to converge to absolute min/max since it makes random jumps driving away from local minima/maxima.

    You can also wire yourself up so that if you touch the saw you close a circuit which kills the saw. This is used in bench saws. Maybe it can be done capacitatively, so if you come to close to the saw its capacitance will increase and this can trigger it to stop

    Here's an idea. The divine combo of carbon and silicon. Use your setup to manually chip away at the log, restricting your movements with your software model. Ok, maybe clunky unless the robot isn't really flexible. How about this: use a laser to "color" the log where it needs chipping until a dog is all that remains. (Is that a thing? I feel it should be. There is no way no one has thought of it.)

    @Stuff made here, just an idea for using the estop when your in the kill zone. We use a double deadman switch for programing our material handlers. Ours are built into our tech pendants but it wouldn't be hard to make a stand alone one. Basically it's a switch that you hold half way down in order for the robot to move. If something happens and you release the switch it kills the arm and if something scares you and you tense up and push the button further down it'll also kill the arm. It's a pretty safe system. We also use cameras and stuff so that when you are in the work cell or kill zone the robot will only run at half speed. Then once you are outside the kill zone you don't need to hold down the deadman to the halfway position anymore and it returns to full speed.

    Dude, thank you for explaining this to me in a way that I actually understand. I was talking to a friend of mine recently (I'm 28) and we were agreeing that we, pretty much, learned not much of actual worth, in all our years of high school (in the UK). Teaching in the UK is no where near as good as what it should be, and I think it comes down to the teachers themselves. Not one that I can remember, looked interested in the subject they were teaching... From your videos, and your explanations, I learn more than I did while at school. Through you, and others like you in other subjects, I'm filling the holes in my education. Cheers. Love from Scotland.
