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!

      On the gradient ascent problem, this issue actually has a partial solution. Special optimizers like Adam and other momentum-based optimizers can be used to help curtail this issue. See here for some optimizers:

    because your cutting speed is controlled by the CNC you could probably just file off the depth guages on the chainsaw blade

    you need different chansaw blades depending on if you are going down the length of the log (ripping blade) or across the log (crosscut blade). if you try to rip with a crosscut blade you won't make any progress and you will just sit there and make your chainsaw overheat like you did. also buy a husqvarna

    That thing you called an "anti kickback" tooth is actually a chip clearing tooth for the sawdust. Around 17:10, it got hot because the teeth on the chain are dull. Cutting dry/cured wood is pretty rough on a chainsaw. It doesn't appear you have any method of supplying oil to the chain which is going to be detrimental to the chain while cutting wood as it needs the lubrication and cooling provided by the oil.

    Your current software / hardware setup got you to a rough shape, with most of the excess material removed. Phase 2 should be with a different tool (perhaps a drill bit?) and software that will plunge the bit into the material. Perhaps more than one pass with different diameter bits to get the "resolution" better?

    For the gradient ascent problem: Do like MC simulations? Change each parameter one by one, move them each a random neighboring number if it ascent accept, if it descent accept with a probability, the probability will encode how easiily you'll be stuck at a false maximum at the cost of more computational time.

    He should just use the Chinese method of problem solving. Step one: Find a company or person who already found a solution to this problem. Step two: Hack said company or person and steal their solution. Step three: Use the stolen solution and pass it off as your own. Step four: Deny that you stole any solution or that you're killing off an ethnic minority living in your country. This is similar to the Russian method of problem solving. Except you poison all of your political rivals instead of killing off ethnic minorities. Secretly you're doing that too but no one yet

    As a 5 axis CNC machinist this makes my head hurt. The chainsaw has what they call safety chain. If you grind away the safety kickers , but not the actual depth gauge/rakers you can plunge cut with it just fine. You can also twist the saw in the cut like a screwdriver to make a bowl shape as long as you are taking a very very shallow cut.

    Now being cnc programer once upon a time i know there is software for your robot arm. You need only to describe a tool (chainsaw) and graphicly describe in software what to do. P. S. Cut only with a tip - less Teath in wood less resistance.

    The tooth on the chainsaw chain you referred to is not 'an anti-kick-back' tooth, it is the guide tooth. It sets the depth the cutting tooth bites into the wood. Chainsaw cutting teeth are more like lots of little wood planes taking shavings, alternating side to side. The guide teeth are like the base of wood plane, and are set at certain cutting depths for different woods, hard or soft wood. Also, as the cutting teeth wear or are sharpened down, the guide teeth have to be filed to keep the cutting depth correct. You are lucky you did not get into a position where the teeth on the chainsaw tip dug-in due to the guide teeth not setting the cutting depth. (Check out some of the videos on here of chainsaw wheels on grinders). The extreme turn of a chainsaw bar tip renders the guide tooth useless for the brief time the chain goes around the tip. That's what kick back is, the teeth digging into the wood more like a chisel than a wood plane. Once the tooth has dug into the wood so far, the chain motion then sends the chainsaw in the opposite direction. If this had happened while you were cutting the wooden block, you may have damaged your robot arm.

    One of the ways that you can avoid reaching false summits is using a lagrangian with any closed curve domain. Then you can compute all of the maxima and find the global maximum in the closed domain.

    What a great idea. I think the best way to make the path file, would be to create a virtual log, and a virtual chainsaw, and then carve it out first virtually, saving each "good" cut to the path file. This could be done even better by having an actual wood carver help you create this file. Doing it this way, you would be able to better mimic actual wood carvers who first carve large pieces off the initial log before going to carving details, it looked like you were going for the details too early. This is a wicked cool project and I would love to see more work done on it.
