I know that there are several opensource printers, i.e. RepRap. Are there any similar projects for robotic woodworking saw or other instruments?

  • What kind of saw? There are plenty of homemade table saws and band saws on YouTube, though I don't know how many of them qualify as open source. To me, the word "free" is more applicable to the design of a non-software item, such as a woodworking tool, since there is no source code hidden anywhere and the design is based off plans. – grfrazee Oct 21 '15 at 16:51

    This reads like a request for plans or at minimum asking for an external resource which is off topic. Nothing is stopping your from asking in chat though. – Matt Oct 21 '15 at 17:20
  • @grfrazee I rather new to wood working, but I'm guessing what I really want right now is a band saw or keyhole saw, where I could cut a panel into or shape or maybe ever cut portions out of the panel. – Antarr Byrd Oct 21 '15 at 17:24

    I suspect what you're looking for are CNC routers rather than saws. They're often used to cut complex shapes into or through sheets of material. – Jonah Oct 21 '15 at 18:05
  • I think I need bot @Jonah, but really the bandsaw as I would like to cut some sheet in the shape for a dog house and other projects. But thanks, I've never heard of a CNC router. – Antarr Byrd Oct 21 '15 at 18:57

I don't believe there are many common computer controlled saws except for custom-built, highly specific machines.

However, there are three common machines that are more general purpose that can probably do the job you need:

  • Computer controlled routers
  • Computer controlled laser cutters
  • Computer controlled high-pressure waterjet cutters.

There are many open source and custom built, as well as commercial CNC routers. As for the other two, I think those remain mostly commercially built.

There are also many companies that operate these machines that will cut things for you, for a fee.

  • Note that there are CNC router kits as large as (and functioning like) panel saws, which would make them a fairly reasonable equivalent for your "bandsaw" needs if the stock is fairly flt (or can be built up feom flat pieces).A friend was considering investing in one of those; I'm not sure whether he ever gotnenough interested parties together to justify it. – keshlam Oct 22 '15 at 1:39
  • I'll also note that a low-budget homebrew was published about six months ago which is router with a side-cutting bit, hanging against an almost-vertical plywood workpiece from two strings which can be wound/unwound via stepper motors to move it across the surface of that sheet. It doesn't have any z-axis control so you have to manually start and stop each cut, and its accuracy is relatively low, but if your goal is mass-producing plywood cutouts that don't have to be too exact it's the cheapest solution I've yet seen. – keshlam Jan 12 '17 at 22:09
