Patent that toolpath boys, oops, too late.
As many of you will recall, I set up www.open-source-cnc.com about a
week ago. Small beginnings, but Rome wasn't built in a day. So, to the point. Why is open source so good and closed source so evil? Well, to give just one example, Delcam have been awarded a patent on tool paths, yes folks, if you generate a more efficient toolpath for your work than say "30% cutter overlap all the way" then welcome to the world of having your ass sued off by companies who aren't interested in anything but THEIR profit. What's next? Patenting the more useful roughing and finishing techniques? Patenting variable spindle speeds through a toolpath? Patenting collision detection and gouging alerts? |
