Cutting an involute gear out of plywood using a homemade CNC router
My homemade CNC router cutting an involute gear out of 6 mm plywood. I have to take just 0.5mm per pass in order to prevent burning when running at this speed. The router motor is a cheap Dremel clone and can't really give much power at low RPM. The gear was drawn in Solid Edge and the toolpath was generated using CamBam. Using custom software, the GCODE is transformed to individual line segments, which are then sent over a serial line to an ATMEGA168 microcontroller, which controls the axes under closed-loop control.
