DIY CNC - Making Gears With Free Software

Introduction: DIY CNC - Making Gears With Free Software

This was just a quick project to show how to use free software to make gears on a home built CNC. The video shows the process.

(1) A gear is designed in Inkscape

(2) The design is saved as an SVG file in Inkscape

(3) Go to www.MakerCam.com

(4) Ope the saved SVG file

(5) Convert the image to g-code after setting parameters

(6) Open the g-code in Mach3 and have the CNC cut the shape.

It's a fun project to tinker with.

    Seems to be some talk of "involute gears".

    This addon for Blender EXPLICITLY creates "involute gears" (just
    tested on the latest version of Blender as of this writing: 2.76b.
    Working. It's NOT the default addon.

    I'm always seeing what can be done with open source and free software and the gear function in Inkscape is just a cool little feature. I have Matthias' gear program it rocks - I've made a lot of different types of gears with it from planetary arrangements to rack and pinion designs.

    That's no involute gear! Anyone can make something that looks like a gear, but real gears use involute gear teeth. http://en.wikipedia.org/wiki/Involute_gear

    Agreed, plus it's far more work than just using free programs that are made for making gears, I.E. Matthias Wandel's gear generator program
