Keep going with freeCAD.

So good don't stop

question; Is how to create gears in freecad Path Workbench for cnc, I can create and 3D print gears to make sure I have the have right gear reduction and torque. I want to then cnc cut the gears out of foam for casting into aluminum using lost foam casting technique. Problem is to create Gcode files in Path workbench. Any ideas would be appreciated.

Thank you for showing me tipps and tricks in FreeCAD. But combined gear wheels should have the same module, and that's not easy, when you use three different modules (0,633; 0,75; 0,8) for three gears ;-)

Yes, thank you for that clarification. The only modules that combine between the new gears are the .75 and the .8, which are close enough to mesh just fine. I should have used the module as the primary driving input, rather than the outer diameter of the gears, though.

@@KTECDesigns the module should be the primary driving input. And yes, meshing gears must have the same module, anything else, even close ones, will result in excessive wear and therefore, dust and garbage around. Also in some cases they can simply jam. The same goes for the angle of an action. Since you were designing *both* meshing gears, you should have been able to measure the distance between rotation centers and, knowing the number of teeth on both of them, you might directly caclulate the precise module.

Hello . How did you calculate the value of 0.633? It was a useful video

Nice video thank you, but, how did you slice it? Also, what was that noise in the background, it’s a bit distracting. Cheers

Hi, thank you. Do you know how to make a part of gear? For exemple cut it in half?

Well, make a gear and then use "subtractive cube" or "subtractive cylinder" in Part Design. With the proper adjustment of the cube you can easily get 3/4, 1/2, 1/4 of a gear, and with the cylinder you directly specify the angle of the sector you are cutting away, so that can result in any sector of a gear. You may also use Part Design's boolean operation, that is very generic; you need to create another body, either a "cut-out" or "leave in", and use a boolean subtraction or boolean common between the gear and the supplementary body. Also, you can switch to Part workbench and use it's boolean operations between gear and any other body, which might be easier.

Nice video but I think your title is messed up. Looking forward to mor, though.

Yikes! Thanks for pointing that out!

need to show how to convert to stl files, otherwise it was a good video

I watched your video for 22 seconds! You must be smarter than ANY college professors I have ever learned under!!! NOT ONE of those professors played music in the background, WHY? Maybe they did not want any of us to get distracted!!!!!!!!!!!!!! Are you smarter than ANY college professors or do you just like to DISTRACT us?? If you take the music out of the background and re-post it I might watch.
