I need to design some custom involute gears for a project that I am working on and this is my first dive into gears.
I worked out how to calculate the size of gears by the required numbers of teeth and module.
This gear dimensions: Module = 1mm Teeth = 36 Clearance = 0.1 Pitch Diameter = 72mm Outside Diameter = 74mm Whole Depth = 2.1mm
As you can see it's a tiny gear and I'd like to be able to make the blade to cut this gear myself.
With a standard pressure angle of 20 degrees, how would I calculate the angle of the cutting surface to make this gear profile?
