I am trying to make a bevel gear using a 60 deg. cone shaped end mill. I have a flat (1D) drawing which looks like a spoked wheel with each line representing the valley of a gear tooth. I have not done any work with 2D or 3D design so my challenge to is come up with the G-Code to make the valley for gear teeth.
If you can imagine a gear, the valley will be deepest at the OD and end at the ID. The Max depth of the valley will be .25" at the OD with a linear incline to 0" (top of material) at the ID. For testing purposes I will used some round aluminum stock which will be machined at 90 deg. Once I have mastered the setup the final gear configuration will have a pressure angle of 20 deg. so it may resemble an actual bevel gear.
I know what I am doing is not a real or legitimate method of producing a gear, my application will apply very little pressure so therefore it should be sufficient.
Are there special G codes for this sort of machining or do I need to move to a 2 or 3D CAD/CAM setup? If this easy code that someone could share with me it would be greatly appreciated. I am using MACH2 s/w with TAIG CNC mill.
Thanks
