To use this model simply edit the equation values to match your tool setup. This is intended to be used with router bushing guides and the lip that it prints should be trimmed using the router itself before using it on your project. This ensures that the dimension will be exactly what your router is going to cut. Then you simply line up the trimmed lip with your radiused section and cut away.
There's a puck for cutting external radii and a ring for internal radii.
