Attached are three files:
The DXF file was drawn in AutoCad Lt (2008) could have used a newer version, but it is the one I use most often.
The LCAM file was created from the DXF. LCAM is not my processor of choice, but since that is what you are using I went that way.
The txt file was created by LCAM. I added notes to the original tap file and re-saved it as a txt file. If the dimensions look to be to big it is because the outer edges of the ellipse are offset to account for the diameter of the cutting tool. I used a pocket for the inner circle rather than just cutting the diameter of the circle. Not sure but maybe I should have made the depth deeper (used .146 as the depth).
Note that the crowned torus was created using a .25 diameter ball end mill. Doubt you could find a .22 mill. The larger diameter will impact the edged of the center cut out slightly.
In order to create the flat torus you will need to make a separate tap file using a .25 flat end mill. That male flat torus would have to be attached to the the completed male product.
I don't do any type of mold work so I am not sure what I have created will even be of use to you. Nonetheless, it was an interesting project to play with.
Good luck. Let me know how your project turns out.
