CNC Lathe Program for Fresnel Lens

This project is to help create a Fresnel lens for a solar powered cook top to be sent to third world countries to reduce the safety and health risks of families. I need an aluminum mold machined by a CNC lathe to make a Fresnel lens out of either PET or PMMA (both thermoplastics). What I'm looking for is a computer program that can be read by a CNC lathe to make the mold required. the thickness of the material will be 2 mm and the diameter needs to be variable (as I'm not sure what size is required but we will start with a test piece of 100 - 200 mm in diameter). Here's the patent file for Fresnel lenses: [login to view URL] which should specify the basics for creating one. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No 3rd party components unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the worker's Worker Legal Agreement). ## Platform CNC Lathe (Not sure there's a specific platform for that)
