SUMMARY
This discussion focuses on configuring inputs for machining an 18" diameter, 1.5" high aluminum disc to serve as a primary objective mirror for a telescope. The focal length specified is 79.2 inches with a ratio of f/4.4. The user is utilizing a CNC lathe and requires precise inputs for an AutoCAD program to ensure accurate cutting, specifically needing to calculate points along the 'x' axis to the perimeter from the center and the corresponding depth 'y'. The material removal required is 32.53 cubic inches.
