This section covers how to actually make parts. Knowing what material to use means nothing if you can't turn it into the shape you need.
Subpages cover manual machining, CNC/laser cutting, sheet metal, 3D printing for FRC, and tolerancing. Even if you mostly use COTS parts, you'll need to cut, drill, and modify things constantly. The more comfortable your team is with fabrication, the faster build season goes.
