Once the manufacturability analysis is full, there will be a ultimate store drawing with in-depth calculations of stress/strain ranges and cargo limitations. The info out there therein will decide the sheet metal fabrication course of. Every speedy prototyping course of begins with an idea, and sheet metal design isn't any exception. You can put these ideas down roughly to offer practical requirements on your project. It may also contain the designing of a 3D model of the desired sheet metal part. The model usually includes Air Conditioner Fan requirements for wall thickness, bend radii, hole orientation, bend allowance, and more.
