This is a common occurrence when manufacturers receive a sheet metal layout dimensioned in the flat pattern.
The goal of this manual is to help you gain an understanding of precision sheet metal layout and show you how to do flat pattern development while becoming more efficient with math in the shop.
3d cad files are converted into machine code which controls a machine to precisely cut and form the sheets into the final part.
In many naval construction force ncf projects sheet metal is used to protect the exterior of buildings by using flashing gutters and at times complete sheet metal roofing systems.
If you have been working in a sheet metal shop plan to work in one or just want to sharpen and improve your skills with sheet metal then this manual will help you to do that.
