Utilizing Computer Aided Design (CAD)
The process of photochemical metal etching begins with the creation of a design using CAD or Adobe Illustrator. Although the design is the first step in the process, it is not the end of computer calculations. Once the rendering is finished, the thickness of the metal is determined as well as the number of pieces that will fit on a sheet, a necessary factor for lowering the cost of production. A second aspect of the thickness of the sheet is a determination of part tolerances, which hinge on the part dimensions.
