CAM: Computer-aided manufacture
CAD/CAM allows for rapid prototyping more than anything else.
It quickly transforms virtual objects into real objects. And because the object starts off virtual, as a software, it can be altered easily and repeated consistently. It is an iterative process.
The software used (which costs an amazing £700!) is compatible on PCs only called TechSoft 2D Design. It draws in vector format like Adobe Illustrator. There are grids and guides like Creative Suite too, called the Lock feature, of which there is step lock and grid lock, with each parameter able to be determined for each document. It's rather straightforward and easy to create shapes.
The printing process involves a couple of settings to be decided. It all depends on printer type, material type, cut or engrave. Laser cutters cut vector files or engraves bitmaps. The properties are a balance between power and speed, ie the strength of the laser and how fast it moves along the material, therefore determining how deep the cut/engrave is. There are given guide figures for different materials of different thickness.
