Making (Materials option)
Muhtasari
Once a product has been designed on a computer, the same digital information can drive the machines that cut, shape and build it. Computer-aided manufacture (CAM) is the use of computer-controlled machinery, laser cutters, CNC routers and mills, 3D printers and robot arms, to make products directly from a digital design. The model the designer drew becomes the instructions the machine follows, so what is designed is exactly what is made.
This note examines making with CAM in the resistant-materials context. It sets out the advantages of CAM, such as speed, accuracy, repeatability and the direct link from CAD, and weighs them against the disadvantages, including high cost, the loss of some manual skills and the consequences of a machine repeating a mistake perfectly. The aim is to let you argue clearly about when CAM is the right way to make a product and when it is not.
