Making (Materials option)
Bayani Gaba-gaba
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.

- What does CAM stand for? A. Computer-Aided Modelling B. Computer-Aided Manufacture C. Computer-Assisted Measurement D. Computer-Analysed Materials Answer: B
- Which is an advantage of using CAM to make products? A. It is always cheaper than hand making for a single one-off B. It produces identical, accurate parts repeatedly and quickly from a CAD design C. It never requires any trained staff D. It cannot make complex shapes Answer: B
- Why can a fault in a CAM program be especially costly? A. The machine slows down to avoid the fault B. The machine repeats the same fault perfectly on every part, wasting a whole batch C. CAM machines cannot make mistakes D. The fault only affects the first part made Answer: B
