5short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is cAD?Show answer
CAD speeds up product development because ideas can be changed and re-tested on screen instead of rebuilding physical models, and the same file can be shared instantly with clients and factories and used to generate manufacturing data.
What is cAM?Show answer
CAM gives high accuracy, repeatability and the ability to run unattended, and it links design directly to production so there is less chance of human error in transferring dimensions.
