GCSE D&T Resistant Materials: Tools and Processes - CAD/CAM - Advantages and disadvantages table in GCSE Design & Technology: Resistant Materials


	GCSE D&T Resistant Materials: Tools and Processes - CAD/CAM
	Advantages Save money in the long run Easy to develop and edit from all angles - easy to experiment with materials and finishes Can produce very realistic designs quickly on screen - helps boss/client understand the proposition Products can be machined at high speed and run 24 hours a day = lots in a short space of time Machines can work in human hazardous conditions i.e. paint spraying High quality and more reliable finish (no human error involved) Labour cost are lower	Disadvantages Very expensive to buy and set up Computers can be affected by software problems, viruses and corrupted files - potentially slowing down production Fewer workers = unemployment increase and traditional skills could be lost Traditional one off edge of product lost
	Evaluation Overall using CAD/CAM is very beneficial and as with everything there are going to be disadvantages, but I feel the advantages out-weigh these.

Save money in the long run
Easy to develop and edit from all angles - easy to experiment with materials and finishes
Can produce very realistic designs quickly on screen - helps boss/client understand the proposition
Products can be machined at high speed and run 24 hours a day = lots in a short space of time
Machines can work in human hazardous conditions i.e. paint spraying
High quality and more reliable finish (no human error involved)
Labour cost are lower

Very expensive to buy and set up
Computers can be affected by software problems, viruses and corrupted files - potentially slowing down production
Fewer workers = unemployment increase and traditional skills could be lost
Traditional one off edge of product lost

Overall using CAD/CAM is very beneficial and as with everything there are going to be disadvantages, but I feel the advantages out-weigh these.
