If you are in Metalworking, Metalcutting, Automotive, Medicine, Machinery, Aircratf, Aerospace, Jewelry, ..etc. sectors, You must use CAD/CAM/CAE Software programmes to design and manufacture by using CNC Machine Tools. By using this e-book, you will be able to have some information about CAD/CAM/CAE Software compaines in the World. In my opinion, If a country wants to thrive, it must invest on CAD/CAM/CAE Software Technology. It is very important . If a country wants to thrive, it also must invest on CNC Machine Tools Technology to manufacture any kind of parts in every sectors and it must invest on Cutting Tools Technology. There are three trivets to be a developed country, You should have a CAD/CAM/CAM Software Technology infrastructure, You should have a CNC Machine Tools Technology infrastructure, You should have a Cutting Tools Technology infrastructure.
