CAD/CAM is the advanced technology used in manufacturing process by the assistance of computers and softwares. In traditional manufacturing drawing is done by drafting in which modification and prototyping took more time and cost, but the latest CAD software’s eliminated this by software interface like ProE. Not only designing but also manufacturing was hectic involving lot of machine for single operations but latest advanced CNC machines integrated with computer known as CAM avoids these troubles.

Excerpt from the Book
Integrated CAD/CAM Systems:
The latest advancement in the CAD/CAM systems is the integrated CAD/CAM systems. This integrated system has been classified into two types as CAD-centric and CAM-centric according to where it is used. In CAD-centric the CAD system interface is the mainly used one but it also has the CAM features to support. For ex, solid works which is CAD software have this CAM integration in its interface provided by Delcam. Likewise the CAM-centric is the one mainly interfaced for NC programming but it has integration with CAD to make it easier to modify the 3D model within them. For ex, Cimatron provides built in CAD interface to make geometrical corrections. Thus these integrations provide lots of advantages but full features of both CAD and CAM hasn’t been brought together (Yares, 2012)
But Min Hou in his article about the integration mentions that because of this integration a better communication has been formed between both the systems which made production easier. He says that without the integration the part produced in CAD should be recreated in the CAM for generating the tool path and programs which is eliminated by the integration. It reduced the design cost also opened platform for new researches. The integration helps to import 3D model created by the CAD into the CAM as wireframe or even surface so that tool paths can be generated for them to manufacture by CNC (Hou, 2012)
