It is critical to take advantage of modern computing technologies to improve the effectiveness of engineering designs. The limitations of human designers can be addressed by computer programs. As shown in Figure 1.10, human designers and computer aided tools are good at providing a new design and a routine design, respectively. Statistics shows that the percentages for providing a new design, increment design, and parametric design are 24%, 56%, and 20%, respectively. The total new design only took 24%. If the requirements of standardization are high, the parametric design is higher, where 50% of design activities are of a routine parametric design.

While the majority of engineering design activities are incremental designs, the computer assisted interactive design can maximize the synergized strengths of both human designers and computer aided tools. This implies that engineers might spend a lot of time to repeat existing work by others. Therefore, it becomes mandatory to utilize CAD/CAM to improve productivity. CAD/CAM is designed to synergize the methodologies, tools, and expertise to solve design problems of CAD/CAM applications.
