Because CAD/CAM allows designers to focus more on actual design problem and less on time-consuming, nonproductive tasks, product quality improves with CAD/CAM. CAD/CAM allows designers to examine a wider range deign alternatives (e.g., product features
9、) and to analyze each alternative more thoroughly before selecting one. In addition, because labor-intensive tasks are performed by the computer, fewer design errors occur. These all lead to better quality. (3) Better Communication Design documents such as drawings, part lists, bills of material, an
