锻模设计与制造之间的传统信息媒介为工程图纸和工艺文件。工程图通过视图、剖面表示三维形状,由尺寸标注给定大小。制造者按照约定规则理解执行。显然,其信息完备程度低,不能为加工设备直接接受。因此,需人脑通过想像补充细节,再经自动编程计算机产生NC程序。这就是最初的计算机辅助制造(CAM),如APT、EXAPT等系统,至今已有三十年历史。而后兴起的计算机辅助设计(CAD)通过几何造型系统
Forging die design and manufacture of traditional information media between engineering drawings and process files. Drawing through the view, the cross-section that three-dimensional shape, the size given by the size. The manufacturer complies with the rules of understanding. Obviously, its information is incomplete and can not be directly accepted by processing equipment. Therefore, the human brain needs to supplement the details through the imagination, and then automatically programmed computer generated NC program. This is the first computer-aided manufacturing (CAM), such as APT, EXAPT and other systems, has 30 years of history. The rise of computer-aided design (CAD) through the geometric modeling system
