机械CAD图样处理系统智能化

运用智能工程的原理、技术和方法，为提高机械ＣＡＤ图样处理系统的智能决策水平作了初步尝试。根据知识表示原理和控制策略，将系统应用领域的知识集成，单独建立知识库，采用元控制命令协调下的并行结构进行统筹管理。研制了由零件图自动拼画装配图的智能化覆盖消隐技术、图形交互参数化方法及各种处理功能，提高了系统自动化处理能力。

THE STUDY OF RAISING INTELLECTUAL FACULTIES FOR THE DRAWING PROCESSING SYSTEM OF MECHANICAL CAD

Preliminary attempts have been made to raise the level of intellectual decision of the drawing processing system of mechanical CAD by using the principle, technique and method of intellectual engineering. Based on principles of knowledge representation and controlling tactics, knowledge of the system application field is collected, a knowledge library is built separately, and the overall administration is carried out by using parallel construction under coordinating meta controlling command. The intellectual technique of overlaying hidden lines developed by plotting and patching up automatically part drawings into an assembly drawing and the method of parametric alternate draft improve greatly the processing capacity of the system.
