用ObjectARX开发MDT快速准确地计算冲模的冲裁力

通过利用计算机图形学和计算机数据结构的基本原理，以Visual C 6．0和ObjectARX2000为开发工具，对MDT6．0进行二次开发，就可不必区分单个图形，而是把所有的直线、圆或圆弧都看作一个个特定的对象，然后再对它们进行分类处理，分别提取它们的图形信息并计算出所需要的数据，并利用这些数据计算出冲模的冲裁力。只需进行简单、直观的操作就可以快速准确地求出各种复杂形状冲裁件、多凸模冲裁件的冲裁力，解决了冲模的冲裁力计算困难的问题，为以后的模具设计做好了必要的准备。

Developing MDT6.0 with ObjectARX for quick and accurate stamping force calculation of dies

If we utilize the basic principle of Computer Graphics and Computer Data Construction and understand the internal data construction of entity in the software, we need not make any difference among each graphics and see them as particular object.Then we classify them , pick up the graphics information , calculate the needed data and stamping force of stamping dies by developing MDT 6.0 with Visual C++ 6.0 and ObjectARX 2000.Thus we can calculate stamping force of all kinds of dies of complicated shape and many males dies quickly and accurately, which only needs to do some simple and visualize operation.The method solves successfully the question that the stamping force of dies is difficult to be calculated.It is very useful for the future dies design.
