文章通过对铁路货车车轴的数据分析,得到了绘制该类型车轴的共性参数,并借助Au- toLISP语言进行了AutoCAD的二次开发。实现了AutoCAD平台下铁路货车车轴的参数化设计,使计算机能自动生成零件图形和输出数控程序所需的基点坐标。
Through the data analysis of railway wagon axles, the article obtained the common parameters of this kind of axles and carried out the secondary development of AutoCAD with Au-toLISP language. Realized the parametric design of railway wagon axles under AutoCAD platform so that the computer can automatically generate the part drawings and the base point coordinates required for outputting NC programs.
