摘要： <正>MAPG——具有绘图仿真功能的三座标数控铣床自动编程系统。它专门解决工业化生产中多座标数控机床加工零件程序编制问题。 本系统在图形处理上抛弃了传统的解析定义法,采用了有向图和多面投影的定义方法;采用向量计算法,简化各种复杂型面的几何计算,提高了计算精度;在数控语言中引进了算术表达式并把它扩充成几何表达式;在绘图处理中,采用了齐次变换矩阵的简明算法。 MAPG系统是在Z-80微机上实现的。至今该系统已经成功地完成了几十种复杂零件的自动编程问题。

Abstract: MAPG-the 3-D numerical control automatic programming system is essentially used to solve the problem of programming on multiple-coordinate numerical control miller processing parts in industry. Instead of traditional analystic definition method in graphic processing. the system utilises the directed graph and rnutli-plane projection as its definition method. The vector computational method has also been adopted so that it has reduced the geometric computation complexity for various complicated planes, and on the other hard,increased the computational accuracy. Arithmetic expression used in the numerical control language has been further extended into geometric expression, and simple algorithmof homogeneoust ransformation matrix has been applied to graphic processing. MAPG has been implemented in Z-80. Tens of automatic programming tasks for complicated parts have been successfully completed so far by using the system.
