目前自动编程系统还需要人工参与一定量的工作,CAD系统所生成的零件几何信息尚不能为自动编程系统所接受。信息流在这里被阻断。本文提出的全自动产生NC加工轨迹的方法,是利用用户在CAD阶段输入的描述加工零件几何形状的源程序,经由几何造型系统(CTIPS)处理建立公用几何数据库(GDB),在此基础上利用罚函数法计算刀具位置数据,并经后置处理得到数控指令格式(程序单)的穿孔带,可直接提供给数控机床加工零件用。本方法中采用“软件传感器”有效地解决切削中可能出现的干涉问题。根据本方法原理已编制成CAM01软件包,在CTIPS系统支持下,在VAK11/780超小型机上运行
At present, the automatic programming system also needs human participation in a certain amount of work. The geometric information generated by the CAD system can not be accepted by the automatic programming system yet. The flow of information is blocked here. In this paper, a fully automated NC machining trajectory generation method is based on the use of the user input in the CAD stage to describe the geometry of the machined parts, the establishment of a common geometric database (GDB) via the Geometry Modeling System (CTIPS) Penalty function method to calculate the tool position data, and after the post-processing CNC command format (program sheet) perforated belt can be directly provided to the CNC machining parts. The method used in the “software sensor” effectively solve the cutting interference problems that may arise. According to the principle of this method has been compiled into CAM01 software package, with the support of CTIPS system, run on VAK11 / 780 minicomputer
