数控滚齿机参数化自动编程系统开发

为了提高齿轮加工效率,提出了一种基于滚齿加工的自动编程系统。在分析齿轮滚削加工工艺的基础上,建立了齿轮加工的数学模型,进而得到数控滚齿加工的NC程序。该方法仅需通过人机界面输入工件、刀具和工艺等参数,在工艺数据库和运算库的支撑下,即可自动生成NC程序。针对广州数控218MC数控系统,通过用户宏程序进行了自动编程系统的开发,实现了人机界面设计、滚齿算法设计和功能模块设计。最后,通过在工厂多台五轴滚齿机上的应用表明该系统编程效率高、加工零件精度高、算法可靠性强的特点,同时降低了机床操作人员的职业技术门槛,提升了国产齿轮数控系统的市场竞争力。

Development of an automatic programming system for CNC gear hobbing machine

In order to improve the efficiency of gear machining, an automatic parametric programming system based on gear hobbing is presented in this paper. The mathematical model of the gear hobbing processing was established. The core of the method is inputting certain parameters like workpiece, hob cutter and process parameters through human-machine interface, which automatically generates NC code of gear hobbing by parameter processing module in support of the operation and processing database. The design of human-machine interface, arithmetic, and functional module was realized by custom macro program based on GSK 218MC CNC system. The application in machine tools validates high programming efficiency, high manufacturing accuracy and reliability of the arithmetic, improving the utilization efficiency of the hobbing machine and decreasing the professional technical threshold for operators, but also promoting the market competitive power of the national produced gear hobbing CNC system.
