数控旋压机专用数控系统的研究

为解决目前我国封头旋压工艺无法同时实现自动化、系列化、高精度、高表面质量等问题,将开放式数控技术应用到封头旋压机床中。首先开展了以封头旋压力模型为基础的旋压轨迹规划的分析,建立了旋压数学模型及封头旋压机数控系统之间的关系,提出了基于工控机IPC和运动控制卡的开放式系统开发方法,该系统充分利用Windows丰富的软件资源及面向对象的编程语言Visual C++6.0,最后对搭建的开放式旋压机数控系统进行了性能测试。研究结果表明,该开放式封头数控旋压机数控系统运行稳定,基本实现了总体设计要求。

Research of the special numerical control system of CNC spinning machine

In order to solve the problems of our head spinning craft unable to realize automation, serialization, high precision and the best surface quality,the open numerical control technology was applied to the head spinning machine. After analysis of spinning trajectory planning based on the head spinning force model, the connection between spinning mathematical model and the head spinning machine CNC system was established, and the method of the open systems development based on the industrial personal computer（ IPC ） and motion control card was presented. The spinning machine CNC system had made full use of the rich software resources on the Windows system and Visual C ＋ ＋ 6. 0. The building CNC system was tested and evaluated. The experimental results show that the CNC system is stable, and it realizes the overall design requirements.
