【摘要】：随着数控技术的不断发展,开放式的数控系统已经成为了制造业发展前沿的代表。开放式数控系统是一种柔性化、可拓展、模块化的体系结构,这种结构可以给用户提供更多二次开发的空间,满足市场不断多样化的需求。数控系统日益开放化的发展趋势对数控技术人员的基本素质、实践能力、创新能力都提出了更高的要求。本文课题来源于特色名校建设项目—数控实验平台建设,针对于学校数控技术人才培养与企业生产实际脱节的现状,结合数控系统的基本原理,研究开发了一套用于数控技术教学、实验、二次开发的数控教学系统。本文首先分析了现代数控系统的发展现状,阐述了开放式数控系统实验教学平台研制的必要性。其次本文结合开放式数控系统的工作原理,构建了实验台的框架体系,确定了以PC机为上位机,运动控制器为下位机的主从式结构方案;并进一步对运动控制卡、伺服系统等硬件结构进行了分析选择。然后针对于学校教学的特点,以Windows XP系统为操作平台,采用面向对象的模块化编程思想,在Visual C++6.0的编程环境下结合运动控制卡提供的动态链接库,完成了人机交互界面、编程代码处理、零件加工轨迹仿真等功能模块的研究开发。最后提出具体加工实例,以实例完成对教学实验台的功能可行性的验证;并结合数控系统发展趋势,提出了对本文教学实验台的一些展望。
[Abstract]:With the continuous development of numerical control technology, open CNC system has become the representative of the manufacturing industry. Open CNC system is a flexible, extensible, modular architecture, which can provide users with more space for secondary development to meet the ever-changing needs of the market. The increasing development trend of numerical control system puts forward higher requirements for the basic quality, practical ability and innovation ability of numerical control technicians. The topic of this paper comes from the construction project of characteristic famous school-the construction of numerical control experiment platform, which is based on the current situation of the disconnection between the training of numerical control technical personnel and the actual production of enterprises, combining the basic principle of numerical control system. A numerical control teaching system for teaching, experiment and secondary development of numerical control technology is developed. In this paper, the development of modern numerical control system is analyzed, and the necessity of developing experimental teaching platform of open numerical control system is expounded. Secondly, according to the working principle of the open CNC system, the frame system of the experimental platform is constructed, and the master-slave structure scheme with PC as the upper computer and the motion controller as the lower computer is determined. Furthermore, the hardware structure such as motion control card and servo system is analyzed and selected. Then according to the characteristics of school teaching, taking Windows XP system as the operating platform, adopting the object-oriented modular programming idea, combining the dynamic link library provided by the motion control card under the programming environment of Visual C 6.0, the man-machine interface is completed. Programming code processing, part machining trajectory simulation and other functional modules research and development. Finally, a concrete machining example is put forward to verify the functional feasibility of the teaching experimental platform, and combined with the development trend of the numerical control system, some prospects for the teaching experimental platform in this paper are put forward.
