基于机器视觉的开放式复杂轮廓曲线磨削数控系统

摘要

Based on the introduction of a principle of numerical profile grinding method,this paper develops a kind of open CNC system.The hardware and software structures were constructed.The CNC multithreading mechanism was analyzed.The fusion of numerical control with image processing,and the compensation of machining error based on visual axes were discussed.Finally,the simulation experiments were conducted.The results verified the feasibility of the open CNC control system.%介绍了一种数字化曲线磨削的工作原理,提出了基于机器视觉的开放式复杂轮廓曲线磨削数控系统的设计方法,建立了开放式数控系统的硬件和软件结构,分析了数控系统的多线程机制、人机交互与图像处理融合、基于虚拟轴的加工误差补偿等重要特征,最后试验验证了曲线轮廓轨迹控制和误差补偿的可行性.
