开放式智能制造控制系统的两个关键模块设计

摘要

开放式智能加工技术促进了铣削过程实时检测和控制技术的发展和应用。具有可操作作性、可扩展性等优点的开放式数控系统，为融合智能策略搭建智能加工系统奠定了基础。
　　本课题旨在设计一个使铣削过程中的切削力保持恒定的开放式智能控制系统，重点是切削力数据采集系统和控制策略的设计。切削力由测力仪采集，经模拟放大后输入研华PCI 1710数据采集卡，由数据采集卡对采集得到的切削力模拟信号进行A/D转换。基于VC编写的数据采集程序将X、Y、Z向切削力和其合力在计算机上实时显示，并作为反馈量输入模糊控制器。应用模糊控制策略，对比实际切削力和预设切削力，实时改变切削进给速度，已达到使切削合力恒定的目的。
　　利用Matlab对模糊控制策略得到的进给量和获得的切削力进行了仿真，仿真结果表明，模糊控制算法通过调整切削进给速度成功地控制了切削力，使其接近于预设的切削力。该控制系统的在铣削加工中的应用可以提高工作质量和系统响应，消除人为错误，减少停机时间和维修费用。相对于封闭式数控系统，在开放式系统架构中应用模糊控制策略来监测和控制铣削过程，具有灵活性高、适应性强、系统整体一致性好和便于升级和改进等优点。
