Construction of Smart CNC for Real-Time Optimization of Milling Parameters

智能数控机床是"工业4.0"时代下智能化工厂的生产终端设备,其网络化、智能化以及协同制造技术的实现离不开高稳定性、高精度保持性的开放式智能数控系统。以实现铣削过程中切削参数的实时优化为目标,在具有开放式模块化的数控系统平台上设计并开发了可实现该功能的软件模块。在数控系统的系统协调模块中集成了智能控制算法,该算法可根据切削过程中实时采集的切削力信号实时调整主轴转速和进给速度,最终通过薄壁件切削试验验证了智能数控系统功能的有效性。

Intelligent CNC machine tool is production terminal equipment of smart factory in the era of Industries 4.0. Technical implementation of network, intelligence and collaborative manufacturing of this machine tool can not do without open smart CNC which has high stability and precision retaining ability. In this paper, aimed at real-time optimization of cutting parameters during milling process, functional software modular is designed and developed in the platform of open modular architecture CNC. The algorithm of intelligent control is integrated into system coordinator modular of CNC, which could adjust spindle speed and feed rate in real-time through processing cutting force signals. The effectiveness of proposed smart CNC is validated by thin-wall cutting experiments.
