摘要
以数控铣削加工为研究对象,以主轴负载恒功率为约束条件,用模糊智能控制方法实现进给速率的在线调整.详细讨论了模糊控制器的设计,包括隶属度函数的改进,模糊推理方法的选择和输出比例因子的在线调整方法,开发了基于主轴功率信号反馈的智能控制器,在FANUC数控系统上进行实验,结果表明设计的智能控制系统与数控系统具有较好的相融性,完全达到了提高切削效率,保护刀具的目标.
The paper presents a research of integrating adaptive control with a standard computer numerical controller（CNC）for optimizing a metal-cutting process. The design adaptively maximizes the feed-rate subjected to allowable cutting power on the tool by avoiding excessive tool wear and tool breakage to maintain a high chip removal rate. The system consists of a basic fuzzy logic controller, a fuzzy rule base and a tuning mechanism. The tuning mechanism helps to enhance the adaptability of the system. Actual industrial tests show a higher machining efficiency and good tool protection.
