【摘要】 利用7轴5联动数控系统的PLC(可编程逻辑控制器)资源,提出了数控系统与自适应控制技术集成的方法.它直接获取伺服模块的切削负荷特征信号,无需外加传感器,实现了切削负载的自适应控制,并根据加工过程的实际情况设计模糊控制器.控制器应用于螺旋桨的加工过程.结果表明,采用的控制策略能适应复杂工况的变化,稳定地控制加工过程,达到保护机床、刀具和提高加工效率的目的.更多还原

【Abstract】 NC(numerical control) system is integrated with adaptive processing technology by using the PLC(program logic controller) of 7-axis NC system.In this integrated method,the cutting load signal is acquired from the motor driver servo without sensors to implement cutting load controlling;the fuzzy controller is designed according to the actual process.The validity is verified by processing propeller.The experiment indicates that the controlling process is stable,while the tools and machines are protected and the efficiency is improved.更多还原
