摘要
具有薄壁结构的关键航空零部件在切削过程中不可避免发生颤振现象。为提高工件表面质量,在加工过程中对颤振进行准确识别和有效控制已成为该领域的主要研究方向。而对于颤振在线辨识和抑制功能的实现,必须开发集成先进传感器和智能控制算法的智能数控系统,并保证系统中各功能模块线程协调运行。因此,在航空薄壁件的精密加工过程中,利用智能加工技术对切削颤振进行实时辨识和在线抑制将成为未来数控加工技术的发展趋势。
Cutting chatter is an inevitable problem during machining for many key aerospace components which have thin-walled structures. To improve quality of workpiece effectively, chatter recognition and control in machining process has become the main research direction in this field. For realization of on-line chatter identification and suppression, a smart CNC system which combines advanced sensor and intelligent control algorithm must be developed, and coordinate operation between different threads of function modules should be guaranteed. Therefore, in the process of precision machining, to identify and suppress chatter by using intelligent processing will become the future trend of CNC machining.
