摘要
介绍了一种麻花低频复合振动钻削在线监控系统．该系统以刀具状态为主要监测对象，以切削力（包括轴向力和扭矩）为监测参数，具有预报刀具破损、监测刀具磨损，并在异常状态下适时地控制切削过程等功能．
One kind of monitoring and control system for twist drill running in low frequency vibration is introduced. With status of cutting tool as primary monitoring object and cutting force(involed axial force and torque)as monitoring parameter the system can predict tool wear, monitor tool breakage, control cutting process in realtime under abnormal conditions,and so on.
