单片机在机床刀具过载保护与自动调整过程中的应用

The Application of Single Chip Computer in Lathe Cutter's Overload Protection and the Process of Automatic Adjust

由于目前机床的过载保护一般只能保护电动机的过载 ,不能保护刀具的过载。因此 ,本文采用单片机实现对刀具过载保护的控制线路。保护信号取自主回路电流 ,线路能自动、实时地监测此电流 ,当它超过额定值时即报警 ,继续增加就立即自动停车。

Because the traditional lathe's overload protection can only protect the motor.It always fails when the cutter's overloads.By the single chip computer,the protection signal are gotten from the current in the main circuit,When the current value is larger than the rating,the center will give an alarm.If the current continue to increase,the center will cut the main circurt and the motor will stop then.
