The invention discloses a method for adaptively controlling the spindle load of a numerically-controlled machine tool. By reading the spindle load of the machine tool in real time and changing the feed rate override of the machine tool, the feeding amount is adjusted in real time, thereby achieving the constant-load control of a machining process of the numerically-controlled machine tool, the purposes of balancing the cutting load, improving the machining efficiency, protecting the machine tool, and protecting a cutter and a clamp can be achieved, and the machining quality is better guaranteed. 本发明公开了一种自适应控制数控机床主轴负载的方法，通过实时读取机床的主轴负载，通过改变机床的进给倍率，实时地调整进给量，从而实现数控机床加工过程的恒负载控制，可以达到均衡切削负载、提高加工效率、保护机床、保护刀具和夹具的目的，更好保证加工的质量。
