The invention discloses equipment for monitoring the drilling state of a bone material and a using method. The equipment comprises a Z-direction feeding mechanism, an XY-direction moving mechanism, a dynamometer, a bone material clamping mechanism, a displacement sensor, an industrial camera, a dynamometer and an acoustic emission signal sensor. A computer is used for controlling an industrial camera to move to the position under a drill bit, a cutting edge image is collected, the rear tool face abrasion loss is measured, a displacement sensor measures the actual feeding distance of the drill bit, and a dynamometer collects force signals in the X direction, the Y direction and the Z direction in the drilling process in real time; acoustic emission signals in the drilling process are collected in real time through an acoustic emission signal sensor installed on a bone material clamping mechanism, and a rear tool face abrasion loss prediction model is established according to the collected various signals.
