Abstract
An on-machine monitoring system for the failure state of the rotating tool and a detection method thereof are provided. The monitoring system includes a detector, a data processing controller, a tool data server, and a Hall current sensor. A tool diameter and a tool length are determined according to image sequences of a tool. A wear state and a breakage state of the tool are determined according to the tool diameter and the tool length. A spindle current signal is acquired by the Hall current sensor. And an edge chipping state and a breaking state of the tool are determined according to the spindle current signal.
