This invention provides a circular microphone array system and method for monitoring bone milling angle and depth based on milling sound, belonging to the technical field of surgical instruments. The system includes a microphone clamp with an even number of microphone component slots. At each end of the microphone clamp is a claw that secures it to a cutting tool.
