Method for determining a degree of wear, device for determining a degree of wear, machining device and computer program

A method for determining a degree of wear of at least one component of a machining device, wherein at least one actual condition of the machining device is established and the at least one actual condition is compared with at least one comparative condition of the machining device and a conclusion is drawn as to the degree of wear of the at least one component as a function of a determined deviation between the at least one actual condition and the at least one comparative condition, wherein to establish the at least one actual condition and/or the at least one comparative condition, sound emissions of the machining device are captured, wherein at least one operating parameter of the at least one wearing component is determined from the captured sound emissions as a tool-specific operating parameter of a machining tool of the machining device, wherein the at least one tool-specific operating parameter is determined from the captured sound emissions by establishing a gear mesh frequency fz of the machining tool and/or a harmonic of the gear mesh frequency fz,i of the machining tool, and wherein the at least one actual condition and/or the at least one comparative condition being established using the at least one operating parameter.
