Abstract
A method is provided for monitoring a milling method for a milling machine provided with a milling tool comprising cutting teeth, the method including: determining measured values of a first parameter corresponding to a bending of the milling tool as a function of a second parameter corresponding to an angle of rotation of the milling tool in a rotating frame of reference of the milling tool and analyzing the measured values as a function of at least one monitoring criterion.
Claims7
A method for monitoring a milling method for a milling machine provided with a milling tool comprising a plurality of cutting teeth, wherein the milling tool rotates about a tool rotation axis during the milling method, the method for monitoring comprising:
- measuring values of a bending moment of the milling tool as a function of an angular position of the milling tool in a rotating frame of reference of the milling tool, the rotating frame of reference being a frame of reference representing angular position about the tool rotation axis;
- analyzing the measured values of the bending moment as a function of at least one monitoring criterion;
- and
- issuing an alert to replace the milling tool when the at least one monitoring criterion is greater than a predetermined threshold for the at least one monitoring criterion,
- wherein one of the at least one monitoring criterion corresponds to:
- an offset, the offset being a value representing a change in angular position of a maximum measured value of the bending moment for at least one of the plurality of cutting teeth, the change in angular position being an angular shift from a first angular position of the milling tool in the rotating frame of reference of the milling tool at which the maximum measured value of the bending moment is measured prior to the milling tool having any defects from milling to a second angular position of the milling tool in the rotating frame of reference of the milling tool at which the maximum measured value of the bending moment is measured after the milling tool has been used for milling for a period of time.
