1. A system for utilizing an identification marker on a tool part for a cutting tool for determining a tool wear of the tool part, the system comprising:
a camera for obtaining image data and reading a unique machine readable code;
an electronic device configured to be connected with the camera, the electronic device having a processing circuitry configured to cause the system to:
detect, by the camera, the identification marker at the tool part, wherein the identification marker is the unique machine readable code;
read, by the camera, the unique machine readable code of the identification marker;
obtain, from the unique machine readable code, individual dimension information data including at least one individually measured dimension associated with the tool part as measured when manufacturing the tool part;
obtain, by the camera, image data of the tool part;
obtain current dimension information data of the tool part including at least one current dimension associated with the tool part by performing image processing of the image data of the tool part; and
determine tool wear data by comparing the current dimension information data with the individual dimension information data of the tool part.
