In end milling operations, the tools are exposed to high temperatures and high pressures, which inevitably causes the tool wear progress. It is well known that the tool wear progress strongly depends on the temperature of cutting edge. In this study,

In mass production, the tool life of cutting tools is generally controlled by the number of parts to be machined and the machining time, making it difficult to operate each tool to its full life. In addition, it is desirable to avoid tool changes due
