For efficient metal cutting, machining data, tools and cutting conditions are the three major elements. These determine the machining time, tool life and machining quality. An economical and effective machining method must be a reasonable choice of cutting conditions. Three factors of cutting conditions: cutting speed, feed rate and depth of cutting directly cause tool damage. As the cutting speed increases, the temperature of the tip increases, and mechanical, chemical, and thermal wear...
