When the high-speed cutting, should determine a reasonable tool wear life (limit) according to the processing method and processing requirements. High-speed cutting tool wear life affect many factors, such as the workpiece material and tool material matching cutting mode, tool geometry, cutting the amount of coolant, vibration tool wear life has a significant impact and influence of its specific cutting conditions, the effect should be to determine the effects of all relevant factors on the tool wear life by cutting tests. Here are a few examples of high-speed machining and the corresponding tool wear life.

     High-speed machining of cast iron

     High-speed machining of hardened steels

     High-speed machining of nickel-based alloys
