Purpose: This article mainly describe the reliability of the cutting tools in the high speed turning by normal distribution model. Design/methodology/approach: A series of experimental tests have been done to evaluate the reliability variation of the cutting tools. From experimental results, the tool wear distribution and the tool life are determined, and the tool life distribution and the reliability function of cutting tools are derived. Further, the reliability of cutting tools at anytime for high speed machining (HSM) is easily calculated from cutting parameters and tool wear limit from the derived reliability function. Findings: The higher the cutting speed, the sooner the tool flank wear, and the faster the degrade speed of the reliability curve. It means that the sooner the tool flank wear rate, the shorter the tool life, and it is the time to change the cutting tool. Practical implications: This paper shows that the tool flank wear rate can be described by the reliability degrade rate, the higher the flank wear rate, the steeper the tool reliability degrade rate. Originality/value: This article is discussing about the tool wear variation of the cutting tool from the point of reliability. From the reliability variation of the cutting tool, we can further predict the tool life, in order to decide the tool replacement time.
