Title:
TOOL REPLACEMENT RECORD-BASED CUTTING TOOL LIFE SETTING METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/223965
Kind Code:
A1
Abstract:
A cutting tool life setting method, relating to the technical field of cutting tools, comprising: obtaining at least two groups of previous cutting parameters of a cutting tool (110); for each of the obtained at least two groups of previous cutting parameters, obtaining at least two tool replacement records of the cutting tool when the group of previous cutting parameters is used (120); fitting the failure time distribution of the cutting tool on the basis of the at least two tool replacement records of the cutting tool when the group of previous cutting parameters is used (130); receiving a group of predefined cutting parameters of a target cutting tool (140); and setting the tool life of the target cutting tool according to the group of predefined cutting parameters, the at least two groups of previous cutting parameters, and the failure time distribution corresponding to each group of previous cutting parameters (150). Compared with a conventional cutting tool life setting method, the method allows the optimal life of the target cutting tool to be set under a newly defined cutting parameter set that has never been used.
