镗削声发射信号与镗刀磨损量关系的研究

Abstract

Abstract: Theoretical analysis and experimental research are done for exploring the relationship between acoustic emission signal and tool wear on boring cutting process, and the relationship between values of characteristics concerning acoustic emission signal and the value of tool wear is obtained. In this paper it is suggested that the accumulative mean value t and the accumulative standard deviation σt, which are the accumulative values of maximum peak voltage Vpmax vs. t in a record length, may be used as real time and in-process recognition of values of characteristics for tool wear so that realizing prediction control for tool wear may be possible.

Key words: acoustic, emission, wear of borer, statistical characteristics
