Identification of the lathe module dynamic condition according to the stochastic characteristics of cutting

The purpose of the work: improvement of the surface quality during the lathe work on the base of the identification of the machine tool dynamic conditionaccording to the stochastic characteristics of the technological system vibroacoustic oscillations during cutting. The method of the lathe module dynamic condition on the base of linearized (according to the autocorrelation function) vibroacoustic oscillations of themodel of the elastic system transmission function, integral estimations of the autocorrelation function and energy spectre, has been grounded. Realized has been the method of the identification of the lathe module dynamic condition, ensuring the reduction of losses from the rejection in average by 20%, and increase in the machine tool operating coefficient according to the control program in average from 0,55 to 0,56. The method of identification of the lathe module dynamic condition ensuring the maximum accuracy of the surface treatment has been put in service.
