Time Varying Parameters

To reduce the error in the appointment of the mode in the conditions of uncertainty of information for the first time developed mathematical models and algorithms that provide for the correction of the model parameters relating the input and output parameters of the process, according to the current information about the output parameters. Developed a plan of varying the controllable factors of the technological process, the methodology and the algorithm used to generate mathematical models of the machining process with time-varying parameters. Models take into account the mutual influence of the tool state parameters and the current processing parameters and their impact on the output parameters and allow you to calculate the output parameters of the process at different times. This makes it possible to create prerequisites for the purpose of machining mode with time-varying parameters in the conditions of uncertainty of technological information.

Abstract This paper presents a new method, multiple time-varying parameter (MTVP) turning for chatter suppression. Compared to the single time-varying parameter (STVP) turning, the new method uses both time-varying spindle speed and time-varying rake angle to suppress chatter. The paper provides theoretical analyses on the MTVP turning and experimental results to justify the analytical results. It compares the effects of chatter suppression between the MTVP and STVP turnings, and discusses the possible mechanisms of chatter suppression. The paper then concludes that the MTVP turning method is more effective in chatter suppression than the STVP turning method because of the combined effect of the multiple time-varying parameters. It is demonstrated that the MTVP turning method can suppress chatter by 80%, and can be applied to suppress all kinds of chatter in a machining process.
