Abstract

The paper proposes a system for monitoring surface wheel-grinding by analyzing the dynamic alterations in output variables and the process system state parameters. It analyzes the intervals of the process system state parameter interrupts. State space analysis was employed to describe the behavior of the grinding process system. The dependencies obtained enable a complete description of how the system behaves at any interval of the main interrupt period. The analysis of such behavior is reduced to sequential calculation of its parameters at times t 1 , t 2 , …, ti at interrupt intervals T 1 , T 2 , …, T N . The proposed state space analysis method enables an independent evaluation of output perturbations. Besides, by analyzing the dependencies we had obtained, we concluded that for such evaluation, one would have to calculate not only the absolute values of output variables, but also their first and sometimes even second derivatives.

Summary

Problem statement

One current trend in mechanical engineering is that assembling joints are becoming considerable more accurate. One can machine a shaft in 30 or 40 seconds using a conventional machine, while it takes 100 to 120 seconds when using a CNC machine This is due to the considerable alterations in the process system state that occur in machining. Despite a significant amount of known research, automated grinding machines are not utilized to their full capacity This is due to the great impact process system parameters, altering during the machining process, have on both performance and quality. To ensure the required quality while keeping high performance in grinding operations, one has either to stabilize the state of the system or to control the process by means of the diagnosis data that factor in the alterations in the process system. When CNC-machining a workpiece, the second approach requires an evaluation of alterations in the process system parameters
