Обеспечение точности обработки на операциях шлифования

Abstract

The paper presents a theoretical analysis ofthe technological capabilities for improving the accuracy and efficiency of processing by grinding circuit with initial interference in the process system, i.e. the schemes used in the nursing practice. For this purpose an analytical solution of the problem of determining the magnitude of the elastic displacement when grinding with an initial predetermined inter-ference in the process system is obtained. It is shown that the value of the elastic displacement decreases exponentially in time, taking the values corresponding to the conditions of high-precision machining. The time of processing required to achieve the desired (target) accuracy is determined. This allows to determine scientifically by calculation the optimumprocessing parameters based on the requirements on the accuracy of the machined surface.
