Run time and cutting capacity for creep-feed grinding by cone wheel

Creep-feed grinding is most widely used in the processing of complex profile surfaces. Given that any generator of profile can be represented as a broken straight line, the study of the process of grinding by a conical profile wheel is of considerable scientific and practical interest. Kinematic mathematic models for the run time, cutting and instantaneous cutting capacity for the penetration, constant length of arc and exit stages have been developed for surface creep-deep grinding by conical profile wheel. Mathematical models are approximated by incomplete polynomials of 5–4 degrees with single ratio coefficient. This approach simplifies mathematical processing of the results when using the reliability factor in the subsequent mathematical models for the creep-feed grinding process. The change patterns of the reliability factors and the characteristic points of the process have been determined during the grinding stages. The effect of the grinding modes and the wheel size on the characteristics of the process is shown. The article describes the correlation between the parameters, and the dependence of their maximum values on the studied factors. ю обработку результатов при использовании показателей безотказности в последующих математических моделях процесса глубинного шлифования. Определены закономерности изменения показателей безотказности за время шлифования на этапах и характерные точки процесса, показано влияние режимов шлифования и размеров круга на показатели процесса. Установлена взаимосвязь между параметрами, а также зависимость их максимальных значений от исследуемых факторов.
