Azarova N. Providing of parameters of roughness of grinded surface taking into account the radial vibrations of grinding wheel.

An object for study is a process of the flat infeed diamond grinding of hard-to-cut materials. A purpose is providing of set-up parameters of roughness of the grinded surface taking into account the radial vibrations of grinding wheel. Methods - theoretical methods based on fundamentals of theory of cutting, mathematical modeling, experimental methods. Research results and novelty - it is developed the mathematical model of process of the flat infeed grinding with the radial vibrations of grinding wheel, on the base of which the influence of parameters of vibrations on the amount of contacting grains, form and sizes of cuts is researched; the method of determination of parameters of roughness of the machined surface is developed taking into account the radial vibrations of grinding wheel, this method includes the calculation of the mechanical conditions, providing required parameter of roughness. It is developed the recommendations on grinding conditions of hard-to-cut vanadium steels for using in industry. Industry is machine-building plants of Ukraine.
