Abstract
The article analyzes the results of modeling dynamic processes during circular grinding of parts. Models are presented in the form of experimental dependences of the vibration amplitude on the grinding time; models of the process of interrelation of cutting forces and control actions; the obtained function of dynamic accuracy, which characterizes the trajectory of motion and relative oscillations of the grinding wheel and the part; models for assessing the influence of the value of an adjustable normal grinding force on the course of radial wear of a grinding wheel, volumetric productivity and basic grinding time, surface roughness of a part processed by wheels with different characteristics. Models of external cylindrical grinding in the form of a set of differential equations characterizing the dynamics of displacements of the centers of the wheel, workpiece and changes in the actual depth of cut are most acceptable for use in the implementation of stochastic observation and filtration procedures. They are taken as a basis for stabilizing the parameters of the technological system, taking into account the effects of equipment and the external environment (waves of the water surface) on the machine in floating workshops.
