The hypothesis that high frequency vibration of a dynamic disk system is excited by a rotating roller is verified. The information content of the vibrational signal is determined. The characteristics of the vibrational signal are compared with the rotation characteristics and the machining precision.

In the article the strategy and algorithm of technological control of the process of bilateral abrasive processing of cylindrical bearing rollers are considered. The main variable control parameters of the process are the parameters of the angular position of the grinding wheels, the size of the removed allowance and the feed rate of the workpieces. As a result of complex theoretical and experimental research, control principles, criterial conditions, functional and parametric constraints are formulated. The solution of the problem of synthesis of control parameters is given. The effectiveness of the technological control is confirmed by production tests and is expressed in increasing the accuracy and productivity of processing rollers.
