Abstract
The paper deals with the dynamics analysis of the developed by the authors three edge head with elastic guides and electromagnetic drives in order to compare their operation dynamic features against the single tool machining ones. The three edge heads of proposed design of adaptive type have the possibility of adjustment to the changing cutting conditions. The adjustment of the head cutting edges positions in the process of machining is performed by two-direction electromagnetic drives with microcontroller based on intellectual control. So the simulation theoretical model was developed in a form of calculating scheme and the differential second order equations set. These equations are being solved using the software techniques and computer program graph interpretations. Thus the diagrams illustrating the oscillograms of the work piece and the head cutting elements vibrations in the machining process were obtained. The results of the investigation make possible to testify the developed three edge head productivity and dynamic accuracy increasing as compared with that of the single tool machining. They show that in most cases it is possible to increase the dynamic accuracy of machining in 1,2-5 to 3,17-9,6 times.
