| description | Heightening of a chatter stability of boring process at turning is an actual problem. The basic circuit of a dominating vibratory system of process is developed for the theoretical analysis of oscillating processes for boring bars at boring process and the mathematical model of dynamic system of the lathe that allows us to define influence of design data of boring bars on a process of chatter stability is constructed. On the basis of mathematical model with use of transmitting function the influence of a direction of principal axises of rigidity of boring bar-slide elastic system on static characteristic of elastic tool system is determined. Experimental researches of boring bars have given the chance to define their frequency characteristics by a method of harmonic perturbation and to use them at boring process simulation. It is displayed, that ensuring of conditions of vibrational stability of internal turning on machine tools by boring bars can be carried out by a rational choice of their design data taking into account rational orientation of principal axises of rigidity of elastic tool system in relation to a direction of cutting force, a choice of a rational ratio of rigidity on these axes and heightening of damping ability of a cantilever part of boring bar. |
