The mathematical model of self-oscillatory process is offered at processing of deep apertures which has allowed investigating influence of various factors on intensity of vibrations and stability of system. Taking into account results of theoretical researches designs of boring tools with the raised stability to vibrations have been developed. Experimental researches have confirmed adequacy of mathematical model and have allowed planning ways of increase of stability, quality and productivity of processing.</p>Self-oscillationsmathematical modelmachinetooldetailprocessing by cuttingboring toolsАвтоколебанияматематическая модель вибрацийстанокинструментдетальобработка резанием расточные инструменты
