Lutsiv I. The fundamentals of development of multiedge accessories with intertool links for surfaces of revolution machining

The thesis deals with the scientific fundamentals of development of multiedge accessories with kinematic intertool links (KITL) for surfaces of rotation machining as a base for structural performance and rational design and operation running of progressive machine tool systems for essentially increase of productivity, accuracy and quality of machining coparatively with traditional cutting. On the base of using of kinematic adaptive links between cutting elements the complex of new kinematic and technological schemes of selfadjusting machining of parallel, leaning and oncoming turning, adjust drilling, countersinking, boring and combine cutting are developed and structural formulas and design arrangements are given. The essential possibility of decrease of selfinduced vibrations set in while multiedge machining with KITL is prescribed. The approximation analytical formula of calculating of dynamical stability limit of multiedge machining is given and the operation modes of nonresonance machining with variable depth of cut are prescribed. The results of investigation of kinematics of cut elements formation are given and the structural sythesis of new design arrangements schemes of accessories for kinematic breaking up of cut are developed. The operation characteristics of multiedge machine tool accessories with KITL are investigated. The methodology of developing of multiedge accessories realized in the algorythm of structural and parametric synthesis and analysis is given.
