Telegin O. Increasing the effectiveness of face grinding hard-to-machine materials process at the expense of kinematics

Object - process of grinding of flat surfaces hard-to-machine materials; investigation subject - heightening of efficiency and an exception of thermal imperfections of flat face grinding hard-to-machine materials; methods - fundamental positions of the theory of grinding of materials, theories of influence of surface-active substances on abrasive processes, mathematical and computer simulation; results - are developed kinematic configurations of epicyclic grinding devices which ensure lowering of power and power indexes of process and eliminate probability of origin of thermal imperfections; the technique of definition of area of rational is constructive-technological parameters of process of face epicyclic grinding is offered; Novelty - the hypothesis about possibility of the directed regulation of the sizes, trajectories and speeds of relative movement of a grinding area by change of an angle of inclination of an axis of rotation of a circle and a parity between angular velocities of making working-class movements is advanced and justified; it is offered and experimentally the new circuit of epicyclic grinding with additional rotation of a grinding head is examined, influence of conditions of handling and cutting conditions on process indexes is examined; are defined rational constructive and technical characteristics for ways of flat epicyclic grinding; Introduction - SE Zaporozye Motor Design Bureau «Ivchenko-Progress» (Zaporozye), SE Scientific-Manufacturing Complex Gasturbinconstruction "Zorya-Mashproekt" (Nikolaev); area - machine building.
