Abstract

Shaping of surfaces during finish machining using intermittent abrasive tools requires optimized technological systems design and parametrization. To achieve that, theoretical base including equations of motion for discontinuous grinding and calculation of forced vibrations of elastic technological systems is implemented. Approximation of radial component of cutting force provides ability to study the dependence of amplitudes and phases of oscillations of technological system under the action of k-th harmonic of disturbing force. Direct correlation between the surface layer shape errors and the parameters of forced oscillations was observed.
