Dynamics of the system for feed kinematical chain hydrostatic driving

Abstract

Transitory phenomena affect the machine tools with hydrostatic driving functioning, during their exploitation. Finding out the laws that give the dependence between the driving system hydraulic parameters variation and the machine tool operational parameters values is the target of the studies concerning these transitory phenomena. The longitudinal feed kinematical chain of the plain grinding machine was analyzed for this purpose. The machine tool structural scheme was considered in relation to the transfer functions specific to each component. The longitudinal feed slay dynamical driving system characteristics were also determined. This way, the premises for establishing the interdependence between the hydrostatic system functional parameters were created, aiming to reduce the transitory phenomena negative influence onto both machined surface quality and machine tool productivity.
