Computer aided optimum design of machine tool spindle systems with hydrostatic bearings

Abstract

A general model of the spindle system with hydrostatic bearings is presented. In this model the whole system is divided into subsystems. Each of these subsystems is modelled in order to obtain an optimization considering the global criteria of the system. A four-stage multicriterion optimization strategy is applied to solve the problem. On the basis of this strategy, which has a heuristic character, a computer aided optimum design software package for spindle systems for grinding and lathe machine tools is developed. The software is supported by computer graphics. An example of designing a grinding machine spindle system is given.
