Abstract
The article describes the solution of the problem of increasing the efficiency of a circular grinding with CNC by applying a model of processing accuracy prediction which considers the multi-stageness of the circular grinding process with axial feed during designing and optimization stages of control cycles for the radial and axial feeds. High productivity of external circular grinding operations with axial feed is ensured by simultaneous control of automatic stepwise cycles of radial and axial feeds in different sections of the shaft.Computed models have been developed; for given grinding cycles of radial and axial feed they allow to determine values of all main error types which are caused by the presence of initial radial run-out of the billet and elastic deformations of the technological system in three shaft sections (in reverse and non-reverse zones): diameter error, circularity deviation, radial run-out, cylindricity deviation, longitudinal section profile deviation, and total radial run-out.
