The mandrel taper errors connected with its manufacture may be added by the operation errors emerging as a result of wearing out caused by friction in the mating conical surfaces. Depending on the ratio of deviations from parallelism and alignment of mandrel taper and spindle socket and their directions, the initial tool carrier contact may occur at the point of a large spindle socket diameter (intensive wearing out of the mandrel taper bottom part and the spindle socket) or at the point of a small diameter of the mandrel taper (intensive wearing out of the upper part of the mandrel taper and the spindle socket). The formation of the friction path will depend on the initial contact of the mandrel taper and the spindle socket. The result of the study includes obtaining dependencies that allow determining the areas of intense wearing out and contacting pressures when using the automatic tool changer system, depending on the deviations of the mandrel axes and the spindle socket from alignment and parallelism at the moment of initial contact determined by the auto operator’s work errors.
