Abstract

A method is proposed for controlling tool change operations on a machine tool, wherein a machining procedure on a workpiece includes a sequence of machining operations having in each case a particular tool and in each case a particular duration, and for a tool change, tools of a tool spindle are provided by a second storage device in communication with a first storage device, and wherein there is associated with the machining procedure a sequence of tool provision operations in which a tool provision operation has in each case a particular duration, wherein the method includes a determination stage wherein the durations of the machining operations and the tool provision operations are determined, and a control stage wherein the tool provision operations are temporally grouped in relation to the machining operations such that the tool provision operations bring about a minimized idle time in the machining procedure.
