1. A method for the control of a machine tool with a tool magazine for tools, of which the machine tool can hold one at any time for machining a workpiece, wherein the method comprises the following steps:

  • registering workpieces to be machined;

    grouping registered workpieces into set-up families in such a way that a set-up assigned to the set-up family is sufficient to machine the workpieces of the set-up family;

    wherein the set-up comprises tools which can be loaded simultaneously in the tool magazine;

    wherein the set-up families are formed in such a way that the number of tools that are to be loaded for machining the registered workpieces is minimized as far as possible,whereina plurality of workpieces of the same type are grouped to form one order and the set-up families are formed in such a way that the expression (M−

    E)*O is maximized as far as possible over all the workpieces of all the set-up families;

    wherein M is the number of tools that must be loaded for machining the workpiece;

    E is either zero or the number of tools that must be loaded exclusively for machining the workpiece;

    and O is the number of orders registered altogether for the workpiece.
