1. A method for operating a machine tool system, the machine tool system comprising a machine tool with a tool for machining a workpiece, and a control apparatus connected to the machine tool for generating a relative movement between the workpiece and the tool using a program which can be executed by the control apparatus, with the control apparatus comprising an operating facility with a display apparatus for interaction between an operator and the control apparatus, said method comprising:
altering manually by the operator using the operating facility a technology parameter;
determining a change to a production-related characteristic variable brought about by the altered technology parameter;
displaying the changed production-related characteristic variable on the display apparatus directly or in relation to an associated relative measure;
determining the changed production-related characteristic variable with the control apparatus or with an external computing facility connected to the control apparatus;
storing in the control apparatus or in the external computing facility a tool change time provided for a tool change or tool costs required for procuring the tool or a machine hour rate associated with operating the machine tool; and
determining a measure for the change to the production-related characteristic variable as a function of at least one of the tool change time, the tool costs and the machine hour rate.
