1. A method for the correction of tool parameters of a machine tool for machining workpieces, comprising:
recording measurement values of measured characteristics as actual values of at least one workpiece machined with the machine tool;
comparing the measurement values with default set values of the workpiece, wherein the measurement values that are recorded relate to at least one of:
at least two measured characteristics;
at least two parameters of at least one measured characteristic; and
at least one measured characteristic and of at least one parameter of the same or one of another measured characteristic;
calculating an average for a tool correction value from the measurement values and associated set values; and
correcting the machine tool using the tool correction value,
wherein a weighted average for the tool correction value is calculated from the measurement values; and
wherein the measured characteristic and/or the parameter with the smallest tolerance is used most strongly in calculating the weighted average.
