ABSTRACT:
Disclosed is an optimizing method for regulating the operating state of a guided machine tool having a tool rotating at a certain speed and subjected to a percussion frequency during a boring action, in which the tool, subjected in addition to a force, is driven into an object of a given material. The method includes, determination of the parameters characterizing the actual operating state of the machine tool; conduction of an adaptive process analysis based on the determined parameters in order to obtain parameter-specific, relevant characteristics; evaluation of the parameter-specific, relevant characteristics within the framework of a logical decision-making process in order to obtain information characterizing the actual operating state; selection of known reference data of the utilized tool describing the operating state and of the to-be-machined material according to a given quality criterion; determination of an optimum operating point for the machine tool determinable by the rotational speed and percussion frequency by comparison of the information characterizing the actual operating state with the selected reference data; and regulation of the machine tool regarding the rotational speed and percussion frequency based on the determined optimum operating point.
