Optimising method for regulating the operating state of a guided machine tool comprising a rotating percussion tool during a boring process

摘要

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 said 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 said machine tool; conduction of an adaptive process analysis based on said determined parameters in order to obtain parameter-specific, relevant characteristics; evaluation of said 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 said machine tool determinable by the rotational speed and percussion frequency by comparison of said information characterizing the actual operating state with said selected reference data; and regulation of said machine tool regarding the rotational speed and percussion frequency based on the determined optimum operating point.
