The present method relates to finish boring of prebored bores in a work piece such that an operative fit with a counterpart or further work piece is achieved. The finishing of the bore may be accomplished independently of the instantaneous temperature of the work piece and of the counterpart by operating a tool carriage, for example, on a lathe, with a stepping motor controlled by a correction value computer which generates a control signal in response to a temperature difference between the work piece temperature and a reference temperature. The reference temperature may be that of the further work piece.
