Aiming at the problem of tool compensation in the processing of multifeature parts,the local compensation method was adopted to avoid the mutual influence of the machining accuracy of the connection features of parts when the tool was compensated.An example was given to analyze the application of this method in FANUC-0iT CNC system.The results show that the machining accuracy of the connection features of the multifeature shaft part is guaranteed and the overall machining accuracy of the parts is improved.
