PROBLEM TO BE SOLVED: To provide a numerical controller having a function for controlling the feeding speed of the feed shaft of a machine while judging the level of actual influence of position deviation value or follow-up position error value from the command shape of a working program on working precision or quality of a surface to be worked.;SOLUTION: The numerical controller is provided with: a working program interpreting means 2' for receiving a working program 1' including moving position allowable error values(εv, εh) of vertical and horizontal feed shafts relative to a surface to be worked; an effective error value calculating means 10 for calculating and storing vertical components and horizontal components to the surface to be worked affecting working precision or the like as effective error quantity (vertical components Ev, horizontal components Eh) from a followup position error value Ed and a position deviation value Es from the working shape by a feed shaft driving means 6 when moving the feed shaft; and a feeding speed correction value calculating means 4' for calculating and storing a corrected feed speed F' for moving the feed shaft within the moving position allowable error values(εv, εh) from the effective error quantity (Ev, Eh).;COPYRIGHT: (C)2007,JPO&INPIT
