<P>PROBLEM TO BE SOLVED: To provide a numerical control device for correcting so that the position of a tool tip point which is a processing point is correct when a work installation error exists in a three-shaft processing machine having at least three straight shafts. <P>SOLUTION: A numerical control device controlling a three-shaft processing machine which processes a work (workpiece) mounted on a table by at least three straight shafts includes a work installation error correction part 92 which corrects an installation error when the work is installed. A translational error and a rotational error are input to the work installation error correction part 92 from a translational error and rotational error specification part 96 as correction amounts. A corrected program instruction is interpolated by an interpolation part 94, and a motor of each of the shafts 98X, 98Y and 98Z is driven and controlled by error-corrected interpolation data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
