Abstract: A workpiece machining device includes a positional deviation correction unit configured to correct a positional deviation of a radius end mill by detecting a positional deviation between a real contour line and an ideal contour line of the radius end mill. The positional deviation correction unit calculates a first correction value configured to make a center of a first arc section formed into an arc shape at a corner portion of the ideal contour line and a center of a second arc section formed into an arc shape at a corner portion of the real contour line to be identical to each other in a plane perpendicular to the rotational axis, and corrects a machining point by the radius end mill using the first correction value.
