Abstract
A numerical control apparatus includes: a curvature radius calculating portion which calculates a first radius rwhich is a radius of a passage arc C passing through three points of a start point P, an object point P, and an end point Pas a curvature radius R at the object point P; a point sequence evaluating portion which calculates a chord error E to the passage arc C and compares the calculated chord error E and a previously defined permissible error; and a curvature radius correcting portion which calculates a second radius which is a radius of an arc in which a chord error with a front line segment and a rear line segment is the permissible error or less when the calculated chord error E exceeds the permissible error and corrects a curvature radius at the object point Pto the second radius.
