Numerical control apparatus
A numerical control system includes a curved-surface state evaluating unit for forming curved-surface evaluation data of evaluation points by arranging, virtually, the tool on a given scheduled path locus, that serves as the criterion of movement of a tool, to come into contact with a processed surface of a processing object, and by setting a plurality of evaluation points to evaluate the shape of the curved surface, a command speed deciding unit for deciding a command speed appropriately by using a passing speed and other data in the evaluation data, and a tool position data forming unit for calculating quickly a succeeding tool position by utilizing the evaluation data. The operations are performed in real time.
