Claim Text:
1. A numerical control apparatus, comprising: a compression processing unit that performs a compression processing that replaces a continuous plurality of pre-compression command paths with one post-compression command path which is one line segment connecting both end points of the continuous plurality of pre-compression command paths; a movement-data creating unit that corrects the post-compression command path, based on path correction/operation data for the post-compression command path, to a tool movement path, and creates tool movement data used for interpolating the tool movement path; and an interpolation processing unit that creates the tool movement path based on the path correction/operation data and the post-compression command path, calculates a movement amount in the continuous plurality of pre-compression command paths, interpolates, based on the tool movement data, the tool movement path obtained by correcting a pre-compression command path of the continuous plurality of pre-compression command paths, corrects the movement amount so as to move a tool on the tool movement path obtained when the continuous plurality of pre-compression command paths are not compressed based on the tool movement data created by the movement-data creating unit, and calculates a tool position.
