<p>A method of preparing NC data for coarse machining, wherein a path (QLi) for coarse machining is produced using points on an i-th point train path (PLi) among a plurality of point train paths that are repetitively digitized at predetermined intervals along a predetermined direction, and the next path for coarse machining is prepared and is produced using a projected point train path (PLk') closest to the i-th projected point train path (PLi') among the projected point train paths that are distant by more than a tool radius (Tr) on an XY projected plane.</p> |
