有する数値制御装置。[Claims for Utility Model Registration] A numerical control device having a function of reading and interpreting an NC machining program block by block and drawing a tool path locus that is a movement locus of a tool, which moves the interpreted NC machining program. A machining process discriminating means that determines whether a tool diameter correction function is valid or invalid in a command, and when it is valid, it is a finishing machining process, and when it is invalid, it is a rough machining process, and when it is determined that it is a rough machining process. By filling in the tool center path, which is the same as the tool movement path of the NC machining program, by the tool diameter dimension of the tool used in this rough machining process centered on this path, the workpiece can be machined as the tool moves. A fill drawing position calculation unit that calculates the fill drawing position for drawing the object deleted part, and a fill drawing position calculation unit that calculates the fill drawing position for drawing the object deleted part, and a tool center path that has undergone tool diameter correction processing on the tool center path of the NC machining program when it is determined that it is a finish machining process. a line drawing position calculation unit that calculates a tool path trajectory of a cutting point that is moved by a tool radius value used in this finishing process in the normal direction to the machined surface of the workpiece; the filling drawing position calculation unit and the line drawing position calculation unit; 1. A numerical control device having a tool path trajectory drawing function, comprising: a drawing function control means for drawing on a display means of the numerical control device based on a calculation result with a position calculation section.
