NUMERICAL CONTROL DEVICE

摘要

Provided is a numerical control device that displays process shape diagrams (141a, 144a) obtained by analyzing a machining program having one or more unit machining programs and executing the unit machining programs. Provided are the following: a machining program analysis unit that analyzes unit machining programs in a machining program and obtains process shape information having parameters that include tool information for obtaining the unit machining program process-shape diagrams (141a, 144a); a process shape diagram creation unit that obtains process shape data corresponding to the tool information in the process shape information, and creates process shape diagrams in which the process shape data is changed on the basis of the parameters in the process shape information; and a display processing unit that displays on a display unit the machining program and the process shape diagrams (141a, 144a). The display processing unit displays the process shape diagrams (141a, 144a) in accordance with the display positions of the unit machining programs of the machining program displayed on the display unit.
