PROBLEM TO BE SOLVED: To provide a numerical control device capable of executing an auxiliary macro function at high speed at a higher priority.SOLUTION: A numerical control device 100 assumes processing for analyzing a macro program of an auxiliary macro function as pre-analysis processing for performing analysis processing in advance and creating execution data, and performs only execution processing of the auxiliary macro function on the basis of the created execution data in each execution period during periodic processing. Among processing necessary to execute the auxiliary macro function, only the execution processing relatively low in processing load is executed during the periodic processing. Furthermore, reference time Tb is provided as time for which a task at a high priority can be executed in each execution period in a periodic processing phase, and execution of the auxiliary macro function in the execution period is adjusted so that the auxiliary macro function can be executed within the reference time Tb, thereby making it possible to execute the auxiliary macro function at a high priority without disturbing the execution of the other processing.SELECTED DRAWING: Figure 2 |
