PROBLEM TO BE SOLVED: To provide a machining control device of a machine tool, which provides excellent machining accuracy and efficiency by appropriately controlling a feeding speed of a machining tool against rapid variation in machining load such as rapid variation in machining allowance in a machine tool which adjusts a relative feed speed of the machining tool to a machining object.SOLUTION: A machining load of a machining tool 10 of a machine tool 1000 is monitored by a machining load monitoring unit 1 to acquire variation in machining load of the machining tool 10 and information of a location in which the variation occurs. If the machining load is equal to or heavier than a threshold, an override determination unit 4 controls an NC device 200 to preliminarily reduce the feeding speed of the machining tool on the basis of information from a load comparison unit 3 and the information of the location so that the feeding speed of the machining tool becomes a proper speed in a machining path leading to the location. |
