To provide a numerical control device capable of directly determining whether or not a cutting fluid is applied to a cutting point. A numerical control device includes a determination unit configured to make, on a basis of image data acquired when a vision sensor photographs a cutting fluid jetted from an injection nozzle toward a cutting point, determination of whether or not the cutting fluid is applied to the cutting point, and an instruction unit configured to issue an instruction to a nozzle control device configured to control a position and an attitude of the injection nozzle on a basis of a result of the determination of the determination unit.

Numerical control device

Provided is a numerical controller capable of calculating an optimum feed rate in machining in which cutting is performed in a different direction from a direction of a spindle axis. The numerical controller includes a tool data storage unit for storing tool data related to a tool attached to the spindle axis, a command analyzer for reading and analyzing a command block from the machining program, and generating movement command data for relatively moving the spindle axis with respect to the workpiece and spindle axis rotation command data for rotating the spindle axis, and a cutting speed controller for calculating a recommended cutting feed rate of the spindle axis based on the tool data of the tool, and clamping a cutting feed rate of the spindle axis included in the movement command data at the recommended cutting feed rate when the cutting feed rate of the spindle axis is larger than the recommended cutting feed rate.
