Claim of US Patent No. 10,915,087

1. A numerical control device comprising:a memory that stores a program; and
a processor configured to execute the program to:
make, on a basis of image data acquired when a visual sensor photographs a cutting fluid jetted from an injection nozzle toward a cutting point, a determination of whether or not the cutting fluid is applied to the cutting point; and
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, wherein
the processor makes the determination on a basis of a shape of a path of the cutting fluid extracted from the image data by detecting the edge portions of the path by pattern matching.
