Numerical control device
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.
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.
2. The numerical control device according to claim 1 , wherein
the processor makes the determination by machine learning.
