CNC (Computer Numerical Control) machine monitoring refers to the process of monitoring and analyzing the performance, utilization, and efficiency of CNC machines used in manufacturing processes. CNC machines are automated tools controlled by computer programs to perform precise machining operations such as milling, turning, drilling, and grinding.

CNC machine monitoring systems capture data on factors such as machine utilization, spindle speed, tool changes, cutting forces, and production output. This data helps manufacturers track machine performance, identify bottlenecks, optimize tooling and machining parameters, and improve overall productivity.
