Cutting speed is one of the most critical parameters in CNC machining. It refers to the relative surface speed between the cutting edge of the tool and the workpiece, usually measured in meters per minute (m/min) or feet per minute (ft/min). For CNC manufacturers, the cutting speed directly affects machining efficiency, surface finish, and tool life. Incorrect cutting speed may result in rough surfaces, excessive tool wear, or even machining failure. Understanding the definition of CNC cutting speed is essential to improve productivity and ensure machining quality.
