In machining, what does the term "cutting speed" refer to?

The term "cutting speed" specifically refers to the speed at which the cutting tool moves relative to the workpiece being machined. This is a crucial concept in machining because it directly affects the efficiency of the cutting process, the quality of the finished surface, and the tool wear. Cutting speed is typically measured in surface feet per minute (SFPM) or meters per minute (MPM) and is a vital parameter that machinists adjust to optimize their operations based on factors like the material being cut, the type of cutting tool used, and the desired finish.

Understanding cutting speed allows machinists to determine appropriate feed rates and depths of cut, leading to safer and more effective machining practices. By optimizing cutting speed, machinists can improve productivity and reduce the likelihood of damaging both tools and workpieces.
