What does 'meters per minute' measure in machining?

• A. The quantity of metal removed
• B. The speed at which the cutting surface travels
• C. The force applied during cutting
• D. The cooling rate of the material

Answer: (B)

'Meters per minute' is a unit of measurement that indicates the speed at which the cutting tool moves across the material being machined. In machining, this speed is crucial because it directly affects various aspects of the cutting process, including the efficiency of material removal, tool wear, and surface finish quality. When the cutting surface travels at the appropriate speed, it optimizes the cutting conditions, leading to more effective chip removal and reduced heat generation. This balance helps maintain the integrity of both the cutting tool and the workpiece, promoting longer tool life and better overall machining performance. Understanding the significance of the speed at which the cutting surface travels is fundamental for machinists and engineers to ensure that the machining processes are executed efficiently and effectively.
