Heavy/ light cuts will use lower cutting speeds. Which type of cuts uses the lower speeds?

• A. Heavy
• B. Light
• C. Both
• D. None

Answer: (B)

The main idea is that cutting speed is chosen to control heat, tool wear, and the stability of the cutting action as material is removed. Light cuts remove only a small amount of material and engage the tool shallowly, so running at a lower speed helps keep heat under control, ensures smoother chip formation, and reduces the risk of rubbing or chatter. This preserves surface finish and tool life for the light-pass operation. In this context, light cuts are the ones associated with the lower speeds.
