What is defined as the linear distance that a tool advances during one rotation of the workpiece?

The linear distance that a tool advances during one rotation of the workpiece is known as the feed per revolution. This is a key concept in machining because it helps define the relationship between the tool's movement and the workpiece's rotation.

Understanding feed per revolution is crucial for various machining operations as it directly influences the machining time, surface finish, and the amount of material removed. For instance, a higher feed per revolution typically leads to a faster machining process, but it may also compromise the surface finish and tool life if not appropriately managed.

In contrast, feed rate refers to the speed at which the tool moves through the material over time, which is often measured in units like inches per minute or millimeters per minute. Feed per tooth refers to the distance that each tooth of a multi-toothed tool moves through the material per revolution, and chip load specifically addresses the thickness of the chip removed by each cutting edge during one rotation. These concepts are related but focus on different aspects of the machining process.
