What machining process involves rotating a cylindrical workpiece?

The machining process that involves rotating a cylindrical workpiece is turning. In turning, the workpiece is mounted on a lathe, which spins it at high speeds while a cutting tool is applied to remove material, resulting in the desired shape and dimensions. This process is particularly effective for creating cylindrical parts, as the rotation of the workpiece facilitates the cutting action of the tool, allowing for precise control over the machining operation. The primary focus in turning is on achieving accurate diameters and finishes on cylindrical surfaces, which is not the case with other processes like milling, grinding, or drilling, where the workpiece may not be intentionally rotated in the same manner or may not involve cylindrical forms at all.
