In which process is material held in place and spun while a tool removes material?

The process where material is held in place and spun while a tool removes material is known as turning. In turning operations, a cylindrical workpiece is rotated on a lathe, while a cutting tool is fed into the material to remove excess material, creating a desired shape and finish. This method is ideal for producing cylindrical parts and is commonly used in machining to achieve precise dimensions and surface finishes.

Turning distinguishes itself from processes like milling, where the workpiece remains stationary while the cutting tool moves, often removing material in a flat or irregular pattern. Abrading refers to using abrasive materials to wear down or polish surfaces rather than cutting away material in a defined shape. Injection molding, on the other hand, involves injecting melted material into a mold to form shapes but does not include the spinning of a workpiece for material removal.
