What does lathe mean?
A lathe is a machine used to shape wood, metal, plastics, and other materials. Its central working principle is rotation: the workpiece turns around an axis while a cutting tool is brought against it, removing material and producing forms such as cylinders, bowls, rods, and curved components. A person operating the machine is commonly called a lathe operator, and the broader process is known as lathe turning. The verb “lathe” refers specifically to shaping a material on such a machine, although it can sometimes be used more broadly for machining work. The word is well established in woodworking, metalworking, engineering, and craft traditions. Although modern lathes may use computer-controlled systems, the basic concept remains recognizable: a stationary tool works against a rotating piece to produce a precise shape. The term is useful when precision, symmetry, and rotation are central to the manufacturing process.
A machine that rotates a workpiece around an axis while a cutting tool shapes its surface.
"The metalworker adjusted the lathe before beginning the new component."
The machine may be used on wood, metal, plastics, and other workable materials.
To shape or turn a material on a lathe.
"He lathed the aluminum rod into a set of identical parts."
Chiefly used in woodworking, metalworking, manufacturing, and craft contexts.
The plural refers to multiple machines of this type.
"The factory has several lathes for producing precision parts."
Before computer-controlled machines, a lathe transformed a spinning workpiece with nothing more precise than a skilled operator's hands.

Where does lathe come from?
The word ultimately derives from Old English lǣþ, meaning a narrow strip or board of wood, a sense preserved in the related word “lath.” The name was applied to the machine during the period when woodworking machinery was developing, and the current machine sense dates from the early modern period. The verb “to lathe,” meaning to shape on a lathe, developed from the established name of the tool.
How lathe is actually used
The noun is standard in British and American English. As a verb, it is chiefly used in workshop, manufacturing, and craft contexts and is more specific than the general verbs “shape” and “turn.”
Easily confused with lathe
A lathe is a machine used for shaping material, whereas a lath is a narrow strip of wood.
