A lathe is a versatile machine tool used to remove material from a rotating workpiece. Its primary functions include:

External Turning: Cutting excess material from the external diameter to create straight or tapered cylindrical shapes, grooves, shoulders, and screw threads.1
Facing: Machining flat surfaces on the ends of cylindrical parts.1
Internal Operations: Enlarging or finishing holes through boring, drilling, reaming, counterboring, countersinking, and internal threading.21

While a speed lathe relies on manual tool manipulation, an engine lathe uses a power-driven cross slide for precise movement. Specialized versions, such as the screw-cutting lathe, utilize a lead screw to synchronize tool motion with spindle rotation, ensuring highly accurate thread production. These capabilities make the lathe a fundamental tool in manufacturing, often considered the "father" of other machine tools due to its foundational role in shaping metal parts.231
