• (A motor-driven lathe for metal.)

Advanced Usage

• "to operate a power-lathe": to control and use this machine for turning materials.

• "power-lathe cutting speed": the rotational speed of the workpiece, measured in revolutions per minute (RPM), which is adjusted based on material and tool type.

Additional Notes

• The hyphen in "power-lathe" indicates that it is a compound word combining "power" (mechanical energy) and "lathe" (a shaping machine). The hyphen may be omitted in informal writing, but it is standard in technical contexts to clarify the meaning.
