Answer :
Final answer:
In a lathe, the crossfeed speed is usually half of the longitudinal feed speed.
Explanation:
In the context of a lathe, the crossfeed speed refers to the motion of the cutting tool perpendicular to the workpiece, while the longitudinal feed speed refers to the motion parallel to the workpiece. Typically, on most lathes, the crossfeed speed is about half that of the longitudinal feed speed.
