Which control is used to feed the turning tool along the axis of the workpiece during turning operations?

• A. Carriage
• B. Tailstock
• C. Crossfeed
• D. Apron

Answer: (A)

Moving the tool along the axis of the workpiece is done by the carriage. The tool is mounted in the tool post on the carriage, and engaging the longitudinal (axial) feed moves the entire carriage along the ways, advancing the tool into the spinning stock to produce a turning cut. The crossfeed, by contrast, moves the tool across the diameter (radially) and changes the depth of cut, not the along-axis position. The tailstock provides support rather than feeding the tool, and while the apron houses the feed gears and controls, the actual axial movement comes from the carriage itself.
