After setting the depth of cut, which handwheel does a machinist use to feed a turning tool along the workpiece?

• A. Carriage
• B. Crossfeed
• C. Tailstock
• D. Compound rest

Answer: (A)

After you set the depth of cut, you feed the tool along the length of the work by moving the carriage along the ways. The carriage handwheel provides the longitudinal feed, advancing the tool along the workpiece. The crossfeed handwheel moves the tool sideways toward or away from the center (radial), which is for adjusting the cut width or performing facing, not for feeding along the length. The tailstock stays in place to support the work, and the compound rest is used for angled cuts or taper turning. So, the handwheel used to feed along the workpiece is the carriage handwheel.
