The horizontal feed in a lathe is controlled by-

Explanation

Explanation: Apron mechanism It contains the mechanism for moving and controlling the carriage which is the feature of lathe that provides the method of holding and moving the tool. The main parts of apron are: Traversing hand wheel Feed lever Feed selector Lead screw engagement lever Important Points Headstock The headstock is the main body parts that are placed on the left side of the bed. The headstock supports the central spindle in the bearings and aligns it correctly. It supports the main spindle in the bearings and aligns it properly. It also houses a necessary transmission mechanism for different speeds. Accessories mounted to the headstock gear mechanism, driving pulley, spindle, etc. Tailstock The tailstock fits on the inner ways of the bed and can slide towards any position the headstock to fit the length of the workpiece. An optional taper turning attachment would be mounted to it. The carriage holds the tools and provides movement of the tool in both cross and longitudinal directions. Feed rod It is a power transmission mechanism that provides precise longitudinal movement of the carriage. For turning the operation movement of the feed, the rod is mandatory. In some lathes feed may not be available and lead screw serves the purpose of the feed rod. Mistake Points Cross slide in a lathe moves perpendicular to the axis of rotation. Apron gives horizontal feed in a lathe machine.
