Which portion of a lathe is used to give depth to the cut?

Explanation:

A lathe is a machine tool that holds the job in between the center and base and rotates the job and rotates the job on its own axis.

A Lathe has the following parts as shown in the figure below.

Tool Post 

• The tool post holds the tool meant for the operation to be performed on the work.
• The tool post is assembled to the top slide.

Carriage

• The carriage is a moving part that slides over the guideways between the headstock and tailstock
• It slides parallel to the workpiece axis
• It consists of a saddle, apron and also carries the compound rest

Cross slide

• The cross slide is assembled to the saddle with the help of the tapered jib
• The cross-slide functions perpendicular to the lathe axis either by hand feed or automatic feed i.e. give the depth of cut to the workpiece.

Chuck

• A lathe chuck is a holding device that is used for holding the job firmly against the cutting tool.
• There are two types of chuck:
  • Four Jaw Chuck: The four-jaw chuck is also called as independent chuck since each jaw can be adjusted independently.
  • Three Jaw chuck: It is also known as three-jaw universal chuck, self-centering chuck, and concentric chuck having three jaws that work at the same time.
