• state the part programming of CNC turning.
Introduction To Cnc Turning (Lathe) And Advantages

• Introduction of CNC lathe and operations:
CNC (Computer Numerical Control) lathes are advanced machine tools used for precision machining operations
in manufacturing industries. Unlike manual lathes, which require manual operation by skilled machinists, CNC
lathes are automated machines controlled by computer programs to perform various turning operations with high
accuracy and repeatability.
Here’s an introduction to CNC lathes:

1 Basic Principle:
• CNC lathes operate on the principle of rotating a workpiece while a cutting tool removes material from its
surface to create cylindrical or conical shapes.

• The cutting tool is mounted on a tool post and moves along the workpiece’s length to remove material according
to programmed instructions.

Components:
• Bed: The main structural component of the lathe, providing support for the workpiece and other machine
components.
• Headstock: Houses the spindle, which rotates the workpiece at high speeds.
• Tailstock: Supports the opposite end of the workpiece and may contain a centre for additional support.
• Carriage: Holds the cutting tool and moves along the length of the bed to perform machining operations.

• Control Panel: Contains the interface for programming and operating the CNC lathe, typically using a control
unit with a display screen and keypad.
