What is CNC turning?

CNC turning is an automated machining process designed to remove layers of material from a workpiece's surface to achieve the desired shape. On a CNC lathe, the workpiece rotates while the cutting tool (turning tool) moves parallel, perpendicular, or a combination of the two relative to the axis of rotation. This process can produce cylindrical, conical, or spherical parts. CNC turning is a vital machining technology that is revolutionizing a wide range of industries.

Types of CNC Turning

CNC turning can be divided into several basic types based on the direction of tool movement and the process used:

Longitudinal turning: The turning tool moves parallel to the workpiece's axis of rotation. Turning typically requires two tool passes—the first for roughing and the second for finishing or precision turning. It is used to machine long, slender parts such as shafts, axles, or sleeves.

Transverse turning: The tool moves perpendicular to the workpiece's axis of rotation. It is used to machine end faces, such as the base of a cylinder.

Profiling turning: The turning tool moves along a template, replicating its shape. It is used to machine parts with non-standard shapes. Contour turning: The tool has a specially shaped cutting edge that imparts the desired contour to the workpiece. It is used to machine short, rotating solids.

CNC Turning Parameters

Selecting the appropriate machining parameters is crucial in CNC turning, such as:

Cutting speed: The speed at which the tool cuts the material. This parameter depends on the type of material being machined, the type of tool, and the surface finish required.

Feed rate: The speed at which the tool moves relative to the workpiece. This parameter affects chip thickness, surface quality, and machining efficiency.

Depth of cut: The thickness of the material removed in a single pass. This parameter affects cutting forces, machining temperature, and machining efficiency.

Tool type: Selecting the appropriate turning tool depends on the type of material being machined, the geometry of the machined surface, and the desired machining quality.

Cooling and lubrication: Cooling and lubrication are crucial to maintaining the correct tool and workpiece temperature during turning, as well as reducing friction and tool wear.

Selecting the appropriate turning parameters impacts machining quality, tool life, and machining efficiency.
