The three elements of CNC lathe cutting are speed, feed and cutting depth. These three factors are called cutting parameters, and they jointly affect the cutting effect and processing quality during CNC lathe processing. Here is a detailed explanation of these three elements:

1. Cutting speed:

CNC lathe cutting speed is the distance that the cutting edge on the tool moves along the workpiece surface per unit time.

The choice of cutting speed affects the relative movement speed of the tool and workpiece during the cutting process. Appropriate cutting speed helps to obtain ideal cutting results, but also affects the wear resistance of the tool.

2. Feed:

CNC lathe feed is the distance the tool moves along the workpiece surface per unit time, perpendicular to the direction of the cutting edge.

The feed determines how fast the cutting edge moves relative to the workpiece. Proper feed helps control tool load during cutting and affects the finish of the machined surface.

3. Cutting depth:

The cutting depth of a CNC lathe is the distance the tool moves in the vertical direction along the workpiece surface in each cut.

Depth of cut determines the thickness of workpiece material removed by the tool in each cut. Proper depth of cut helps balance machining efficiency and tool life.

There are complex interrelationships between these three elements, and reasonable selection and adjustment of them can achieve more efficient CNC lathe processing while ensuring processing quality. In practical applications, operators need to optimize these cutting parameters based on specific workpiece materials, tool types and machining requirements.
