What is the CNC Lathe Machine cutting movement?


Metal cutting processing refers to in the numerical control lathe, using the relative motion of the cutting tool and workpiece,removing extra metal material to obtain required designed parts. Compared with other methods, the metal cutting processing can obtain more complex shape workpiece, small surface roughness, high dimensional accuracy and position accuracy.

This tool and relative movement of the workpiece, known as the cutting movement. Cutting movement is finished by CNC lathe,including linear movment and rotary movment. However, according to the role of cutting movement in the cutting process. Cutting movement is divided into the main movement and feed movement.


CNC Lathe Machine main movement

Directly cut off the excess metal layer on the workpiece, making it a chip, thus forming a new surface movement,namely main movement. Main movement is characterized by the highest speed, the maximum power consumption.

In the cutting process, the main movement is only one,linear movement or rotary rotary.In the turning of the outer circle, the workpiece rotation movement is the main movement.


CNC lathe feed movement

Constantly cutting the cutting layer until cutting into the whole workpiece surface, known as the feed movement.The speed of the feed movement is low and the power consumed is less.The feed movement may be continuous or intermittent, and may be in the form of a linear motion, a rotary motion, or a combination.The feed movement has one, a few or no.In the turning of the outer circle, the longitudinal straight motion of the tool is the feed movement.

The main movement and feed movement can be done separately by the workpiece or tool, or by the tool alone:

The synthetic motion is the combination of the main motion and the feed motion.
