[0002] Full-line machining refers to the process of machining the entire contour of the workpiece. In this machining process, the entire contour of the workpiece needs to be machined, not just a portion. Full-line machining is usually used in the field of workpiece machining that requires high precision and complex shapes, such as mold manufacturing, aerospace parts machining, etc. Full-line machining usually uses CNC machining technology, and the CNC machine tool processes the overall contour of the workpiece according to the pre-set machining path and parameters. This machining method can ensure the accuracy and consistency of the overall shape and size of the workpiece, while improving production efficiency and machining quality.
