Dalian CNC machining refers to the machining process in which the control system issues instructions to make the cutting tool perform various movements that meet the requirements, and represents the technical and processing requirements such as the shape and size of the workpiece in the form of numbers and letters. It generally refers to the process of machining parts on CNC machine tools.

Numerical control machine tool is a type of machine tool controlled by a computer. The computer used to control the machine tool, whether it is a dedicated computer or a general-purpose computer, is collectively referred to as a numerical control system. The motion and auxiliary actions of CNC machine tools are controlled by instructions issued by the CNC system. The instructions of the numerical control system are compiled by programmers based on the material of the workpiece, processing requirements, characteristics of the machine tool, and the instruction format (numerical control language or symbols) specified by the system. The numerical control system sends operation or termination information to the servo device and other functional components based on program instructions to control various movements of the machine tool. When the machining program of the part is completed, the machine tool will automatically stop. Any CNC machine tool cannot operate without inputting program instructions into its CNC system. The controlled actions of a machine tool generally include the starting and stopping of the machine tool; The start stop, rotation direction, and speed change of the spindle; The direction, speed, and method of feed motion; Selection of cutting tools, compensation for length and radius; Tool replacement, opening and closing of coolant, etc.
