CNC machining refers to a process method for machining parts on CNC machine tools. The process rules of CNC machine tool machining and traditional machine tool machining are generally consistent, but there have also been significant changes.
A CNC machine tool is a 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 movement and auxiliary actions of CNC machine tools are controlled by the instructions issued by the CNC system.
CNC machining refers to the processing in which the control system issues commands to make the tool perform various movements to meet the requirements, and the shape and size of the workpiece and other technical requirements and processing technology requirements are expressed in the form of numbers and letters. It generally refers to the process of machining parts on CNC machine tools.
CNC machining is a machining method that uses digital information to control the displacement of parts and tools. It is an effective way to solve the problems of variable parts variety, small batch, complex shape and high precision, and realize efficient and automatic processing.
The controlled actions of CNC machining generally include starting and stopping the machine tool; starting and stopping the spindle; changing the direction and speed of rotation; the direction, speed and type of feed motion; selecting the tool; compensating for length and radius; replacing the tool; opening and closing the coolant, etc.
