2. Overview of the Working Principles of Rapid CNC Machining

 

The working principle of rapid CNC machining is primarily based on the CNC (Computer Numerical Control) system. First, a 3D model of the product is created using CAD software, which is then converted into G-code or M-code that the machine can understand. These codes describe the tool's movement trajectory, cutting speed, cutting depth, and other parameters during the machining process. Next, the code is input into the CNC system, which calculates and controls the servo drive system to drive the machine tool along the predetermined path for machining operations. Throughout the machining process, the CNC system monitors the machine's operational status in real-time and adjusts as needed to ensure machining accuracy and efficiency.
