The CNC milling process is a digital manufacturing process that is implemented by computer numerically controlled (CNC) machines. This process is used to produce parts with complex shapes, and the manufacturing process involves multiple steps. The following are the detailed steps of the general CNC milling process:Design: First, you need to design a CAD model of the parts you want to produce. A CAD model is a three-dimensional image created using computer-aided design software that can describe the shape, size, and features of a part.Programming: Next, you need to convert the CAD model into G-code, which is a type of computer instruction that controls the movement and operation of the CNC machine. G Code can be written manually or generated automatically using CAM software.Prepare the machine: Before you start machining, you need to check and prepare the CNC machine. This includes checking the machine's coordinate system, setting tools and cutters, and setting parameters such as the machine's speed and feed speed.Processing: After the machine is ready, the processing can begin. The machining process usually consists of multiple steps, such as roughing, finishing and drilling. At each step, the CNC machine moves tools and workpieces according to instructions in the G code to achieve the desired cutting operation.Inspection: After processing, the parts need to be inspected to ensure that they meet the design requirements and specifications. Inspection can be carried out by using measuring instruments, templates and other testing tools.Polishing and surface treatment: Parts can be polished and surface treated if needed to improve their surface finish and corrosion resistance. This can be done through the use of abrasives, chemicals and other tools.In short, the CNC milling process is a high-precision, high-efficiency manufacturing process for the production of parts with complex shapes. Through the control of CAD model and G code, the precise control of machine motion can be realized, so as to achieve high-precision parts processing.
