WHAT IS CNC MILLING
CNC milling generally refers to the process of processing parts on a CNC milling machine. CNC milling machine is a machine tool controlled by a computer and an automated machine tool equipped with a program control system. The control system can perform logical processing on programs with control codes or other symbolic instructions, decode them, express them with coded numbers, and input them into the CNC device through the information carrier. After calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing.
The process of machining parts on a CNC milling machine is called CNC milling.
CNC milling machines have strong adaptability and flexibility and can process parts with particularly complex contour shapes or difficult-to-control dimensions, such as mold parts, shell parts, etc. It can also process parts that cannot be processed or are difficult to process with ordinary machine tools, such as complex curved parts described by mathematical models and three-dimensional space surface parts.
CNC MILLING STEPS
- Designing the Part: The first step is to design the part to be manufactured using CAD (computer-aided design) software. Designs can also be created from 3D scans of existing parts.
- Convert to CNC code: CAD software converts the design into a set of instructions called CNC code. This code contains the precise coordinates and movements that the milling machine uses to shape the part.
- Machine Setup: The operator sets up the CNC mill by loading the workpiece into the machine and securing it. The operator also loads the CNC code into the machine’s computer.
- Milling Process: After the machine is installed, the milling process begins. According to the CNC code, the machine uses a cutting tool, usually a rotating end mill, to remove material from the workpiece. The cutting tool moves along multiple axes, such as X, Y, and Z, to create the desired shape.
