CNC machining is a manufacturing process that uses software code to control machine tool operations, transforming raw materials into parts. Engineers create a three-dimensional model of the part, defining its geometric features and dimensions. After analysis,they generate code by setting tool paths, cutting parameters, and processes. During the machining phase, the operator loads the material onto the machine tool's worktable and installs the cutting tools. Once the program is started, the machine tool runs automatically. The spindle drives the cutting tool to rotate at high speed, while the motor drives the tool and worktable to perform cutting, drilling, milling, and other operations along the coordinate axes, revealing the part's shape. After machining, the part undergoes deburring, polishing, or surface treatment processes, and is inspected using measuring equipment to ensure its performance meets specifications.
