What is CNC Machining?How Does CNC Machining Work?
CNC (Computer Numerical Control) machining is a subtractive manufacturing process that uses pre-programmed computer software to control precision machinery. This technology transforms raw materials—such as metals, plastics, or composites—into custom parts by removing material with cutting tools, drills, or lathes. Common CNC equipment includes 3-axis, 4-axis, and 5-axis milling machines, lathes, routers, and EDMs (Electrical Discharge Machines), offering versatility for complex geometries and high-accuracy applications.
Design & Programming: A CAD (Computer-Aided Design) model defines the part’s geometry. CAM (Computer-Aided Manufacturing) software then converts this model into machine-readable code (G-code), specifying tool paths, speeds, and cutting sequences.
Setup: The operator selects appropriate tools, secures the raw material (workpiece), and loads the program into the CNC machine.
Automated Machining: The machine executes the programmed instructions, precisely cutting, drilling, or shaping the workpiece. Depending on the machine type, either the tool, workpiece, or both move to achieve the desired dimensions.
Finishing: Post-processing steps like deburring, polishing, or coating may follow to meet surface finish requirements.
