CNC Milling Overview
CNC milling, or Computer Numerical Control milling, is a precise machining process utilizing computerized controls and cutting tools to shape materials. Applied in aerospace, automotive, and electronics industries, CNC milling efficiently produces intricate components.
How CNC Milling Works
Begin with a 3D CAD model as a blueprint for the CNC milling machine. Convert the model into a CNC program using CAM software, guiding the machine on tool movements. Securely clamp the material, and choose the cutting tool based on material and geometry. Calibrate the CNC machine for precision, setting zero points and measuring tool offsets. The machine follows programmed instructions, removing material layer by layer to shape it according to the CAD model. Use coolant for heat dissipation and chip removal. Conduct ongoing quality checks to ensure specified dimensions are met. Finish the process with operations like deburring.
Advantages of CNC Milling
