CNC milling starts with designing the part to be produced. This is done using computer-aided design software, which generates a 3D model. The next step is programming the machine and then loading the raw material. Once everything is set up, the actual milling can begin. During this step, the cutting tool moves along the X, Y, and Z axes to sculpt the material. After milling is complete, the final step is conducting a quality control check. Depending on the application for the piece, additional finishing processes like deburring or sandblasting may be necessary.
