Common plastic materials used in CNC machining include acetal (POM), nylon (PA), polycarbonate (PC), acrylic (PMMA), and more.
- CNC Machining: Once the design and material selection are finalized, the CNC machine is programmed using Computer-Aided Manufacturing (CAM) software to precisely follow the 3D model’s specifications. The CNC machine operates on three or more axes (X, Y, Z, and sometimes additional rotational axes) to move the cutting tool and remove material from the plastic workpiece. The cutting tool can be a drill, mill, or lathe, depending on the complexity of the part and the required features.
- Finishing: After the CNC machining process, the plastic part may undergo additional finishing processes to achieve the desired surface finish, tolerances, and features. These finishing steps may include polishing, sanding, and surface treatments like painting or anodizing.
- Inspection: The finished plastic parts are inspected to ensure they meet the specified dimensions and quality standards. Any necessary adjustments or modifications are made to meet the design requirements.
