Appearance characteristics of CNC machining mainly include the following aspects:
Surface finish: During CNC machining, the trajectory of the cutting tool will form the geometric appearance of the workpiece surface. For a high-finish surface, the ratio of wave height to light wavelength generally exceeds 1:50.
Surface wavelength: This is the deviation between the external geometric appearance and the external finish, which is caused by the offset vibration of the cutting tool.
Surface texture: The surface of the workpiece shows uneven grooves, which is mainly caused by the instability of the spindle movement and the tool path during CNC machining.
Surface scars: The loss of material at certain positions on the surface of the workpiece, commonly seen in burrs, cracks and scratches.
