Example Embodiment
[0015] Example 1.
[0016] Reference figure 1 : Laser processing system for composite micro-texture processing on the surface of nodular cast iron materials. It is a processing system with focusing lens, including laser [1], photoelectric shutter [2], beam expander [3], mirror [4], and computer control system [5], focusing lens [6], CCD[7], workpiece [8], translation stage [9] and fixture [10]. The computer control system [5] is connected to the laser [1], photoelectric shutter [2], CCD [7] and the displacement stage [9] through lines.
[0017] The laser processing method of composite micro-texturing on the surface of nodular cast iron material includes the following steps.
[0018] (1) Prepare the workpiece [8]. The workpiece material is QT900-5. First, sand the surface with sandpaper to make the surface free of burrs and smooth. Use acetone, ethanol, and water to clean ultrasonically for 1-3 minutes each to make the surface free of oil and particles.
[0019] (2) Use a fixture [1...
