Abstract: This article describes the validity of a compound precision finishing process that combines grinding with abrasive jet finishing for micro-removal machining. Experiments were carried out with a M7120 plane grinder and a workpiece material of 40Cr steel, which was ground to a surface roughness with a mean value of Ra = 0.6 μm. The machined surface morphology was studied using a scanning electron microscope (SEM), and a metallography microscope. Microcosmic geometry parameters were measured with a TALYSURF5 instrument. The experimental results show that this novel processing method can effectively diminish longitudinal geometry parameter values of the ground surface, moreover attain an isotropic surface and uniform veins in the parallel and perpendicular machining directions. Furthermore, the finished surface has little comparability compared with a grinding machining surface. The effectiveness of the process was verified.

Keywords: grinding wheels; precision finishing; surface morphology; integrated manufacturing; manufacturing technology; abrasive jet finishing; micromachining; steel; surface roughness; surface quality.
