Surface microcosmic morphology evaluation of finished by abrasive jet with grinding wheel as restraint
<正>In the paper,the machining process validity was verified by experimental investigation.Experiments were performed with plane grinder M7120 and workpiece material 40Cr steel which was ground with the surface roughness mean values of Ra=0.6μm.The machined surface morphology was studied using Scanning Electron Microscope(SEM) and metallography microscope and microcosmic geometry parameters were measured with TALYSURF5 instrument.The experimental results show the novelty process method,not only can obviously diminish longitudinal geometry parameter values of ground surface,but also can attain isotropy surface and uniformity veins at parallel and perpendicular machining direction.Furthermore,the finished surface has little comparability compared to grinding machining surface and the process validity was verified.
