Abstract:

By analysing the change of the anodic surface topography in Electrochemical Abrasive Lapping (ECAL), the influence of the lapping action and the electrochemical action on the anodic smoothening velocity is studied. In electrochemical finishing, the micro-peaks on the anodic surface could be smoothened quickly by electrochemical action and the surface topography presents the profile wave, but in ECAL, the profile wave after electrochemical action could be divided into micro-peaks renewedly by lapping action and the alternation of electrochemical action and lapping action makes the surface topography before electrochemical action present profile micro-peaks, which will increase the anodic smoothening velocity. The influence of machining parameters, such as abrasive grain sizes, tool’s pressure, abrasive content, frictional velocity and current density etc, on the anodic smoothening velocity is discussed in detailed.
