The effects of electrolyte layer thickness and swelling of electrolyte at the edges of the workpieces on the shape of the electrolytic superfinished surface was studied theoretically and experimentally. The perforated resinoid bonded wheel was taken to be a homogeneous electrolytic layer. To calculate the electric field intensity at any point on the superfinished surface in cases when there is no swelling of the electrolyte, conformal mapping is employed; and in cases when the electrolyte dose swell resistant paper method is employed. Hence the shape of finished surface was estimated on the assumption that the quantity of electrolysing at any point on the finished surface is proportional to the intensity of electric field at the same point. Eventually cases when both cutting and electrolysing effects were present were considered.
The results obtaind are as follows :
1) The degree of edge rounding was found to be approximately proportional to the thickness of the electrolyte layer in cases when there is no swelling of the electrolyte.
2) The degree of edge rounding increases by an amount equal to the amount of electrolysing on the sides in cases when there is swelling of the electrolyte.
3) The shape of the electrolytic superfinishid surface can be obtained by superimposing the electrolysing and cutting effects.
