چکیده
Two evolving surfaces define the moving boundary value problem in electrochemical machining. On side of work piece, anodic dissolution yields evolution machined surface. A novel approach for modeling process anode has recently been proposed by [6], which is based on internal variables and effective material parameters that are inserted into balance equation electric charge. Thereby, resulting distributions current densities - driving forces accurately captured without necessity to adapt finite element mesh each time step. tool side, an efficient methodology incorporate movement cathode simulation remeshing had lacking so far. Thus, we extend [6] model also whilst using a constant (see [7]). The procedure allows consideration arbitrarily complex geometries additionally may possess differently oriented feed vectors. In this paper, new anisotropic rule mixture put forward. presented example restricted stationary cathode, but focuses detailed investigation comparison with existing rules mixture, key component equivalently applicable problems.

Quartic non-polynomial spline function approximation in off step points is developed, for the solution of fourth-order boundary value problems. Using consistency relation of such spline and suitable choice of parameter,we have obtained second, fourth and sixth orders methods. Convergence analysis of sixth order method has been given. The methods are illustrated by some examples, to verify the or...
