A theoretical and computational investigation into the electrochemical machining (ECM) process for the case of a moving stepped tool eroding an initially flat surface is presented. Five parametric variations of the basic geometry of the stepped tool machining process are possible, depending on the relative distance between the moving tool and eroded work. For each of the five cases, and based on one-dimensional theory, formulae have been developed to predict the minimum depth of working material that must initially be provided to enable a particular step size to be machined to a specified tolerance. The computer simulation of the ECM process which has been developed is based on the finite element method (FEM). The geometry of tool, electrolyte and work is simulated by means of a two-dimensional mesh of square elements. A system of macros has been developed which interact internally with an FE package to move component boundaries systematically to simulate both tool movement and surface erosion. Such boundary movements are accomplished automatically and continuously without user intervention during a simulation run. The algorithms employed to achieve characteristically different erosion rates are described. Results both from one-dimensional ECM theory and from the computer simulations of the characteristic cases are presented. Comparisons show that there is good agreement between computer predictions and theory. The differential erosion process is fundamental to all ECM processes. Complex shapes evolve because of spatial differences in erosion rates. Thus the one-dimensional results presented here for the formation of a step should provide a basis for comparisons between spatially separated regions of one-dimensional differential erosion on bodies of arbitrary shape.

Set Up

Electrochemical micro-machining (EMM) appears to be very promising as a future micro-machining technique, since in many areas of applications, it offers many advantages, which include excellent machining precision and control, high machining rate, perfect surface quality and a wide range of materials that can be machined, regardless of their strength and toughness. At present, electrochemical micro-machining has been applied in the production of some metal workpieces, such as micro-holes, micro-slots and complex 3D surfaces. In this paper, A new electrochemical micro-machining set-up for machining metal micro-holes has been developed. Double level mechanical structure has been applied as the main structure style, which has the advantage of excellent structure rigidity, compact framework dimension as well as perfect maneuverability and maintainability. The control system based on PLC control method has also employed to realize different motion styles for rotating axis, such as uniform velocity rectilinear motion, varying velocity rectilinear motion and cycle rectilinear motion and so on. In order to verify the reliability of this EMM set-up, some test works including static measurement, assembling interferences checking and kinematics simulation have been done. The simulation results demonstrate that the developed EMM set-up for manufacturing metal micro-holes is qualified and can satisfy the technical requirements of electrochemical micro-machining process.

Optimization Efficiency

The simulation and optimization of electrochemical machining is an important means to improve processing quality. However, the fragmented nature of geometric modeling and numerical analysis model, restricts the application proportion. Aiming at this problem, it is refined that the scientific problem of coordination modeling between CAD and CAE based isogeometric method. In this paper, the unified model is established based NURBS basis functions to solve the problems that the geometric parameterization and the infliction of boundary conditions. And the optimization efficiency is promoted by improved optimization model using the convex hull characteristic of NURBS basis function. At last, a confluent design method is realized for the blade electrochemical machining process.
