In an effort to make the ECM process more appealing for industrial use, through the reduction of costs associated with this implementing this method, this work introduces a simulation based on the finite-element method that allows a time-dependent analysis of the machining process. Following on from the development of an initial two-dimensional simulation, a number of different industry specific applications are presented. These include the machining of non-flat workpieces, machining using A.C. supply, and a simulation of a non-equilibrium turbine blade set-up that uses a combined tool configuration. Towards the end of this work the industrial applicability of this simulation work is progressed further into three-dimensions. For each of these industry specific adaptations, sample results are presented. In addition to these adaptations, a section of this work discusses the development of a non-ideal, time-dependent simulation of ECM. Based on the findings of experimental work using a unique ultrasound system, this involves the introduction of a parameterised overpotential model. The increased accuracy gained from introduction of this model is then assessed through comparison with experimental data.
