This work aims to show that predictive performance is a realistic goal for a wide variety of ECM configurations. The introductory review illustrates the interdisciplinary nature of the process and includes a few ideas which might be pursued by other researchers. A theoretical examination of rotating disc tooling is extended to incorporate the additional mechanical action expected in EC grinding and is shown to agree closely with experimental observations. Subsequently, a dimensional study of EC drilling provides the foundation for regression analysis of a large number of overcut results to reveal a high order of correlation; also an appropriate differential equation is shown to have a rigorous solution. Equilibrium problems associated with face-turning are then examined followed by a theoretical and practical investigation of cylindrical turning using both flat and form tools. The penultimate chapter compares voltage and current control and deals with gap variation when using alternating current or tool vibration. EC sinking is also studied and includes an estimation of penetration requirements for stable operation. To complete the-work, previous conductivity research is re-examined and realises close experimental agreement.
