Electrolyte machining accuracy improvement

Chapter 7 elaborates various important influencing factors of EMM. Influence of lEG, temperature, concentration, electrolyte flow, and tool feed rate has also been described with the help of large number of practical results. Chapter 8 concentrates on various strategies to improve machining accuracy of EMM. Hybrid EMM teclmiques which are the newer developments to improve the effectiveness of EMM have also been included. Selections of optimal combination of EMM parameters validated by test results have also been incorporated to enhance the machining efficiency and accuracy. Chapter 9 includes numerous practical and industrial applications of EMM. Various factors which restrict the wider usability of this process have been discussed. This Chapter also focuses on how to minimize these adverse factors by applying various remedial measures. 

In the ECMM, it is necessary to remove very small amounts of metal this overshadows the problem of providing a high productivity of the process, which is of great importance. In this case, the electrolytes in which the passivation of the dissolving metal is virtually absent (e.g. chloride solutions) can be used, and the methods of improving the accuracy on the basis of maintaining the WP areas, which should not have been machined, passive, are unsuitable. Application of such electrolytes is also important because for some metals, copper, for example, no sufficiently simple and convenient practical electrolyte composition, in which the condition E > Eox is fulfilled, has been found.
