Book excerpt: This thesis deals with an experimental investigation and modelling of the electrical discharge machining (EDM) performance on titanium alloy Ti-5Al-2.5Sn. Despite enormous applications of lightweight and high-strength titanium alloy, a key problem in machining using conventional machining processes arises. The non-conventional technique, EDM, can machine difficult-to-cut materials effectively. However, in EDM, a complete and clear theory has not yet been established. The proper selection of EDM parameters for the best process performance is still a challenge. Thus, the purpose of the present work is to develop the mathematical models to predict performance characteristics (material removal rate, tool wear rate and surface roughness) along with the optimal parametric set-up of EDM on Ti-5Al-2.5Sn titanium alloy. The peak current, pulse-on time, pulse-off time, servo-voltage, polarity (positive and negative), and electrode material (copper, copper-tungsten and graphite) are considered as process variables. The experimental work was performed based on an experiment design (central composite design). The mathematical models, using the response surface method, and the artificial neural network (ANN) model, using the multilayer perception method, were developed. Analysis of variance (ANOVA) has been performed to verify the fit and adequacy of the developed mathematical models. A confirmation test was conducted to obtain the accuracy of the developed models. In addition, the surface topography of the workpiece was analysed by scanning electron microscopy (SEM). The results evidence that the developed mathematical model can predict the performance characteristics of EDM successfully. The average errors of the mathematical model in predicting material removal rate, surface roughness and tool wear rate were 4.34%, 4.17% and 4.50% respectively. While, the average errors were 2.61%, 2.77% and 3.05% for the ANN model. Thus, the ANN model is more precise than the mathematical model. The negative graphite electrode provides the highest material removal rate. However, it maximizes the tool wear rate, and causes the poorest surface finish. The positive copper-tungsten electrode becomes the best choice in respect of all performance characteristics. It was very difficult to achieve single settings of the process parameters for all the best performance characteristics. In addition, the multiple objectives were incompatible. The surface topography for negative polarity demonstrates larger craters, wider and deeper cracks and greater amounts of globules when compared to positive polarity. The obtained results lead to desirable process output, and cost-effective machining. Therefore, it becomes a precise tool, making the EDM process cost-effective and efficient in the die, mould, tool and other industries.

This book was released on 2009 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with machining Titanium alloy workpiece using Wire-Electrical Discharge Machining (EDM). The objective of this thesis is to determine the relationship between the machining parameters which is Current Pulse Duration, Voltage Off-Time, Peak Discharge Current, and Wire speed with Surface roughness (Ra). This thesis use the response surface methodology techniques to turn out the equation the equation that use to predict the Ra. The machining of Titanium alloy workpiece was performs using the Wire- EDM SODICK AQ535L. Then the analysis was done using the MINITAB software. From the result, it is observed that the second order modal give more accurate prediction data for Ra and less percent of error compare to linear model. From the previous researchers found that machining parameters had a large effect on machining performance outputs. By doing the prediction for surface roughness in Wire-EDM for Titanium alloy it will aid people to estimate the surface roughness for their selected parameters and avoid using try and error method. By considering all of these parameters, the good machining condition can be performed. This result also can significantly reduce the cost of operation and cost of product.
