Abstract

This research aims to investigate the effects of speed parameters, such as workpiece rotation speed and feed rate, on the surface roughness in LS-WEDT (low speed wire electrical discharge turning) process. Then a mathematical model of surface roughness can be built to deduce the formulas predicting the surface roughness values. In addition, with designing the experiments to verify the reliability of the model at a specified WEDT process conditions, it is demonstrated that the predicted Ra values are closer to the experimental Ra values at larger pitch (above 0.05mm). At smaller pitch (below 0.05mm), the other evolutional model is built to predict the surface topography, and then calculate the surface roughness with MATLAB software. It is found that the predicted surface topography has several geometric characteristics in accordance with the experimental surface topography and the predicted Ra values are closer to the experimental Ra values. Therefore, the surface roughness and topography can be quantitatively predicted from the specified WEDT parameters.
