Investigation the Milling Strategies Effects on Machining of Convex Surfaces made of Glass/Epoxy Composite

Abstract

In this study the effects of machining parameters such as shearing speed, feed rate, tool diameter and machining depth on different milling strategies i.e. 3D offset, spiral, raster and radial to produce the convex surface made of epoxy/glass composites is investigated. The effects of mentioned strategies on output parameters such as surface roughness and milling removal rate is also studied. The results show that the output of radial strategy has the minimum roughness with the highest surface quality. The raster strategy gives the maximum roughness with the lowest surface quality. Also it can be seen that in 3D offset strategy, the removal rate is maximum and subsequently the time of machining is minimum. In addition the optimized values of machining parameters to achieve the best conditions for surface smoothness and removal rate is obtained. The results of this work can be used in research and development units of industries for operational purposes.<br />
