In recent years, advanced materials with unique metallurgical properties such as super alloys, composites and ceramics have been developed to meet the demands of extreme applications. While these materials are harder, tougher, less heat sensitive and more resistant to corrosion and fatigue, they are also difficult to machine. Advanced materials are being widely used these days not only in the a...

Article history: Received: 27.6.2013. Received in revised form: 14.11.2013. Accepted: 19.11.2013. Aluminum based Metal Matrix Composites (AlMMC) have been found in different industrial applications due to their excellent properties compared to conventional materials. Machining of these composites is difficult due to their hard particle reinforcements. The wider usage of these composites is limi...

Correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. In electrical discharge machining (EDM), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

This paper proposes a hybrid WAAM (wire arc additive manufacturing) and milling process (HWMP), and highlights its application in the fabrication of stiffened panels that have wide applications in aviation, aerospace, and automotive industries, etc. due to their light weight and strong load-bearing capability. In contrast to existing joining or machining methods, HWMP only deposits stiffeners l...

This paper will provide a method to decompose forging dies for machining planning in the case of high speed machining finishing operations. This method lies on a machining feature approach model presented in the following paper. The two main decomposition phases, called Basic Machining Features Extraction and Process Planning Generation, are presented. These two decomposition phases integrates ...

Advanced ceramic materials are gradually becoming very important for their superior properties such as high hardness, wear resistance, chemical resistance, and high strength to weight ratio. But machining of advanced ceramic like Al2O3-ceramics is very difficult by any well known and common machining processes. Normally, cleavages and triangular fractures generate when machining of these materi...

Unconventional machining processes (communally named advanced or modern machining processes) are widely used by manufacturing industries. These advanced machining processes allow producing complex profiles and high quality-products. However, several process parameters should be optimized to achieve this end. In this paper, the optimization of process parameters of two conventional and four adva...
