PREFACE In the last four decades, the development in the material processing domain led to the new concept named Non-Conventional or Non-Traditional Technologies. These technologies try to solve a lot of typical problems where traditional techniques proved to be inefficient. Mainly new forming, joining, casting and machining technologies have been developed. In all the cases, simulation techniques have helped to the development of the new technologies. So, Incremental Forming-Forging, Rapid Manufacturing and Laser Cladding, Laser Based Coating, Laser Based Joining, among others, are currently applied new developed materials processing without materials removal. However, the main researches on Non-Conventional Materials Processing Technologies have been carried out in Materials Removal Processes. Nearly 70 years have already gone since in 1943 two married Russian scientists, Dr. Boris and Dr. Natalya Lazarenko, with the help of the young student B. Zolotych, published the first research paper in which a non-mechanical alternative to the controlled removal of part material was proposed. The work ‘About the inversion of metal erosion and methods to fight ravage of electric contacts’ (Moscow WEI Institute, 1943) presented the fundamentals of a method in which the thermal energy generated by a controlled electrical spark was used to effectively vaporize and melt part material. The Electrical Discharge Machining (EDM) process was born. For the first time in History it was possible to machine part material with no consideration for its mechanical properties (hardness, ductility, abrasiveness,...). Since then the proposal and growth of a new group of machining processes (the so-called Non-Traditional or Non-Conventional Machining processes) has been an answer to the extreme manufacturing requirements imposed by emerging and advanced engineering materials. The development new generations
