In this paper, a new approach in predicting the hardness of Titanium Aluminum Nitrite (TiAlN) coatings using hybrid RSM-fuzzy model is implemented. TiAlN coatings are usually used in high-speed machining due to its excellent surface hardness and wear resistance. The TiAlN coatings were produced using Physical Vapor Deposition (PVD) magnetron sputtering(More)
This paper investigates the performance of brass electrode on the removal of aluminium alloys LM6 (Al-Sil2) in an electrical discharge machining (EDM) die-sinking. The machining parameters such as pulse-on time, pulse-off time and peak current were selected to find the responses on the material characteristics such as material removal rate (MRR), electrode(More)
Traditional contact lathing is greatly challenged by the rapidly being developed super hard engineering materials. Being the earliest machining process, lathing operation captures 60 % of the total machining processes in most metal cutting industries. This paper reviews the literature related to the available technological solutions for non-contact laser(More)
