This paper describes some results of the research in optimization of PVD coated carbide tip tools insert (TiCN&TiAlN) by with and without heat treatment to reduce the wear resistance, lower surface roughness, increase material removal rate & reduce the cutting forces. The development of coatings for cutting tools is considered as a boon to the cutting tools evolution. Coatings have gone through several generations of development, due to the increasing demands of the industry, such as high-speed machining, dry machining, and machining of difficult-to-cut alloys, such as super alloys and titanium. The first coatings developed were hard coatings of TiN, TiC, TiCN or aluminum oxide, and were often used in a multiple layer; materials with these coatings outperformed uncoated high-speed steel inserts, due to their superior hardness and wear resistance. With new technologies in present manufacturing market the carbide cutting tools as became a necessary tool to produce different components in automotive.
