Abstract—Milling printed circuit board (PCB) is a quite essential technology of removing areas of copper from a sheet material. The PVD hard coatings are expected to improve milling tools for PCB industry. In this study, the cutting performance of the CrAlSiN and diamond like carbon (DLC) double-layered coating deposited on the micro router was compared by machining the PCB. CrAlSiN coated tool as reference, two other coating systems including CrAlSiN and DLC double layers were deposited by cathodic arc evaporation (CAE) technology. Two different DLC layers were designed with Cr/C and CrN/C multilayer structure. The results shows that both double layered coated tools present the better hardness and cutting performance as compared to the single CrAlSiN coating. The highest improvement of the CrAlSiN + CrN/C double layered coating is nearly triple times higher than that of tool coated with single CrAlSiN layer.
Index Terms—Cathodic arc evaporation, CrAlSiN coating, diamond like carbon, wear.
