This study reports an experimental investigation about the wear behavior of TiN and TiCN coated carbide tools during the face milling of pearlitic and ferritic ductile cast iron. Pearlitic ductile cast iron caused the highest cutting forces and flank wear in both TiN and TiCN coated tools. Due to its protective effect, the TiCN coated carbide tool outperformed the TiN coated carbide tool regarding flank wear. The main issue when face milling ferritic ductile cast iron with TiN coated tools was notching wear. The principal reason for notch wear was pointed as adhesive wear caused for the high tendency of ferrite to adhere on the tool. The results demonstrated that the TiCN coating did not showed notching wear when face milling ferritic ductile cast iron, therefore a good choice of coating material can prevent notching wear.

Coated Carbide Tools

Powder metallurgy (PM) nickel-based superalloy is regarded as one of the most important aerospace industry materials, which has been widely used in advanced turbo-engines. This work presents an orthogonal design experiments to study the cutting force and cutting temperature variations in the face milling of PM nickel-based superalloy with PVD coated carbide tools. Experimental results show that with the increase of feed rate and depth of cut, there is a growing tendency in cutting force, with the increase of cutting speed, cutting force decreases. Among the cutting parameters, feed rate has the greatest influence on cutting force, especially when cutting speed exceeds 60m/min. With the increase of all the cutting parameters, cutting temperature increases. However the cutting temperature increases slightly as the increasing of feed rate. Tool failure mechanisms in face milling of PM nickel-based superalloy are analyzed. It is shown that the breakage and spalling on the cutting edge are the most dominate failure mechanisms, which dominates the deterioration and final failure of the coated carbide tools.

Layer Coating

Face milling tests on AISI 1045 steel were performed to study the flank wear of multilayered coated carbide tools. The cutting tools were dual (TiN/TiAlN) and triple (TiN/Al2O3/TiCN) layered, coated carbide inserts processed by PVD and CVD respectively. As expected, the depth of cut (DOC) did not play an important role on the development of flank wear while the cutting speed had a significant role in the development of flank wear. Using confocal laser scanning microscopy (CLSM) and wavelet transform, the flank wear evolution was analyzed and abrasive wear was found to be a dominant tool wear mechanism. Adhesion of the work material was also observed after the carbide substrate was exposed. Edge chipping and micro-fracture were additional tool failure modes. After comparing the performance of the two inserts, we concluded that the dual layer coating was superior to the triple layer coating under various cutting conditions mainly due to the benefit coming from the coating processes themselves. It was claimed that the superior performance of the multilayer coating came from preventing the gross crack-induced removal of coating materials by propagating the fracture along the coating interfaces. However, no such observations were found in our milling experiment. Therefore, the hardness of the coating materials is the most important criteria for the development of flank wear.
