“…Also, a correlation between the applied cutting speed and the cutting tool life was studied to reveal cutting speed influences on the machinability process. Ghani 2 International Journal of Manufacturing Engineering et al studied the machinability of Inconel 718 and Metal Matrix Composite (MMC) alloys using vertical and down milling operations [6]. Their study included the investigation of the formed wear on carbide cutting tool edges.…”

This paper presents a study of tool wear and geometry response when machinability tests were applied under milling operations on the Super Austenitic Stainless Steel alloy AL-6XN. Eight milling trials were executed under two cutting speeds, two feed rates, and two depths of cuts. Cutting edge profile measurements were performed to reveal response of cutting edge geometry to the cutting parameters and wear. A scanning electron microscope (SEM) was used to inspect the cutting edges. Results showed the presence of various types of wear such as adhesion wear and abrasion wear on the tool rake and flank faces. Adhesion wear represents the formation of the built-up edge, crater wear, and chipping, whereas abrasion wear represents flank wear. The commonly formed wear was crater wear. Therefore, the optimum tool life among the executed cutting trails was identified according to minimum length and depth of the crater wear. The profile measurements showed the formation of new geometries for the worn cutting edges due to adhesion and abrasion wear and the cutting parameters. The formation of the built-up edge was observed on the rake face of the cutting tool. The microstructure of the built-up edge was investigated using SEM. The built-up edge was found to have the austenite shear lamellar structure which is identical to the formed shear lamellae of the produced chip.

“…When the working on the titanium alloy the tool wear gradually increased after the damage of the coating surface. Various researchers suggested that use only coated insert for machining of titanium alloy [1,4]. Basically, two types of coating (CVD & PVD) used during the machining of hard materials.…”

“…At elevated temperature, a chemical reaction takes place between the tool and workpiece causes the wear in tools also chips affected the rake surface of the tools. Mainly flank wear (adhesion), notch wear and crater wear (diffusion) produce during the machining of Ti-6Al-4V ELI alloy [4,5]. Sulaiman et al [1] analysed the tool wear rate for an uncoated tool insert during high speed turning of Ti-6Al-4V ELI alloy in a dry environment.…”

Ti-6Al-4V ELI has similar properties as of Ti-6Al-4V (Grade 5) except it has higher ductility as well as improved fracture toughness. It has the ability to withstand high temperature without losing properties, highly corrosion endurance and high strength to weight ratio. So it's widely applicable in biomedical implants, aerospace industry, military application, automobile component and high pressure cryogenic vessels. During the machining of the titanium alloys, a lot of machining difficulty occurs due to its hardness, chemical reaction take place between tool and machine workpiece, high amount of heat generated at cutting zone. Cutting speed and cutting feed are predominant factors for cutting tool wear as well as the finished quality of the surface. Mainly flank wear (adhesion), notch wear and crater wear (diffusion) are identified during the machining. Cutting temperature indirectly influenced the surface quality of machined surface and tool wear. The high cutting speed with low feed rate is a most favourable combination for cutting force. For cutting insert, performance tool coating plays a significant role and coated inserts performed better than the uncoated tool at various cutting conditions. Machining under minimum quality lubrication is more favourable than flooded and dry scenario.

“…A number of studies [7][8][9][10] have shown that the chipping and breakage of the tool are the major failure modes during machining, including milling, of nickel-based superalloys using WC-Co tools. The progression of tool failure during the milling of a nickel-based superalloy (718Plus), using an ordinary milling condition, has been characterised and explained [11].…”

Understanding how feed rate (f t ) affects tool deterioration during milling of Ni-based superalloys is practically important, but this understanding is currently insufficient. In the present study using a 718Plus Ni-based alloy and cemented tungsten carbide tool inserts, milling experiments were conducted with f t = 0.10 mm/tooth under either dry or wet (with coolant) conditions. The results are compared to those based on using f t = 0.05 mm/tooth from previous studies. The milling force (F) was monitored, the cutting tool edge was examined and the flank wear (VB max ) was measured. As would be expected, an increase in f t increased F. It was found that F correlated well with VB max for the high f t (0.1 mm/tooth) experiments, as opposed to the previously observed poor F-VB max relationship for the lower f t (0.05 mm/tooth) value. This is explained, supported by detailed failure analysis of the cutting tool edges, by the deterioration mode to be dominantly edge chipping with a low occurrence of fracturing along the flank face when the high f t was used. This dominancy of the deterioration mode means that the tool edge and workpiece contact was consistent and thus resulted in a clear F-VB max relationship. A clear F-VB max relationship should then mean monitoring VB max through monitoring F is possible.
