“…Recent studies show that these coatings are even better, in terms of tool life, to the multilayered coatings, as a higher number of interfaces between coating layers, confers excellent mechanical properties to the coated tool. Furthermore, these coatings have increased crack propagation, due to the high number of layers [61].…”

“…A recent tend when it comes to novel coatings is the development of nano composite coatings, evidenced by the number of studies done on this subject recently. As in the study performed by Vereschaka et al[61], a comparison of tool life is made amongst uncoated carbide inserts, commercial TiN and ZrN coatings and multilayer nanostructured Ti-TiN-(Ti,Cr,Al)N and Zr-ZrN-(Zr,Al,Si)N Maximum tool-life, displaying the obtained error for the different coatings in the machining of the Nickel alloy (graphic made based on information from[60]).…”

The milling process is one of the most used processes in the manufacturing industry. Milling, as a process, as evolved, with new machines and methods being employed, in order to obtain the best results consistently. Milling tools have also seen quite an evolution, from the uncoated high-speed steel tool, to the now vastly used, coated tools. Information on the use of these coated tools in recent scientific researches was collected. The coatings that are currently being researched are going to be presented, highlighting some novel advances in the nanocomposite and diamond coatings area, as these coatings are seeing a growing use in the industry, with very satisfactory results, with performance and tool-life increase. Wear mechanism of various types of coatings are also a popular topic on recent research, as the cutting behavior of these coated tools provides valuable information on the tool’s-life. Furthermore, analysis of these mechanisms enables for the selection of the best coating type for the correct application. Recently, the employment of coated tools paired with sustainable lubrication methods as seen some use. As this presents the opportunity to enhance the coated tool’s and the process’s performance, obtaining better results, in terms of better tool-life and better surface finish quality, in a more sustainable fashion.

“…The tool lives of TiAlSiN coating exceeds than AlTiN coating with increment in speed from 150 to 200m min −1 [79]. The use of nanostructured coatings minimizes brittle fracture, chipping and increases the tool life [80]. The cutting speed 60 m min −1 combined with radial depth of cut 0.6 mm are suggested when f z = 0.1 mm per tooth and a p = 2 mm in milling of titanium alloy under dry conditions to improve cutting efficiency.…”

In this article, the comprehensive review on the application, and indeed, a comparative analysis on dry machining of different types of materials (Inconel, steel, aluminum, cast iron, magnesium and advanced materials) used in machining (turning, drilling and milling operations) were carried out in the light of utmost works published in the literature. The work describes the scientific findings of the past twenty years, including sustainable methods (surface texture, solid lubricants, vibration-assisted machining, laser-assisted machining), tool coatings, and geometry of tools. Vibration-assisted machining is another direction that researchers have investigated without the use of cutting coolants, where the complete disposal of coolants is not possible. Various researchers have carried out rigorous experimental work on milling, drilling, and turning operations under dry conditions to machine numerous materials. A significant proportion of experimental data about tool wear, tool wear machining, surface quality, surface integrity, etc., has been analyzed under dry conditions. However, the critical analysis of dry machining for different conventional machining operations for a variety of industrial materials is still lacking for establishing dry machining as a sustainable process for industrial applications. Thus, the critical analysis of various machining parameters and their consequences on tool wear and the surface quality of machined work was carried out in this work. Finally, scientific recommendations based on critical findings were proposed for industrial implementation of dry machining.

“…One of these coating types that deserves some attention are diamond coatings used in machining as these significantly improve the wear behavior of cutting tools [28] and there have been some recent developments, further improving wear resistance by employing multilayered structures [29]. These directly improve the wear resistance of coatings, as the structure types confer the tool with properties such as improved thermal dissipation and improve crack propagation resistance, thus improving the overall tool's life and performance [30]. Still, regarding the wear performance of coated tools, the influence of the tool's substrate plays a significant role in the performance of a cutting tool.…”

Copper-Beryllium alloys have excellent wear resistance and high mechanical properties, they also possess good electrical and thermal conductivity, making these alloys very popular in a wide variety of industries, such as aerospace, in the fabrication of tools for hazardous environments and to produce injection molds and mold inserts. However, there are some problems in the processing of these alloys, particularly when these are subject to machining processes, causing tools to deteriorate quite rapidly, due to material adhesion to the tool’s surface, caused by the material’s ductile nature. An assessment of tool-wear after machining Cu-Be alloy AMPCOLOY 83 using coated and uncoated tools was performed, offering a comparison of the machining performance and wear behavior of solid-carbide uncoated and DLC/CrN multilayered coated end-mills with the same geometry. Multiple machining tests were conducted, varying the values for feed and cutting length. In the initial tests, cutting force values were registered. The material’s surface roughness was also evaluated and the cutting tools’ edges were subsequently analyzed, identifying the main wear mechanisms and how these developed during machining. The coated tools exhibited a better performance for shorter cutting lengths, producing a lower degree of roughness on the surface on the machined material. The wear registered for these tools was less intense than that of uncoated tools, which suffered more adhesive and abrasive damage. However, it was observed that, for greater cutting lengths, the uncoated tool performed better in terms of surface roughness and sustained wear.
