“…This is because when high cutting speeds are reached, most of the chips move off the tool cutting edge and the heat generated by the high friction causes the chips to accumulate on the tool. Thus, it causes a decrease in surface quality [38][39][40]. According to these results, the surface quality is the best when the speed is 1000m/min.…”

“…According to these results, the surface quality is the best when the speed is 1000m/min. In the study of Morelo et al [38], It is stated that in order to obtain low surface roughness, the feed rate should be chosen low and the nose radius should be chosen relatively large. In this study, the same nose radius was selected for each tool and it was concluded that the surface roughness was reduced when a low feed rate was selected.…”

The superalloys are hard to machine materials used in critical applications such as aeronautics and aerospace sectors. One of the most important parameters of the machinability tests is the surface roughness values, which enable us to determine the specific properties of the material measured from the surface of the materials being machined. So, this study proposes to advance a depth understanding of surface roughness evolution, of Incoloy 825 material, when is submitted to machining process. The machinability of Incoloy 825 superalloys were investigated by varying different high-speed machining parameters. Three different cutting tools (I, II and III), three different speeds (500, 1000 and 2000 m/min) and three different feed rates (0.1, 0.2 and 0.4 mm/rev) were chosen as parameters. The surface quality, chip formation and tool wear outputs of the Incoloy 825 machined workpiece were analyzed and optimum machining parameters were determined. The results indicate that the key parameters impressing the surface roughness, of the Incoloy 825 superalloy, are the cutting speed and feed rate, respectively. Further, the cutting tools investigated have not had a material impact on the surface roughness. The accelerated tool wear is driven by the cutting speeds as well. An overview of the results achieved in this study indicate that the optimal surface roughness value is reached when the following parameters are imposed: tools type: II, cutting speed: 1000 m/min and feed: 0.1 mm/rev.

Resumo A avaliação do comportamento tribológico de superfícies tratadas termoquimicamente, tais como cementação e nitretação, é de suma importância para a cadeia produtiva de ferramentas, moldes e matrizes. Entretanto, o uso de ensaios tribológicos para estas superfícies deve ser bem selecionado, de modo que se evite avaliações errôneas, em particular por conta do efeito do substrato em diferentes níveis. Neste contexto, o ensaio de riscamento linear pode ser bastante adequado para distinguir os papeis da superfície e do substrato. Para tanto, este trabalho apresenta uma revisão sobre o uso deste tipo de ensaio para a avaliação tribológica em termos de desempenho de superfícies tratadas termoquimicamente. A abordagem utilizada é multiescala, considerando que tipos de resultados são obtidos a partir de cada faixa de carga utilizada e as aplicações para cada uma das mesmas.

Difficult-to-cut alloys, which include titanium, cobalt, nickel alloys, and high-strength and heat-resistant steels, can nowadays be manufactured using selective melting (SLM), and products made of such materials are widely used in aerospace, automotive, and medical applications. SLM is widely used among other methods of additive manufacturing (AM) for the production of parts with complex geometry which are difficult to produce using conventional manufacturing processes. In this review article, for the first time, a comprehensive literature review of the most important parameters which influence the SLM manufacturing process of difficult-to-cut alloys is discussed and analysed. Parameters such as composition, grain size, defects, texture, and thermo-mechanical properties and their effect on surface integrity, namely surface topography (machined surface defects, surface roughness, surface texture), microstructural alterations (plastic deformation, grain refinement, and orientation, white layer formation), and mechanical properties (work hardening layer formation and microhardness, residual stress) are discussed. As a result, this review article shows the advantages and disadvantages of using various compositions, classifications, microstructure, defects, and properties of SLM of difficult-to-cut alloys on surface integrity and outlines development prospects, challenges, and future trends.
