“…Regarding the comparison of up-milling and down-milling strategies, the average values show higher values in case of up-milling, which seems to indicate that the down-milling strategy is slightly more favorable from the point of view of torque. This difference is not statistically significant given the variance observed in the analyzed sample, so considerations on the quality of the surface and other offered for the machining of these alloys manufactured by conventional technologies could be considered in this case [25]. Figure 11 shows the torque values during the cutting test at a cutting speed equal to 50 m/min and a speed of 60 m/min.…”

In the current days, the new range of machine tools allows the production of titanium alloy parts for the aeronautical sector through additive technologies. The quality of the materials produced is being studied extensively by the research community. This new manufacturing paradigm also opens important challenges such as the definition and analysis of the optimal strategies for finishing-oriented machining in this type of part. Researchers in both materials and manufacturing processes are making numerous advances in this field. This article discusses the analysis of the production and subsequent machining in the quality of TI6Al4V produced by Wire Arc Additive Manufacturing (WAAM), more specifically Plasma Arc Welding (PAW). The promising results observed make it a viable alternative to traditional manufacturing methods.

“…Johnson and Cook [23] presented a constitutive model which describes the flow stress of materials considering the effects of strain, strain rate, and temperature, and it is very suitable to express the deformation behavior of metals under high strain rate and temperature. This model is widely used as a constitutive equation in machining simulation by many researchers [24][25][26][27][28][29][30], and is often established by the SHPB tests [31][32][33][34][35][36][37]. Wu and Zhang [24] used the Johnson-Cook (J-C) equation as the constitutive model of Ti6Al4V alloy to investigate the milling process using the finite element method.…”

As a typical high specific strength and corrosion-resistant alloy, titanium alloy Ti6Al4V is widely used in the aviation, ocean, biomedical, sport, and other fields. The heat treatment method is often used to improve the material mechanical properties. To investigate the dynamic mechanical properties of titanium alloy Ti6Al4V after heat treatment, dynamic compressive experiments under high temperature and high strain rate were carried out using split Hopkinson press bar (SHPB) equipment. The stress-strain curves of Ti6Al4V alloy under different temperatures and strain rates were obtained through SHPB compressive tests. The Johnson-Cook (J-C) constitutive equation was used for expressing the stress-strain relationship of titanium alloy under large deformation. In addition, the material constants of the J-C model were fitted based on the experimental data. An orthogonal cutting simulation was performed to investigate the cutting of Ti6Al4V alloy under two different numerical calculation methods based on the established J-C model using the finite element method (FEM). The simulation results confirm that the adiabatic mode is more suitable to analyze the cutting of Ti6Al4V alloy.

“…It was concluded that there is a significant difference between UM and DM operations in terms of the hardness of the treated surface, and that the operation DM in the final passage can be used to increase surface hardness. Wu et al [9] were engaged in experimental research and simulation process at UM and DM of titanium alloy Ti6Al4V (high strength, excellent fracture resistance, and corrosion resistance) difficult for machining. Tool material was TiAlN-coated carbide, tool diameter 10 mm.…”

Original scientific paper The paper presents the research results of the impact of variable machining parameters: feed and spindle speed on surface roughness of Aluminium alloy 6005-T6, at CNC in the up and down milling with tools of different dimensions and different materials (6 HSS, 6 VHM and 10 VHM). The properties and classification of Aluminium alloys are cited. The definition of surface roughness at end milling is given and parameters that affect it are specified. It was concluded that the feed is the parameter that has the most influence on surface roughens, while the lowest roughness is achieved by up milling. Correlation equations have provided good prediction of surface roughness in the case of machining of VHM by cutter 10. The results of the experiment will serve as an input into the model for control of input parameters of the machining process by regeneration of NC code for the purpose of quality improvement of machined surface. Keywords: aluminium alloy; cutting parameters; regenerating NC code; surface roughness; up/down milling Regeneriranje NC koda u cilju poboljšanja kvalitete površineIzvorni znanstveni članak U okviru ovog rada prikazani su rezultati ispitivanja utjecaja promjenljivih parametara obrade: koraka i broja okretaja na površinsku hrapavost legure aluminija 6005A-T6, pri CNC istosmjernoj i suprotnosmjernoj obradi glodanjem s alatima različitih dimenzija i od različitih materijala (6 HSS, 6 VHM i 10 VHM). Navedene su karakteristike i klasifikacija aluminijuskih legura. Dana je definicija hrapavosti površine kod završnog glodanja (end milling) i navedeni parametri koji na nju utječu. Zaključeno je da je korak najutjecajniji parametar na hrapavost, dok je najmanja hrapavost postignuta glodanjem (up milling). Jednadžbe korelacije dale su dobro predviđanje površinske hrapavosti u slučaju obrade VHM glodalom 10. Rezultati eksperimenta poslužit će kao ulaz u model za upravljanje ulaznim parametrima procesa obrade putem regeneriranja NC koda u cilju poboljšanja kvalitete obrađene površine.
