“…The most uniform topography with the small areas with single high peaks is characteristic of materials under 50% strengthening. In comparison, significantly more surface defects are observed on the surfaces after finish turning of iron-based MMCs reinforced with graphite and hard nano-oxides [18]. Similar particularities were observed by Feldshtein et al [19].…”

High-temperature thermo-mechanical processing (HTTMP) is a combination of plastic deformation and heat treatment operations. Such action makes it possible to increase metal mechanical properties resulting from both mechanical strengthening and heat treatment. As a result, it is possible to achieve high complex of operating characteristics of different types of steel and other alloys. However, there is a lack of information on the applicability of HTTMP of powder steel. These types of steel are very effective substitutes for traditional structural steel but are characterized by poor mechanical properties. This study considers the possibility of using HTTMP for powder steel frame additionally infiltrated by bronze with MoS 2 addition to increase mechanical properties of the materials studied. Steel infiltrated, infiltrated and then hardened, infiltrated and then HTTMP treated with strain rates of 30, 50 and 70% were compared. The microstructural properties and hardness of the materials before machining were studied as well as the cutting forces and surface topography of those materials after turning with AH8015 carbide inserts. Cutting forces tests were realized with v c = 157 m/min, f = 0.25 mm/rev and a p = 0.25 mm. Surface topography tests were carried out with v c = 157 m/min, f = 0.25 mm/rev and a p = 0.25 mm. Constant cutting parameters were used to eliminate the effects of rest factors. It was found that the lowest cutting forces (F c , F p and F f ), surface roughness parameters (Sa and Sq) and small areas with single high peaks on the machined surface were obtained for infiltrated powder steel with subsequent HTTMP machining under 50% strain rate.

“…In all outputs, it was observed that the results were better in the nanoparticle-added MQL environment. Maruda et al 55 machined Ti6Al4V titanium alloy in dry and MQL environments at different cutting speeds and feed rates at a constant depth of cut in this study. The effects of these parameters on surface topography were investigated.…”

This study primarily focuses on green machining, which refers to the environmentally friendly machining of parts without compromising the environment and human health. Green machining, an innovative approach in the manufacturing industry, aims to reduce the environmental impact and promote sustainable practices throughout the machining process. Green machining involves the utilization of methods such as machining, dry machining, high-performance cutting, hybrid machining, and high-speed cutting, along with environmentally friendly lubrication practices. The objective of this research is to investigate the effects of machining Ti6Al4V alloys, a widely used lightweight metal in the aerospace industry known for its challenging machinability. The study specifically examines cutting force, surface roughness, and tool wear under various cutting parameters and tribological conditions. The use of a new lubrication/cooling method was investigated in order to minimize the effects of traditional cutting fluids used in the machining of difficult materials, which may cause environmental and human health. This way, sustainable green production compatible with the environment has been realized today, where global warming and carbon emissions are rapidly increasing. In addition, it was observed that the factor determining the cutting force was the depth of cut and the feed rate was the most significant factor affecting the surface roughness.
