This article discusses the surface roughness of wood and advanced engineering materials after machining and its prediction. The topics are surface roughness of precision-machined advanced engineering materials, machining of WC and Inconel, rapidly solidified Al alloys, surface roughness of wood materials, and prediction of surface roughness. Findings include that ductile streaks on silicon and glass surfaces ground or lapped with inexpensive machines largely reduced the polishing time to obtain the required surface roughness. Abrasive jet machining could remove the patterns from recycled wafers and improve the surface roughness. The roughness of WC-Co coatings was significantly improved by using the method of fast regime fluidized bed machining. As beryllium is a toxic element, the rapidly solidified Al alloy may be a good insert material to replace BeCu. Higher bonding strengths resulted from rougher surfaces of wood samples. Wood samples had reduced bonding strengths after soaking in water. Optimum artificial neural networks (ANNs) with necessary inputs could accurately predict the roughness values. ANNs trained using particle swarm optimization and genetic algorithms could predict surface roughness better than typical ANNs. Minimum quantity lubrication is a hot research topic to minimize the amount of the fluid for cost and environmental considerations.

“…The linear micro-scale grooves of hybrid texture largely assist in guiding the cutting fluid to the high-pressure contact zone because of capillary effect and quickly diffuses to the surrounding micro-scale pits. And micro-scale pits are considered as storage pools for lubricating oil [30], which supports in controlling the temperature and this combined cooling effect results in significant reduction in adhesion and wear of the tools [19].…”

“…Rathod et al [18] developed novel square and circular microtextured cutting tools and observed a reduction in machining force, tool wear and chips morphology, and the possible physical mechanisms were that micro-textures could be oil reservoirs and helped in forming a surface oil film to provide continuous lubrication for machining. Sivaiah et al [19] applied hybrid texture (the combination of circular pits and linear grooves alternately) to the tool surface under the cutting conditions of minimum quantity lubrication (MQL), favorable machinability was found in terms of cutting forces, cutting temperature, and tool wear of the hybrid textured tool, and excellent surface quality of workpiece materials machined was observed.…”

When cutting aluminum alloy with WC/Co coated tools, severe adhesion and wear exist on the tool-chip contact interface, which are the major factors leading to failure of cutting tools. To address this problem and extend service life of cutting tools, this study introduced surface textures into coated tools, trying to integrate the anti-friction properties of micro-textures with the wear resistance properties of coatings to improve tribological characteristics of tools surface. Firstly, hybrid texture consisting of micro-scale pits and micro-scale grooves were fabricated on the rake surface close to the main cutting edge of carbide tools by picosecond laser. Subsequently, the textured tools were deposited with hard-coatings CrAlN via physical vapor deposition (PVD) technology and the hybrid textured CrAlN coated tool (MPG-T) was obtained eventually. Other texture combinations included micro-scale pits and micro-scale grooves distributed in the tool-chip contact zone. Wet cutting experiments were carried out on these prepared tools. Results showed that compared with micro-scale pitted coated tool (MP-T), micro-scale grooved (MG-T) and conventional coated tool (CCT), MPG-T tool performed better in cutting forces, friction coefficient, tool adhesion and wear on the rake face and the flank face, chip morphology. Moreover, the corresponding synergistic mechanisms of hybrid texture and coatings were proposed. It’s suggested that applying the results to actual industries can enhance the cutting performance of coated tools in machining of aluminum alloy.

“…Surface textured cutting tool helps to reduce friction coe cient through increasing lubrication capacity and decreasing tool-chip contact length. Different types of textures have been created on the cutting tool surfaces and successfully used in turning [14], milling [15], drilling [16], and thread turning [17,18] processes by researchers.…”

This paper presents the effect of surface texturing and CNT enriched nanofluid lubrication on the cutting performance of cemented carbide cutting inserts during the turning of Aluminum 7075 alloy. This alloy is widely used in various industries due to its excellent properties such as high corrosion resistance, high strength to weight ratio, and good formability. Although aluminum alloys have good cutting properties because of their low strength, they adhere between tool and chip on the rake face in machining processes, and this results in the low surface finish of machined components. To solve this problem, the use of textured tools under nanofluid lubrication is proposed in this study. Firstly, different shape of textures was fabricated on the rake face, and effective texture was determined using experimental tests. Then, turning tests were carried out using the selected textured tool under CNT enriched nanofluid lubrication to enhance the cutting performance of the machining process. Results showed that the linear microgrooves perpendicular to chip flow direction have better performance in comparison to other shapes of texture. Our findings revealed that the main cutting force, built-up edge, and surface finish were reduced up to 32%, 37%, and 19% using the selected textured tool under CNT enriched nanofluid lubrication compared to dry turning condition.
