“…Among all these technologies, laser surface texturing has become a competitive technique due to its high accuracy, efficiency, attractive processing times, and eco-friendly nature [ 15 ]. Previous research reported a better cutting performance with nano-textured tools due to lower material accumulation in the structure grooves, in comparison to the micro-textured tools [ 17 , 18 , 19 ]. A promising approach for high-throughput laser texturing is the direct laser interference patterning (DLIP) technique.…”

“…Depending on the number of laser beams as well as on the used geometrical configuration, different pattern geometries can be obtained, and the repetitive distance (period) can be reduced up to half of the laser wavelength. This technique has been already used for a wide range of applications, including wettability, anti-ice properties, and tribology [ 17 , 18 , 19 , 20 ]. In the case of tribological applications, several studies have demonstrated that periodic structures are more efficient in reducing friction coefficient and wear and increasing lubricant lifetime [ 21 , 22 ].…”

In times of societal development, sustainability has become a major concern for many manufacturers in the metal industries. In this context, surface texturing of cutting tools offers a promising approach in terms of reducing energy consumption and material waste. In this work, direct laser interference patterning is utilized for producing periodic line-like structures with spatial periods of 2.0 µm and 5.5 µm on rake-flank faces of cemented tungsten carbide cutting inserts. Structure depths up to 1.75 µm are reached by controlling the applied number of laser pulses. Turning experiments under lubricated conditions carried out on Al 6061 T6 parts with textured and untreated tools are performed to determine their tribological performances. The used textured cutting tools can effectively decrease machining forces up to 17% due to the corresponding improvement in frictional behavior at the tool/chip interface. Furthermore, the laser-processed tools produce thinner chips and decrease the surface roughness by 31% of the aluminum work piece.

Previous research reported a higher cutting performance with nano-textured tools due to lower material accumulation in the structure grooves, in comparison to the micro-textured tools [14][15][16] One approach thar favors high material throughput the consequently lower costs, is direct laser interference patterning (DLIP) technique. In DLIP, two or several more laser beams are superimposed at the material surface and generate an interference pattern 13 .…”

Nowadays, improving processes sustainability has become a major topic for many manufacturers in metal processing industries. Next to the challenging rise of costs of raw material and tools, innovative and hard to process materials enter the market. Here, surface functionalization of cutting tools is devised as a convenient approach for reducing energy consumption as well as material losses. In this work, direct laser interference patterning (DLIP) is used for manufacturing periodic line-like structures with spatial periods of 5.5 µm on tungsten carbide. The texturing is applied on rake-flank faces of the cutting inserts, leading to texture depths up to 1.75 µm by controlling the amount of used laser pulses. Moreover, turning experiments under lubricated conditions carried out on Al 6061 T6 parts with structured and untreated tools are performed to investigate the tribological performance. In result, the used DLIP-functionalized cutting tools could effectively decrease machining forces up to 12 %. This is caused by the corresponding improvement in frictional and improved lubrication behavior at the tool/chip interface. Furthermore, the laser-processed tools generate thinner chips, which leads to a decrease in surface roughness by 31 % of the aluminum work piece. This work thus offers insight into the viability of improving cutting tools by laser surface micro patterning for upcoming innovative materials designed for improving tool wear resistance, energy efficiency and surface quality.
