“…Whereas dimples and rectangular pits do not exceed 200 μm, the majority are made to a shallower depth, less than 50 μm. State of the art research across a range of cutting tool materials and texturing methods indicates the choice of the shallow depth is to limit thermal damage to the microstructure [ 112 ] and maintain the structural integrity of the tool [ 42 ]. The width for grooves was generally smaller compared to dimples and rectangular pits.…”

“…Different locations on a tool can be laser textured: the rake face, flank face on single point cutting tools or the margin, flute, lip relief on multiple point cutting tools ( Figure 18 [ 124 , 162 ]). On single point cutting tools, the rake face is typically textured as it is the initial region of chip-tool interaction; changes to the contact length and form have a greater effect on friction, wear, adhesion, and lubrication [ 112 , 118 ]. Flank face texturing improves the overall wear resistance; textures in this region help to remove debris and prevent inclusion scrapping between the tool and chips [ 121 ].…”

Polycrystalline diamonds, polycrystalline cubic boron nitrides and tungsten carbides are considered difficult to process due to their superior mechanical (hardness, toughness) and wear properties. This paper aims to review the recent progress in the use of lasers to texture hard and ultra-hard materials to a high and reproducible quality. The effect of wavelength, beam type, pulse duration, fluence, and scanning speed is extensively reviewed, and the resulting laser mechanisms, induced damage, surface integrity, and existing challenges discussed. The cutting performance of different textures in real applications is examined, and the key influence of texture size, texture geometry, area ratio, area density, orientation, and solid lubricants is highlighted. Pulsed laser ablation (PLA) is an established method for surface texturing. Defects include melt debris, unwanted allotropic phase transitions, recast layer, porosity, and cracking, leading to non-uniform mechanical properties and surface roughness in fabricated textures. An evaluation of the main laser parameters indicates that shorter pulse durations (ns—fs), fluences greater than the ablation threshold, and optimised multi-pass scanning speeds can deliver sufficient energy to create textures to the required depth and profile with minimal defects. Surface texturing improves the tribological performance of cutting tools in dry conditions, reducing coefficient of friction (COF), cutting forces, wear, machining temperature, and adhesion. It is evident that cutting conditions (feed speed, workpiece material) have a primary role in the performance of textured tools. The identified gaps in laser surface texturing and texture performance are detailed to provide future trends and research directions in the field.

The pulse length for ultrashort pulse lasers is considered shorter than the thermal vibration period of the material lattice. The thermal diffusion depth is negligible when compared with the optical penetration depth because laser-matter interaction occurs only near the focal volume. Hence, ultrashort pulse lasers are indicated for micromachining. This study aims to evaluate straight and zig-zag texture patterns generated by ultrashort laser pulses on the rake face of uncoated cemented carbide tools during the turning of martensitic stainless steel. The tests were performed under dry and lubricated conditions. The output variables were machining force, cutting power, chip thickness ratio and aspects of workpiece quality (form tolerance and surface roughness). The textures presented micrometric dimensions with a narrow deviation. The main results showed that the straight texture pattern decreased the machining force by 17.5% when compared to the zig-zag pattern. For cutting power, the straight pattern reduced consumption by 5.8% and 6.9% in relation to the reference and zig-zag tools, respectively. Finally, under dry machining conditions, the straight tool was able to decrease the workpiece cylindricity deviation by an average of 108% and 25% compared to the reference and zig-zag tools. The results provide evidence that texturing can affect the tribological system, chip-tool interface, with a potential impact on the sustainability of the process.

Development of advanced or new cutting tool has gained attention among the research community nowadays. Due to environmental obligation, researchers are working on hybrid machining processes without cutting fluids to improve sustainability. The effect of micro-dimple-textured tool on turning of Ti-6Al-4V alloy is assessed by considering cutting force, chip morphology and chip flow angle using finite element method (FEM) in the current study. The machining simulations are performed for both flat and textured tool using DEFORM software. The simulation results show that machinability of textured tool increased (maximum reduction 16, 30 and 12% in cutting surface roughness and chip thickness, respectively) as compared to the flat tool. The simulated results are validated by performing experimental runs, and significant coherence (error % < 10) is obtained.
