“…Texture engraving on the tool faces i.e. flank face and rake face is derived from conventional engineering of mechanical components such as oil groves in piston, coatings in bearings, and micro channels in exchangers etc [13]. These surface modifications are done to reduce friction and heat, and thereby to increase the life of the component.…”

In this research, an investigation on machinability of nickel-based superalloy (Inconel 600) under the influence of textured tungsten carbide cutting tools is conducted. Two main machinability indicators, namely, wear and life, have been investigated. Three types of micro-texture patterns i.e. dimples, lines and splines are laser engraved on the flank face of the cutting tool. Experiments are done with different cutting velocities, feed rate and depth of cut considering the texture pattern one among the input parameters. Firstly, while machining Inconel 600 with plain (non-textured) tungsten carbide cutting tool, it is investigated that at low velocity, the cutting nose caused damage due to abrasion and friction between the tool-chip interface. Severity in tool edge has increased along with adhesive wear and builtup edge at the cutting radius with increase in velocity. Thereafter, using textured on the tools, it is observed that the cutting tool wear resistance has tremendously increased with different textured patterns due to significant reduction in friction and heat. At low velocity (50 m min −1 ) the tool wear measured is in the range of 100-150 μm and maximum of 394 μm at high cutting velocity of 150 m min −1 . The tool life was calculated using Taylor's equation based on Gaussian method. Tool lives for dimple and line textures are found superior. It is concluded that textured tools have potential to machine hard materials like Inconel superalloys with longer tool life.

“…They expounded the possibility and effectiveness of applying micro/nano surface textures on tool surfaces. Overall, it has been revealed that proper surface textured tools have advantages in reducing cutting force [6,8], suppressing contact length [9], anti-adhesion [10], and better machining quality [11] and wear resistance [12]. For instance, Xie et al [13] found a 32.7% reduction in cutting forces in machining titanium alloy for micro-groove textured (MGT) tools.…”

In recent years, surface texturing in micro-scale has been attempted on the surface of cutting tools for multiple purposes, e.g., cutting force reduction, prolonging life-span, anti-adhesion, etc. With respect to machinability and performance, micro-groove texture (MGT) has dominated in this field compared to other textured patterns. In this study, a novel volcano-like texture (VLT) was fabricated on the rake face of cemented carbide inserts (WC-Co, YG6) by fiber laser. The following cutting experiment tested the flat, MGT and VLT tools in turning aluminum alloy 6061. The effects of coolant and cutting conditions were investigated. In addition, a validated FEM model was employed to explore the distribution of stress and temperature fields in the tool-chip interface. The initial forming process of adhesion layer on rake face was investigated as well. The results indicated that lower cutting force and less adhesion can be achieved by small scale VLT. This study not only introduced VLT on cutting tools but also revealed its comprehensive performance.

“…Obikawa et al [7] experimentally investigate the effects of the micro-texture on the coated tool face in machining aluminum alloy A6061-T6 and found that the parallel type and square-dot type of micro-textures could improve the lubrication conditions effectively and consequently lower the cutting forces and energy consumption. Chang et al [8] experimentally investigated the effects of three different microstructure patterns (some microscale grooves in the directions of horizontal, perpendicular, and sloping at 45 • to the cutting edge) in reduction of tool wear in micromilling of NAK80. The experiments showed that the tool with perpendicular microstructures generated lowest cutting forces and possesses the best tool flank wear resistance performance when compared with other patterns.…”
