“…Micro turning is a mechanical micromachining technology widely used for fabricating micro valves, micro nozzles, and micro molds in several industries. 1 The stiffness of the micro components is very low, so they may be subject to permanent deformation under the action of cutting force. Therefore, the cutting force requires continuous monitoring during micro turning.…”

“…However, the cutting force is lessened by a combination of a low feed rate and a low cutting velocity. 1 Chen et al 3 successfully developed a smart turning tool for micro turning operations by applying two piezoelectric films for measurement of cutting and feed forces. However, proper calibration was needed to be performed before application.…”

Cutting force for conventional orthogonal machining can be predicted by Merchant’s Circle Diagram (MCD) considering the shearing action of chip formation. However, the effect of plowing action is significant for micro turning, which has not been considered in MCD. Therefore, a large error has been observed in the prediction of cutting force in micro turning by MCD theory. In this study, a compensated model has been developed for orthogonal micro turning based on MCD. The theory has taken shearing and plowing actions into consideration. The compensated model involved material flow stress, cutting parameters, and tool geometry, including cutting edge radius. This model has predicted tangential cutting force with an average prediction error of 3.75% for micro turning of Ti6Al4V, whereas the average prediction error was 14.9% for axial cutting force.

“…Methods such as micro-grinding, micro-milling, and micropolishing are employed to modify surface structure of the tools to achieve a well-defined cutting edge, and reduce any defects that can significantly affect performance [12,13]. Within the cutting tool industry, a variety of surface treatment methods with suitable machining parameters have been developed and implemented over an extended period of time [14][15][16][17]. The aforementioned processes can be categorised into three distinct approaches: mechanical, chemical, and electrochemical.…”

The performance and lifespan of cutting tools are significantly influenced by their surface quality. The present report highlights recent advances in enhancing the surface characteristics of tungsten carbide and high-speed steel cutting tools using a novel micro-machining technique for polishing and edge-honing. Notably, the main aim was to reduce the surface roughness while maintaining the hardness of the materials at an optimal level. By conducting a thorough analysis of surfaces obtained using different techniques, it was found that the micro-machining method effectively decreased the surface roughness of the cutting tools the most effectively out of the techniques investigated. Significantly, the surface roughness was reduced from an initial measurement of 400 nm to an impressive value of 60 nm. No significant change in hardness was observed, which guarantees the maintenance of the mechanical properties of the cutting tools. This analysis enhances the comprehension of surface enhancement methodologies for cutting tools through the presentation of these findings. The observed decrease in surface roughness, along with the consistent hardness, exhibits potential for improving tool performance. These enhancements possess the capacity to optimise manufacturing processes, increase tool reliability, and minimise waste generation.
