Applying experimental micro-tool wear measurement techniques …
Existing literature has investigated primarily straight slots or shoulder cuts in milling, 6–13 due to the described difficulties in measuring micro-tool wear. While this has been important for fundamental investigations, there is a need to increase the technology readiness level of existing wear studies so that the results can be applied ...

A review of modern advancements in micro drilling techniques
As mentioned in Table 3, time taken by EDM for drilling a micro hole of 500 μm in a 2.2 mm thick Inconel plate, is much higher (15 m) compared to twist (8 s) and laser (<1 s) [198]. During the EDM process, the electrodes wear rapidly due to elevated temperature in the working area and this increase the production cost.
