S. No | Authors and year | Material | Machining method | Outcomes |
|---|---|---|---|---|
1 | Takale, A. M., & Chougule, N. K. (2019)5 | Ti49.4Ni50.6 | Wire electro discharge machining | Optimized trail run produced fewer micro cracks, low residual stress and less carbon contains on the machines surface |
2 | Geier, N., Patra, K., Anand, R. S., Ashworth, S., Balázs, B. Z., Lukács, T., & Davim, J. P. (2023)1 | Glass and carbon fibre reinforced polymer composites | Mechanical micro-drilling | Delamination resulting from micro-drilling is milder compared to that from larger-scale drilling. Geometrical defects are caused by micro-drilling, such as delamination, burrs, and fiber pull-outs, among others. |
3 | Agrawal, V., Gajrani, K. K., Mote, R. G., Barshilia, H. C., & Joshi, S. S. (2022)3 | Inconel 718 | Mechanical micro-drilling | A theoretical framework is developed to forecast tool wear during drilling over time and to assess the longevity of drills coated with anti-abrasion, TiAlSiN, and TiAlN materials. These coatings extended the lifespan of the drills, with the wear rate being most pronounced at the drill’s corner. |
4 | Soni, H., & MR, R. (2018)9 | Ti50Ni45Co5 | Wire Electro Discharge Machining | The optimum setting through the PCA and GRA gave the settings for higher MRR and lower SR. |
5 | Imran, M., Mativenga, P. T., Gholinia, A., & Withers, P. J. (2015)28 | Inconel 718 alloy | Mechanical micro-drilling, electrical discharge machining and laser beam machining | Micro-drilling via mechanical methods presents enhanced mechanical, metallurgical, and geometrical characteristics when contrasted with laser and EDM techniques. |
6 | Singh, N., Talapatra, A., Junkaew, A., Duong, T., Gibbons, S., Li, & Arróyave, R. (2016)31 | NiTi alloy | – | The effect of alloying on the thermodynamic and mechanical properties of B2 NiTi–X structures are presented. |
7 | Ahmet Balcı, Adem Çiçek, Necati Uçak, & Kubilay Aslantas. (2024)32 | Ti6Al4V alloy | Conventional micro drilling and peck drilling | During the micro drilling higher thrust force, surface roughness, burr height, and tool wear were reported. The MQL condition significantly improved the hole quality during peck drilling. High speed machining found suitable for better hole quality. |
8 | Yunze Li, Zhijian Pei, Weilong Cong. (2025)33 | Silicon | Conventional micro machining and rotary ultrasonic micro machining | A comparative study was conducted during the micro machining of silicon using conventional machining ang ultrasonic machining. Using ultrasonic machining reduces the thermal problems created by conventional machining. The hole quality is comparably high using ultrasonic machining. The paper also provides the mechanistic model for identifying relationship between parameters and hole quality. |
