Special Issue Information

A recent trend in technology and scientific research is to push further on the miniaturization of devices and components and to produce high-precision parts with severe geometric constraints. The need to fabricate components with such complex geometrical and dimensional characteristics has led to greater attention towards micromanufacturing techniques. Among the various technologies available for micromanufacturing, micro-EDM (electrical discharge machining) is widely used in micro-hole machining because of its high precision and negligible contact stresses. However, there are still some drawbacks related to the use of this technology in microdrilling; in general, high tool wear ratio, low erosion speed, aspect ratio and downsizing limits, geometrical and dimensional constraints are still noteworthy aspects in which improvements are constantly sought. This Special Issue aims to deepen the critical aspects mentioned above and, in particular, will focus on the following topics:

- Influence of the process parameters on both the process and the product performance;

- EDM solutions for achieving holes with very small diameters or high aspect ratios;

- Effect of electrode materials and characteristics on the micro-EDM drilling performance;

- Application of micro-EDM drilling to innovative/advanced materials such as ceramic materials;

- Characterization of micro-holes;

- Use of nonconventional dielectric fluids and powder mixed fluids;

- Integration of EDM and other technologies in micro-EDM drilling;

- Issues concerning the sustainability of the EDM process applied to micro-drilling;

- Theoretical aspects and modelling.

In micro electrical discharge drilling, regression models are commonly used for predicting the material removal rate (MRR) and tool wear rate (TWR) from the applied processing parameters. However, these models can be inaccurate since the processing parameters might not always be representative of the actual machining conditions, which depend on several other factors such as the tool length or gap flushing efficiency. In order to increase the prediction accuracy, the present work investigates the capability of data-driven regression models for tool wear and material removal prediction. The errors in predicting the MRR and TWR are shown to decrease of about 65% and 85% respectively when using data collected through process monitoring as input of the regression models. Data-driven approaches for in-process tool wear prediction have also been implemented in drilling experiments, demonstrating that a more accurate control of the hole depth (50% average reduction of the depth error) can be achieved by using data-driven predictive models.
