**4. Conclusions**

This investigation has systematically probed the influence of input parameters on the corner radius and included angle of triangular micro cavities produced via microelectrical discharge machining (micro EDM). The empirical observations offer the following conclusions.

• A discernible relationship between the corner radius of the microcavity and the included angle was discerned as the corner radius expanded from 5 to 15 μm, resulting in an associated variation in the included angle from 62 to 67°. The dynamic response elucidates the pronounced sensitivity of the micro EDM process to modifications in input parameters, thus accentuating the paramount importance of precise parameter manipulation to attain the desired geometrical outcomes.
