From: Real-time on-machine observations close to interelectrode gap in a tool-based hybrid laser-electrochemical micromachining process

Figure 8

Variation of intensity change (UA: arbitrary units) for ECM and hybrid laser in the regions of interest (ROI) (refer Fig. 4c for locations of regions of interest). ROI 1 and 2 are located beside the interelectrode gap on both sides of the tool and indicate the combined rate of generation of reaction by-products and bubbles. ROI 3 indicates the rate of bubble generation as H2 bubbles migrate upwards along the tool (cathode). Intensity variations in (a) Tool-based ECM process at 20 V (b) Tool-based hybrid laser-ECM process at parameter combination 20 V/30 µJ and (c) 20 V/60 µJ.
