Description
Renu Kiran Shastri and colleagues fine tune a spark based cutting method for shaping titanium parts used in medicine, in a 2026 study. The alloy is strong and rust proof, yet its hardness defeats normal drills and mills. Reverse spark machining carves pillar arrays into the metal with no tool contact, using three electrode metals for comparison.
Six settings were varied in a planned grid of runs, from pulse length to flushing pressure. The team scored surface roughness, hardness, damaged layer depth, and crack counts under a microscope. A ranking method merged the scores, and a firefly inspired search found the best blend of settings. A confirmation run at those settings improved results by about seven percent over the starting point, giving shops a tested recipe.
