In the periodic table, it is mentioned that the closer atoms or just intermediate atoms to Carbon are Boron & Nitrogen. Now Scientists also confirmed that Boron & Nitrogen can form a perfect nanotube structure. Boron Nitride Nanotube (BNNT), possesses a similar tubular nanostructure as carbon nanotube (CNT) but it is composed of the B-N atoms hexagonally. BNNT possesses various properties & its properties can show different-different behavior according to the conditions & environment. Here we are discussing the temperature & its effects on the mass sensing capabilities. Along with this, the various configurations of the BNNT’s are also discussed simultaneously. Due to their superior properties & high effectiveness, these are widely used all over the world.

In this paper, Study on Material expulsion rate and Surface Roughness of H13 die tool using Wire cut EDM process is focused. H 13 chromium hot work steel is far and wide used in hot and freezing work tooling purpose. Due to its excellent amalgamation of high robustness and fatigue resistance H13 is used more than any supplementary tool steel in tooling applications. The H-13 hot die-hard substance dimension 103.70 mm x 13.95 mm has been utilized as a work section substance in favor of the current research, wire electrode of brass having standard diameter 0.25 mm is used as electrode. Four Parameters (TON, TOFF, WF and voltage) are chose to consider its impact on cutting rate and surface harshness. Taguchi Plan of technique is used in the experimentation & analyze by Minitab 15 programming. Observations brings voltage is the most noteworthy boundaries on SR where Ton and Toff are less critical and also observed that MRR amplify with enhance in Ton and WF and diminish on escalating of Vg and Toff.

Good surface quality and the processing of complex shapes are the essential requirements in various manufacturing industries today. To achieve this, scientists are switching from a variety of conventional machining methods to non-traditional machining processes. Wire EDM (WEDM) is one of the most common non-traditional machining processes. In terms of quality, surface roughness (SR) is an important performance parameter in machining processes. The article summarizes the parameters that affect surface roughness.
