For example, laser cutters do not make direct contact with material, rely on high-energy power sources, have tighter cutting tolerances, and are generally automated to maximize precision. A laser device fires a concentrated stream of photons onto a precise area of the work piece in order to ...
The hardness value of the various textured shape surface is higher than the others because mechanism of material removal for pattern is melting and evaporation, after applying an intense heat sudden cooling takes place. This might be altering the microstructure and enhances the hardness of the ...
