Effect of textures on machining of carbon steel under dry cutting condition

Abstract

The effect of cutting performance was investigated using uncoated plain andtextured tungsten carbide tools in dry machining of carbon steel.Texture namely straight line,zigzag and plus profiles was created on flank face of the uncoated tungsten carbide tool. This textured tool was designed and fabricated by Neodymium-doped Yttrium Aluminium Garnet ND-YAG laser machine.Also it was evident with scanning electron microscopy analysis. In further design of experiment was carried by taguchi method by using L9 orthogonal array for varying cutting speed, feed rate, depth of cut to perform the machining experiment. The cutting force,surface roughness and cutting temperature were measured in which it depicts that microscale textured tools improves the machining characteristics to a greater extent when compared with untextured tool.It can be effective in all manufacturing industries provide an eco friendly environment since no coolant is required due to which it becomes pollution free.
