Abstract

Machining processes are the most important method used in production in the industry. In these processes, the friction in tool-chip surface during the MACHINING is one of the affecting factors on surface quality of work piece. The generated heat by friction augments the tool wear mechanism and increases the wear rate of cutting edge, which leads to reducing surface quality. The high ability of aluminum to built-up edge formation during MACHINING has the undesirable effect on the surface quality.In the present study in order to improve the cooling-lubrication conditions in MACHINING of 6061 ALUMINUM ALLOY, a new cutting tool created with micro-grooves on its rake face was developed to improve the cutting fluid transfer to MACHINING zone and reduce the friction between tool-chip surfaces.Two types of micro-grooves have been created by laser MACHINING process. Specimens by changing the MACHINING parameters and types of the applied cutting fluid to MACHINING zone were machined. The experimental results obtained from SURFACE ROUGHNESS survey and prepared images of work piece surface by scanning electron microscope (SEM) and optical microscope showed that by creating the microgrooves, the delivery conditions of cutting fluid to MACHINING zone has improved and its effect on reduction of SURFACE ROUGHNESS is clearly visible. By comparison of the results of two micro-grooves it was shown that direction of grooves is the most important parameter in its design, so that the perpendicular texture not only improves the surface quality but also increases the SURFACE ROUGHNESS compared to non-texture tool.
