EFFECTS ON FORCES AND SURFACE ROUGHNESS DURING MACHINING INCONEL 718 ALLOY USING MINIMUM QUANTITY LUBRICATION

Abstract

Turning operations are one of the most versatile secondary manufacturing processes. In industry, manufacturing processes are contrived and improved in order to obtain maximum quality and minimum cost. Requirements of higher machining quality and manufacturing efficiency have led to a great deal of researches aimed at controlling and planning the metal cutting processes. In manufacturing industries new techniques have been developed to improve manufacturing performances through better processes, and use of advanced cutting tools. However, the environmental aspects are increasingly becoming a significant issue. Thus, in parallel with manufacturing process’ optimization, efforts must be made to reduce the impact of industrial activity on environment and health. The increasing requirements for environment-friendly cutting processes enabled use of new techniques like the minimal quantity or even the complete omission of cutting fluids. The most promising solution to these requirements is MQL machining, which has been performed in the metal removal process such as milling, drilling and turning. In the present study we compared the effect of forces and surface roughness data during turning of Inconel 718 under dry,
