TO EXPLAIN OF TOOL LIFE BY CAUSE AND EFFECTDIAGRAMS, ANALYSIS OF SURFACE ROUGHNESS AND TOOLLIFE(M.Sc. Thesis)Ferit İŞBİLİRGAZİ UNIVERSITYINSTITUTE OF SCIENCE AND TECHNOLOGYMay 2006ABSTRACTData that where in printed literature were used in this study. Thefactors that effecting tool life in turning suggested by cause and effectdiagrams. The effects of various parameters from used data examinedon surface roughness and tool life. Surface roughness and tool lifemodeled by examined parameters. Cutting speed, material hardness,insert radius and feed rate found to have significant effect on thesurface roughness, but cutting fluid and depth of cut found not tohave significant . Cutting speed, material hardness, feed rate anddepth of cut found to have significant on the tool life. The R squares ofregression equations based on the prediction of surface roughnessand tool life found 0,591 and 0,952 , respectively.Science code : 708Key word : Tool life, cutting tool, cause and effect diagramPaper number : 74Adviser : Prof. Dr. Muammer NALBANT
