【 摘 要 】

Problem statement: In die and mold industries, surface roughness of the dies and moldsproduced will determine the end product quality. Therefore, the desired finish surface was specifiedand the appropriate processes were selected to reach the required quality. Among many contributors tosurface quality problem, backcutting is one of the factors influencing the surface roughness.Approach: The aim for current research was to study the backcutting phenomena and their effect tothe surface roughness of work material, AISI H13 with hardness of 48 HRC during high speed endmilling. Machining performed on the Vertical Milling Centre (VMC) high cutting speed from 150-250m min^-1, feed rate 0.05-0.15 mm tooth^-1 and depth of cut 0.1-0.5 mm. The analysis and observation ofthe backcutting phenomena are done by using optical surface roughness machine. Results: The resultshown that the pattern of surface roughness was not sufficient enough to compare between the surfacewith backcutting and without backcutting and the backcutting phenomena were seen mostly incombination of medium to high cutting speed and medium to high feedrate.Conclusion/Recommendations: Further research is needed with incrimination of experiments andadjustments of parameters.
