Abstract

Problem statement: In die and mold industries, surface roughness of the dies and molds produced will determine the end product quality. Therefore, the desired finish surface was specified and the appropriate processes were selected to reach the required quality. Among many contributors to surface 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 to the surface roughness of work material, AISI H13 with hardness of 48 HRC during high speed end milling. Machining performed on the Vertical Milling Centre (VMC) high cutting speed from 150-250 m min-1, feed rate 0.05-0.15 mm tooth-1 and depth of cut 0.1-0.5 mm. The analysis and observation of the backcutting phenomena are done by using optical surface roughness machine. Results: The result shown that the pattern of surface roughness was not sufficient enough to compare between the surface with backcutting and without backcutting and the backcutting phenomena were seen mostly in combination of medium to high cutting speed and medium to high feedrate. Conclusion/Recommendations: Further research is needed with incrimination of experiments and adjustments of parameters.
