마이크로 표면 형상 시뮬레이션과 실제 금형 가공면 비교

Abstract

The objective of this study is to generalize the micro surface topography prediction algorithm researched in the laboratory to mold machining industry. The micro surface topography including the geometry of the tool, surface inclination angle, and cutting conditions was simulated using developed software. A satisfactory agreement was observed between the literature and the simulation results. In the factory, the average surface roughness of the machined surfaces was measured using surface roughness measuring tester SJ-210, and the 3D surface topography was measured using replica tape and the New View 7300 system in the laboratory. The error of the measured areal surface roughness of the molds with respect to the prediction result is 30%. The comparison results indicated that the established micro surface topography software should be improved to predict the surface roughness of the mold in industry.
