Surface finish machining optimization for 3D print

Abstract

The machining process has been conducted to get better surface results of a 3D print product. However, until now, there has been no optimization of parameters for the procedure. This study aims to obtain the optimal level of surface roughness in the machining process. A total of 27 experiments with the full factorial method were conducted (3 levels for three parameters). In this study, parameters to obtain surface roughness on the x and y-axes are different. On the x-axis, optimal surface roughness is achieved with 40 m / minute cutting speed parameters, 400 mm / minute feed rate, and 0.4 mm depth of cut. Meanwhile, on the y-axis, optimal surface roughness is obtained with 80 m / minute cutting speed parameters, 250 mm / minute feed rate, and 0.4 mm depth of cut.
