Investigation of the effects of machining parameters on surface integrity in micromachining

Abstract In this study, the effect of cutting conditions on surface integrity was investigated in micromilling magnesium alloy (AZ91). Microtool diameter, speed, feed rate, and depth cut parameters are used. These variables were at three different levels with Taguchi L 9 experimental design method. The least-best objective function As a result experiments, roughness values obtained. It has been determined that effective parameters. After evaluating results obtained, variance regression analyses performed. Based analysis variance, 58.73% rate found for 1.0 mm diameter tool, other hand, 0.8 to be an parameter 53.6%.
