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...

An entrainment defect (also known as a double oxide film or bifilm) acts void containing an entrapped gas when submerged into light-alloy melt, thus reducing the quality and reproducibility of final castings. Previous publications, carried out with Al-alloy castings, reported that this trapped could be subsequently consumed by reaction surrounding volume negative effect defects. Compared Al-all...
