عنوان انگلیسی Experimental study of milling forces in high-speed milling of bidirectional c/c composite and development of a quadratic model for this reason
چکیده انگلیسی مقاله This research investigates the effect of feed rate, cutting speed, and orientation of fabric layers on milling forces in high-speed milling of bidirectional C/C composite using the Al2O3 grinding tool in order to decrease the machining time and increase the tool life based on the response surface method (RSM). For this reason, the above-mentioned parameters were assumed as the input parameters which their effects were investigated on the machining forces (using a milling dynamometer) and tool wear using the central composite design of RSM. Two quadratic models were developed to predict normal and tangential forces in high-speed milling of bidirectional C/C composite. The developed models were then evaluated using three experiments. The results also showed that the orientation of the composite layers has the greatest effect on the milling forces and tool wear after which the tool cutting speed and feed rate respectively. The lowest milling forces were observed at the orientation of (0°,90°), a feed rate of 0.5 m/min, and the cutting speed of 4521.6 m/min.
