Abstract
AbstractThis paper presents an approach for the determination of the optimal machining parameters (spindle speed, feed rate and depth of cut) in ball-end milling process of carbon fiber-reinforced plastics (CFRP). In this case, considering the machining force and surface roughness as the constrains, maximum material removal rate is created through coupling response surface method (RSM) and particle swarm optimization (PSO). Many experiments on CFRP were conducted to obtain machining force and surface Roughness values, and then analysis of variance was performed. In order to predict constrains values, RSM was selected to create mathematical relation between machining parameters and constrains. The material removal rate constituted the main function for PSO and machining force, and also surface roughness were applied to the input function of PSO. In this study, the function was optimized by PSO code, and the optimum parameters were obtained. Finally, the results of PSO were tested experimentally and compare...

Many modern industries, such as aerospace, underwater, and transportation application, require unusual combination properties which cannot be met by the conventional materials such as metals, ceramics, and polymers
The investigation of chip formation and material removal mechanisms in carbon fiber-reinforced plastics (CFRP) machining provides the essential knowledge to understand the interaction between CFRPs and tools along with providing insights into the development of cutting theories
The curves of machining force versus feed rate for various spindle speeds have been shown in Figure 6 for depth of cuts 2, 6, and 8 mm
