In recent years, 3-axis control machining has been generally utilized for the roughing process. However, this approach is not efficient for roughing complicated shapes, such as parts with overhanging structures, due to the necessity of resetting the workpiece. To address this inefficiency, 5-axis control machining is developed, yet a specific roughing procedure for this method has been absent. This study explores the application of 3+2-axis control machining, which combines 3 translational axis movements with 2 rotational axis adjustments to optimize tool axis vector determination. The methodology involves a multi-stage decision process to ascertain suitable tool axis vectors and appropriate tool diameters. Initially, candidate tool axis vectors are evaluated based on machinable area calculations for each vector. Subsequently, optimal combinations of tool axis vectors and diameters are determined using a performance index. The proposed method's efficacy is validated through machining experiments carried out on an impeller. This approach aims to enhance the rough machining process significantly, improving efficiency in complex geometric configurations.
