The purpose of this study is to enhance the machine tool's processing capability by improving the machine tool from 4-axis to 4+2-axis, which endows the machine tool the ability to process impeller using the barrel cutter. We first analyzed the dynamic performance of the 4+2-axis machine tool with theory of mechanism, which demonstrates that the tool position has one optimizable parameter. Then, we derived the relationship among the half-linkage axis parameters, the tool position, and the linkage axis movement parameters, and obtained a method for solving the position at the cutter contact point. Based on the geometrical analysis of the complex surface, mechanical interference and the movement range of the machine tool, we provided a method to choose the parameters of two half-linkage axes when processing the impeller by using 4+2-axis, and deduced an algorithm for generating the tool path. We finally tested the tool path by experiments. The results show that the proposed 4+2-axis machining method for processing impeller blade is feasible and has promising production and application value.
