摘要：

For the residual error problems of five-axis machining free-form surface of toroidal cutter, a tool path planning algorithm with maximum ISO-scallop due to directional distance theory was proposed based on traditional ISO-scallop algorithm. Firstly, the initial lateral spacing distance of the known cutter contact (CC) point was calculated according to differential geometry theory, and the adjacent CC point was obtained in lateral direction. And then the actual scallop height of the adjacent CC point was calculated by scallop error calculation model based on the directional distance theory. Finally, the maximum ISO-scallop of the adjacent tool path was planned through the iterative calculation. Repetitions went on until the tool paths of the whole surface were obtained. The experimental results show that compared with the commercial software MasterCAM 9.0, the algorithm may greatly reduce total length of tool paths while ensuring the quality of surface machining, and improving the processing efficiency. © 2017, China Mechanical Engineering Magazine Office.
