Based on the characteristics of the cutter axis vector data, the minimum optimization model and algorithm of the cutter axis vector directed graph were proposed. This method can get global minimum cutter axis vector variation of cutter axis vector sequence and improve the computational efficiency of the algorithm by using the boundary of the feasible region of cutter axis vector joining in the directed graph calculation. Simulation and data analyses show that the proposed method improves the continuity and smoothness of cutter axis vector in a certain extent, and also has certain applicability in its optimal tool posture along the boundary of the feasible region. 语种: 中文 Citation statistics: 内容类型: 期刊论文 URI标识: http://ir.sia.cn/handle/173321/17153 Appears in Collections: 装备制造技术研究室_期刊论文
