摘　　要：槽式刀盘是数控刀架重要的装刀装置,直接夹持刀具对工件进行加工,在一定程度上决定了数控刀架的整体性能。基于有限元法对刀盘进行静力学分析研究其力学特性,根据分析结果为提高刀盘的整体性能并减小质量节约制造成本,提出对刀盘在重量驱动下以刀盘的最大位移为约束利用序列二次规划算法进行多目标参数优化,优化后刀盘质量减轻了7.1%,最大应力降低了43.92%且最大位移降低了26.22%,一阶固有频率提高了45%,动态响应稳定性得到了改善达到了优化目标。对刀盘的分析优化研究可为相关研究及工程应用提供一定的理论依据。Groove cutter head is an important tool mounting device of CNC turret. It directly holds the tool to process the workpiece,which determines the overall performance CNC turret to a certain extent. Based on the finite element method,the mechanical properties of the cutter head are analyzed. According to the analysis results,the maximum displacement of the cutter head is taken as the constraint to optimize the multi-objective parameters of the cutter head and the rear cutter head.The mass is reduced by 7.1%,the maximum stress is reduced by 43.92%,the maximum displacement is reduced by 26.22%,the first natural frequency is increased by 45%,and the dynamic response stability is improved to reach the optimization goal.The analysis and optimization of cutterhead can provide theoretical basis for related research and engineering application.
