摘　　要：利用有限元软件ANSYS对八机头数控雕刻机切削力进行谐响应分析,首先求出八个主轴切削力在X、Y、Z方向的谐响应幅值变化曲线和数据,然后求出八个机头的动刚度并对其进行研究分析。Harmonic response analysis of the cutting force of eight-head CNC engraving machines with finite element software is made,with the harmonic response amplitude value change curve and data of the cutting force of eight spindles in the directions of X,Y and Z obtained,then the dynamic stiffness of eight heads obtained,followed by the study and analysis of it made.

关 键 词：动刚度 八机头数控雕刻机 切削力 谐响应
