摘　　要：铝蜂窝在使用传统加工技术加工时容易受损。为提高铝蜂窝加工表面质量,建立铝蜂窝超声加工切削力数学模型和仿真计算模型,研究网格尺寸对仿真结果的影响,确定合适的网格尺寸,并分析不同加工参数下的切削力和表面形貌。综合评价后选用0.2 mm的网格进行仿真模拟,结果表明随着进给量、主轴转速和切削宽度数值分别增大,加工损伤明显呈下降趋势。研究结果为铝蜂窝超声辅助加工的数值模型、仿真和试验提供了基础。Traditional machining techniques often result in damage to the aluminum honeycomb.In order to improve the surface quality of aluminum honeycomb machining,the numerical and simulation models of cutting force in ultrasonic-assisted machining of aluminum honeycomb were established.The influence of mesh size on simulation results was investigated to determine an appropriate mesh size.Furthermore the cutting forces and surface morphology were analyzed for different machining parameters.After a thorough evaluation,a mesh of 0.2 mm was chosen for the simulation.The results show that there is a clear reduction in machining damage with increasing the feed rate,spindle speed,and cutting width values.This conclusion can provide reference for mathematical model,simulation and experiment of ultrasonic-assisted machining of aluminum honeycomb.
