摘　　要：玻璃纤维增强复合材料(GFRP)两相材料属性相差迴异,加工难度大。利用有限元仿真软件对玻璃纤维增强复合材料进行了研究,分析了刀具几何参数与切削力之间的关系。结果表明:当刀具前角由3°增大到12°时,切削力下降,但当前角由12°增大到15°时,切削合力和主切削力有微小上升趋势;当刀具后角从2°增加至12°时,切削力呈现下降趋势,从12°增加至22°时,切削力呈现增大趋势;当刃口半径由0.05mm增加至0.4mm时,切削力减小,刃口半径从0.4mm增加到1.2mm时,切削力增加。仿真得到的最合适刀具几何参数分别为前角12°、后角12°和刃口半径0.4mm。The properties of two phases of glass fiber reinforced composite materials vary greatly,making it difficult to process.Glass fiber reinforced composite materials is studied by finite element simulation software and the relationship between tool geometric parameters and cutting force is analyzed.The results show that when the tool rake angle increases from 3°to 12°,the cutting force decreases accordingly,but when the rake angle increases from 12°to 15°,there is a slight upward trend in the cutting resultant force and main cutting force.When the clearance angle of the tool increases from 2°to 12°,the cutting force decreases,and when it increases from 12°to 22°,the cutting force increases.When the cutting edge increases from 0.05mm to 0.4mm,the cutting force decreases.When the cutting edge increases from 0.4mm to 1.2mm,the cutting force increases.The most suitable geometric parameters for the tool obtained through simulation in this article are the rake angle of 12°,the clearance angle of 12°,and the edge radius of 0.4mm.
