【摘要】：切削力是高速切削過程中重要物理量之一,直接影響到加工質(zhì)量和刀具壽命。文章采用中心復(fù)合響應(yīng)曲面法建立了碳纖維增強(qiáng)復(fù)合材料(carbon fiber reinforced polymer,CFRP)高速銑削過程切削力模型,并用方差分析對(duì)模型及回歸系數(shù)進(jìn)行了顯著性檢驗(yàn),分析了主軸轉(zhuǎn)速、每齒進(jìn)給和切削深度對(duì)切削力的影響規(guī)律,為高速銑削過程中切削參數(shù)的選擇及切削力的控制提供了試驗(yàn)依據(jù)。試驗(yàn)結(jié)果表明:該模型能較好地預(yù)測切削力,切削深度和每齒進(jìn)給對(duì)切削力的影響較大,切削力隨著切削深度或每齒進(jìn)給的增大而增大,主軸轉(zhuǎn)速則對(duì)切削力影響不是很大。
[Abstract]:Cutting force is one of the important physical quantities in high speed cutting process, which directly affects machining quality and tool life. In this paper, the cutting force model of high speed milling process of carbon fiber reinforced composite material (carbon fiber reinforced polymer,CFRP) is established by using the central composite response surface method. The significance of the model and regression coefficient is tested by variance analysis, and the rotation speed of spindle is analyzed. The influence of feed and cutting depth of each tooth on cutting force provides experimental basis for the selection of cutting parameters and the control of cutting force during high speed milling. The experimental results show that the model can predict the cutting force, the depth of cutting and the feed per tooth have a great influence on the cutting force. The cutting force increases with the increase of the cutting depth or the feed per tooth, while the spindle speed has little effect on the cutting force.
