摘要
为探究Nomex蜂窝芯圆盘锯齿刀超声切削过程中切削参数与切削力热的映射关系,开展圆盘锯齿刀超声切削Nomex蜂窝芯复合材料仿真及试验研究,分析主轴转速、进给速度、切削宽度和切削深度对切削过程中切削力热的影响,建立了切削温度随进给速度、主轴转速的一次回归模型。结果表明:所建立仿真模型最大误差为11.2%,可有效预测切削力与切削温度;三向切削力随着切削宽度,切削深度,进给速度的增大而增大,随着主轴转速的增大而减小;进给速度与主轴转速对切削温度影响显著;实际加工中,应采用大切削深度与切削宽度增加切削效率,采用小进给速度和主轴转速以降低切削温度,减少刀具磨损。
In order to explore the mapping relationship between cutting parameters and cutting force heat in ultrasonic cutting of Nomex honeycomb core disk serration cutter,the ultrasonic cutting of Nomex was carried out The simulation and experimental research of honeycomb core composite material,the influence of spindle speed,feed speed,cutting width and cutting depth on cutting force heat during cutting process is analyzed.A regression model of cutting temperature with feed speed and spindle speed is established.The results show that the maximum error of the model is 11.2%,which can effectively predict the cutting force and temperature;the three-way cutting force increases with the increase of cutting width,cutting depth and feed speed,and decreases with the increase of spindle speed,and the feed speed and spindle speed have significant influence on cutting temperature.On the premise of reliable fixation,it is beneficial to increase cutting efficiency by using larger cutting depth and cutting width.The lower feed speed and spindle speed are adopted to reduce cutting temperature and reduce tool wear.
