摘要
选取螺旋铣孔过程中切削速度、轴向进给以及偏心量为对分层产生主要影响的工艺参数。为得到建模所需数据,切削实验采用三因素三水平全因素实验设计,并使用螺旋铣孔工艺专用涂层刀具。基于实验数据,通过多元非线性回归-响应曲面法,建立分层缺陷和螺旋铣孔工艺参数之间的数学模型,并用MATLAB画出响应曲面图,最后通过曲面图直观地分析了三种参数对分层的影响,指出两个导致分层的主要因素。
In this paper,the cutting speed,central offset,axial feed rate were considered as the three process parameters affecting the delamination. To get the cutting parameters database and the corresponding delamination,a large amount of experiments were planed using three levels three-factor full factorial design of experiments( FFD).Specific tool for helical milling with Ti Al N coating was used in the experiments. Based on the experimental results,a multi-variant non-linear regression model was developed with the statistical software SPSS. With the mathematical model,three response surface figures can be drawn with MATLAB. Through the analysis of the figures,the two major factors influencing the delamination were pointed out.
