摘要
滚花凸辊等类型的复杂零件一般在四轴机床上进行加工。为了提高此类零件的粗加工效率,研究了在NX CAM软件中将三轴刀路转化为四轴刀路的方法。该方法通过定制的后处理将加工效率高的二维刀路输出刀具轨迹点的坐标文件,然后通过这些点生成样条曲线,并将样条线缠绕在圆柱面上,作为NX CAM多轴粗加工的驱动曲线。通过Vericut仿真和实际加工证明,方案可行,弥补了NX CAM现有多轴加工策略粗加工效率低的缺点。
Complex parts such as knurled rollers are generally machined on four-axis machine tools.In order to improve the rough machining efficiency of such kind of parts,how to convert the three axis tool path into four axis tool path in NX CAM software is studied. This method outputs the coordinate files of the tool path point of the high processing efficiency two-dimensional tool path through the customized post-processing. Then the spline curves are generated through these points, and the spline lines are wrapped on the cylindrical surface as the driving curves of the NX CAM multi axis rough machining. Through Vericut simulation and actual machining, it is proved that the scheme is feasible,which makes up for the low roughing efficiency of the existing multi-axis machining strategy of NX CAM.
