摘要
主要从刀具让刀、刀具磨损、加工余量、加工刀轨及加工进给等方面分析了影响模具型面精加工精度的因素。提出了减小刀具与曲面法向的夹角、采用大而短的刀具、减小切深及提高转速、尽量采用顺铣加工、CNC程序重叠消除接刀台阶、前后工序的刀轨走刀方向一致等方法,有效提高了模具精加工的精度。
The factors like cutter back-off, tool wearing, machining allowance, tool path and machining feed that affect the mold surface finishing accuracy will be analyzed and methods proposed to improve the accuracy of the mold surface, so that the mold finishing accuracy could be effectively improved.
