陶瓷零件的机械切削加工

摘要

用数据包络分析法评价陶瓷的可加工性,构造数学规划模型,求出决策单元的最优解.结合陶瓷材料的机械加工难点,探讨了陶瓷车削、磨削、钻削等机械切削加工工艺的技术要点.通过切削正交试验,得到刀具的前角、后角、主偏角、副偏角、刃倾角、刀尖圆弧半径及切削速度、吃刀深度、进给量的参考值,优化加工工艺参数,达到较好的加工效果.%The machinability of ceramics is evaluated by data envelopment analysis, and mathematical programming model is constructed, then the optimal solution of decision-making unit is found. These reference values of the tool rake angle, clearance angle, tool cutting edge angle, minor cutting edge angle, tool cutting edge inclination angle, tip ARC radius and cutting speed, back engagement and the range of feeds are obtained through orthogonal cutting test, whose processing parameters are optimized, then better processing results are achieved. Considering the problem of machining of ceramic materials, the techniques of mechanical cutting process, ceramic turning, grinding, drilling, are discussed.
