| 摘 要： | 针对不同曲面的环形刀多轴加工,提出了最大步距计算的数学模型,建立了残留高度为常数时步距与刀轴倾角之间的函数关系,通过函数关系推导出最佳步距的值。实验表明,该算法在保证加工精度的前提下,能有效缩短加工刀轨路径,提高加工效率。

| Abstract: | The theoretical model of the maximum stepover estimation is established for different cases on the machine surface profile using the end-filleted cutter in multi-axis machining.The function between the stepover and inclination angles of tool axis is constructed at constant scallop-height.According to the equations the optimum stepover is derived.Experimental results show that the presented algorithm is feasible.It can obtain shorter tool path and improve the quality of machining. |
