摘要
以实现复杂零部件快速增材和高精度减材的复合加工为目的,开发了五轴联动增减材混合加工中心。在此基础上阐述机床增材与减材的设计开发过程及增减材集成控制原理,分析机床整体精度的控制方法,进行了相关增减材试验。采用航空发动机叶轮和五轴机床验收标准中的圆锥台试件做减材试切加工,针对叶轮叶片及S试件进行增材加工的工艺算法优化和对应的增材试验,初步得到了较符合预期的加工效果。
In order to realize the compound process of rapid forming and high precision milling for complex pieces,our assignment group developed a five-axis additive-subtractive hybrid machining center. Based on the five-axis additivesubtractive hybrid machining center, the developing process and integrating control principles are expounded, and the control method of total precision is analyzed. Furthermore, the relevant experiments were carried out. The tapered bench specimens in the acceptance criteria of aerospace engineering impeller and five-axis machine tool are used for material subtraction trial manufacturing. We carried out some additive manufacturing experiments for the impeller blades and S specimens, algorithms optimization of generating additive manufacturing path were also applied. The expected machining performance is preliminarily accomplished.
