摘要:
航空与机床行业的大型复杂运动件普遍采用整体式结构,其装配与加工精度提高离不开金属切削加工技术的研究。将CAE技术与金属零件加工工艺相结合,针对大型金属整体件加工提出了一套改善金属零件加工精度的系统解决方案; 并采用测试技术验证该解决方案的可行性。切削加工工艺仿真及切削力测试对比结果表明,采用仿真技术进行工艺参数优化是可行的; 通过保持现有的切削材料速率、提高主轴转数,可以降低刀具的周向、进给方向的切削力近50℅。采用该技术可有效进行参数优化及并指导工艺改进。
Abstract:
The large and complex movable parts in aviation and machine tools industries are commonly of integrated structures, and to improve the accuracy of their assembly and processing, the metal cutting technology must be studied. By combining CAE technology with the processing technology of the metal parts, this research puts forward a systemic solution to improving the processing accuracy of the metal parts; and the testing technologies are applied to validate the feasibility of the solution. Results of cutting force machining process simulation and test comparison show that: the process parameter optimization about simulation technology is feasible; by maintaining the current material cutting rate and increasing spindle speeds,the circumferential direction of the tool and the feeding direction of the cutting force can be reduced by nearly 50℅.The technique can be used to effectively optimize the parameter and guide the processing improvement.
