摘要
为降低整体叶轮类零件最终抛光工序的劳动强度、提高加工效率,切削加工工序有很高的尺寸精度要求,文章以提高切削加工仿真尺寸精度为目的,以UG为平台进行了叶轮零件的建模及加工轨迹规划,在Vericut软件中构建了DMU50五轴数控机床的加工仿真环境。将数控加工仿真与刀具路径轨迹规划结合研究,通过仿真检查结果反复修正刀路轨迹,最后设计生成的刀具路径轨迹在仿真加工中残留在0.15mm以内,过切在0.10以内,有效的降低了抛光工序加工余量,可以减少抛光工序工作量,提高抛光效率,降低由于抛光余量大造成烧伤的危险。
To lighten the burden of polishing process and improve the efficeiency, high dimensional precision is demanded during maching cutting. For the purpose of improving dimensional precision, based on commercial software UG, this paper modeling an integral impeller and generate tool path for the inpeller. A manufacturing simulation environment for DMU50 5-axis NC machine tool is built with Vericut. The paper researchs the manufacturing simulation and tool path generation as integral. The tool path is revised and corrected according to the simulation result. At last, the cutting result in simulation with residual less than 0.15 mm and overcut less than 0.10 mm. The margin and burden for polishing process is lightened and the polishing efficiency is promoted. The danger of surface burning is also reduced.
