Study on Deformation Control of Thin-walled Ring Parts During Machining

针对薄壁零件加工过程中受夹紧力、切削力作用易产生变形问题,以薄壁圆环零件为研究对象,优化设计及加工工艺、装夹方式和专用夹具,通过弹性力学分析计算得出圆环零件在各道工序所能承受的最大压力,控制各道工序所需夹紧力大小。运用UGNX10软件对圆环零件各道工序工况进行有限元模拟仿真验证理论计算结果。将上述方案、计算结果运用于生产实际,圆环零件加工精度得到保障。

In view of the clamping force in the process of thin-walled parts processing, the deformation problem caused by cutting force, with thin wall ring parts as the research object, the optimization design of the machining process, the clamping methods and special fixture, calculated by the elastic mechanics analysis circle parts in each working procedure can withstand maximum pressure, control the size of each procedure required clamping force. UGNX10 software was used to verify the theoretical calculation results by finite element simulation of each working condition of the ring parts. The above scheme and calculation results are applied to the actual production, and the machining accuracy of the ring parts is guaranteed.
