【摘要】 对T形截面铸件经加工后产生的变形进行试验研究并给出操作简单精度高的测量方法.结果表明,不同的冷却方式下其变形量不同,空冷产生的变形量最大为116μm,去应力退火产生的变形量较小为50μm.更多还原

【Abstract】 Measuring technique of deformation of a T-shape cross-sectional casting when machined is studied and a simple,accurate measuring method is given.Results indicate that the deformation is different under different cooling.The maximum deformation under air cooling is about 116 μm,and the deformation by stress relief annealing is slightlly less,only 50 μm.更多还原
