为进一步减少曲轴在加工后的摆差并使之达到最佳状态,即勿需冷校而达到产品图的摆差要求(0.05mm),我们对工序的摆差形状及其组合关系进行了研究。结果表明:在合理选择加工条件和正确调整工艺系统的情况下,其摆差形状和组合关系具有固定的类型,且其值最小;反之,则没有固定的类型,且其值增大。 In order to further reduce the crankshaft in the machining after the poor and make it to the best condition, that is, without the cold to achieve the product requirements of the swing (0.05mm), we have the process of the swing shape and the combination of relations were studied . The results show that under the condition of reasonable selection of processing conditions and correct adjustment of the process system, the shape and combination of the deviations are of a fixed type with the smallest value; on the contrary, there is no fixed type and its value increases.
