摘　　要：由于目前现有的金属零件加工存在较大的加工误差,为此提出金属零件的铣床加工工艺分析。首先需要根据金属零件加工要求,选取合适的加工原材料,并利用RH炉对金属原料进行锻造;然后利用铣床按照金属零件加工图纸对金属零件进行粗车;最后对金属零件表面进行渗碳及精加工,以此完成金属零件的铣床加工。经实验证明,设计工艺加工误差小于传统工艺,更适用于金属零件的铣床加工。Due to the large machining error in the current metal parts processing,the milling process analysis of metal parts is proposed.Firstly,according to the processing requirements of metal parts,we need to select the appropriate processing raw materials,and use RH furnace to forge the metal raw materials;Then rough turning of metal parts is carried out by milling machine according to metal parts processing drawing;Finally,the surface of the metal parts is carburized and finish machined to complete the milling process of the metal parts.The experimental results show that the error of the designed process is less than that of the traditional process,and it is more suitable for milling of metal parts.
