摘　　要：精密弹簧片为惯性仪表的关键零件,其成型与校平工艺对仪表的测量精度有重大影响。从设计要求出发,针对传统加工工艺中难点问题制定合理工艺路线,尤其对弹簧片成型与校平等工艺进行详细分析,确定了更优的工艺路线。采用优化后工艺加工的弹簧片尺寸、形位公差等均可满足设计要求,且改进后工艺加工过程在零件断面表面形成加工硬化层,增强了零件的疲劳强度。As the most import part of inertial device,the quality of sheet spring affects measure precision.Base on the design,a appropriate technics path is established in allusion to machining difficulty.It is especially introduced about molding and flattening process in the paper.The results show that optimized process could satisfy the designing technical characteristics,and the work-harding surface formed by the process improves fatigue resistance of the parts.
