摘　　要：分析了夹具评价对逆向工程的作用,由于逆向工程中几何测量误差导致夹具设计尺寸可能不精确,为了保证加工精度,需对夹具进行评价。在众多的夹具评价指标中,以定位误差分析和夹紧力估算为例,对夹具进行了必要的工程分析,如果夹具功能满足要求,即便几何尺寸有些误差,也可以使用。The role of the fixture evaluation on reverse engineering is analyzed Since the geometrical measuring errors in reverse engineering lead to fixture design size that may imprecise. For the machining accuracy, the evaluations on the fixture are required,of the most evaluation index of fixture, for example, locating error analysis and clamping force estimation,have a engineering analysis necessarily on the fixture,if the functions of fixture are qualified, even if there are a few geometrical measuring errors, it can be .used as well.
