摘　　要：机械零件尽管多种多样,但均是由一些诸如外圆、内孔、锥面、平面、螺纹、齿形等常见形状特征所组成。因此,合理选择常见形状特征的加工方案,是正确制定零件加工工艺的基础。提出了基于特征的二级加工方案决策体系,建立了基于零件特征的加工方案评价指标体系,并采用灰色关联分析对特征加工方案进行优化分析和计算。最后以单特征圆柱孔的工艺方案决策为例,证明了该方法的实用性。Though parts exist in different shapes and sizes,they consist of usual shape-features such as cylinder,cone,plane,thread,gear,etc.It is important to select the reasonable scheme of the process decision-making to establish part process.This paper puts forward a two level processing plan and establishes a appraisal index system on features to optimize the processing plan through the grey relation analysis.At last,the process decision-making on holes taken for example to validate its feasibility.
