According to the value of weighted mean roughness the priority of different characteristic information can be distinguished, so the proposed method possesses strong tolerant ability.
按加权平均粗糙集的大小区分层内各特征信息的优先级，具有很强的容错能力。

Flange surface roughness of the influence, especially sealing effect when using the soft cushion, seal surface coarse degree value big are caused by the leak is one of the main reasons why.
It may be used effectively in deburring, reducing the value of surface roughness, chamfering. improving conditions of surface residual stress and surface hardness and reducing greatly microdefects.
