综合考虑零件工艺设计经验和制造稳定性的工艺路线决策

Decision-Making of Process Route Considering Process Planning Experience and Manufacturing Stability

已有的工艺路线决策过程都缺乏对零件的工艺设计经验及对企业当前实际生产情况的充分考虑,造成最终生成工艺路线的适用性和有效性较差,往往需要进行二次修改.为了解决上述问题,提出一种综合考虑零件工艺设计经验和制造稳定性的工艺路线决策方法.首先建立了工艺约束矩阵,并通过工艺约束矩阵的连续迭代相乘生成了零件的初始工艺路线;然后将初始工艺路线与典型工艺路线进行匹配,建立了基于工艺设计经验的工艺路线评价指标;再对当前企业生产线网络的稳定性进行分析,建立了基于制造稳定性的工艺路线评价指标;最后在综合考虑工艺设计经验评价指标和制造稳定性评价指标的基础上,通过应用集对分析理论实现了对零件最终工艺路线的决策.实例验证结果表明,该方法是有效的.

The traditional decision-making process of process route had been lack of consideration of process planning experience and the influence in production, which result in that the generated process route may cause worse suitability and effectiveness, and consequently the generated process route must be modified. To solve the above problems, a decision-making method of process route considering process planning experience and manufacturing stability was presented. The process constraint matrix was established, and initial process routes was obtained through applying matrix iteration multiplication. The evaluation index based on process planning experience was established by using initial process routes to match the typical process Route. The evaluation index based on manufacturing stability was established by analyzing the instability of enterprise manufacturing network. Then on the basis of considering the two evaluation indexs, the final process route was set by using Set Pair Analysis. Experimental results showed that the effectiveness of proposed method was verified.
