面向零件群加工的可重构制造工艺设计方法

Process Designing Method of Reconfigurable Manufacturing for Part Family

将可重构制造工艺方案设计与可重构机床结构特点相结合,以所建立的工序单元、工序段概念为出发点,通过对零件族加工信息的程式化处理,建立了加工信息矩阵,给出了工序单元创建方法和工序段方案的划分方法,通过交叉双向组配方式获得了多种满足加工要求的工艺方案;以所建立的工艺方案相似性判定模型为基础,找出可供可重构机床结构重构的合理工艺方案,为实现零件群内部加工柔性化提供了科学依据。最后以发动机缸盖零件群加工工艺设计为例,验证了方法的有效性。

Reconfigurable manufacturing process design was combined with characteristics of reconfigurable machine tools. Beginning with the proposed process unit and process section, the processing information matrix was built through the processing information formulation. Then the processing unit was established and the division method of process section was proposed. Through the cross two-way method, a variety of process schemes which meet the reconfigurable manufacturing requirements were obtained. Based on the similarity judgment model of processing plan, the reasonable processing schemes for the reconfiguration of reconfigurable machine tools were found out, which provided scientific basis for realizing the manufacturing flexibility in part family. Finally, an example of processing design for the cylinder front covers family was given to verify the validity of the proposed processing method.
