Structured process design method for discrete manufacturing industry

Abstract

The invention discloses a structured process design method for a discrete manufacturing industry. The method comprises the following steps: process service data are determined according to a process object, a process object model is built, structured process planning is carried out, and a corresponding process is designed; the consumption relation between the process object and a part, the assigned distribution relation between the process object and a resource object and a special relation between the process part and the resource object are verified; the structured process is designed and supported in a graphical environment, and a two-way interactive relation between a graphical tool and already-defined service data is built; and process nodes are selected, a process flow chart is generated based on an APQP object, and the process features and the control plan for PFMEA are built. For a whole enterprise production technology preparation process, consistency, effectiveness and reuse of the data are ensured; and a data base and a support mechanism are provided for visualization, analysis and optimization of a subsequent manufacturing process.

Description

technical field [0001] The present invention relates to a structured process design method for discrete manufacturing. Background technique [0002] Process technology and management have expanded from traditional production technology preparation to the entire life cycle of products, and formed manufacturing system engineering, integrated mechanical processing technology and management technology, and developed in the direction of parallelization and integration of process management and design . The traditional generative CAPP system only pursues the automation of process design, and it is difficult to popularize and apply it in the manufacturing industry. However, most CAPP products currently on the market overemphasize the editing and management of process specification cards, lack the analysis of the data of the process itself, and have problems such as the inability to realize process accumulation and avoid duplication of process design, mainly in the following areas:...

[0005] 3) The data redundancy of the process system is exacerbated. The data organization method of process card instantiation without abstraction determines that process data in this mode will continue to create and copy a large number of process cards with the increase of enterprise application time Data, unable to achieve effective accumulation and reuse of process data

This structured process design and data organization method solves the inflexibility of process file editing and distribution to a certain extent, but is still limited by the traditional process card file, and does not realize the structuring of design objects based on process planning However, in terms of creation and management of process data, combined packaging is still based on process files, which does not fundamentally solve the problem of management redundancy and upstream and downstream transfer of process data
