Abstract

The invention discloses a pipeline welding process batch planning system and method based on characteristics. The method comprises the following steps of Firstly creating a product structure accordingto tasks and descriptions; performing Product structure version, STATE, EFFICIENCY MANAGEMENT, extracting manufacturing characteristics and then associating with a product structure; selecting a product structure according to the current task to create a pipeline welding process; executing the batch creation of the pipeline welding process; planning the process content of each pipeline welding process; specific process contents are further completed; a numerical control pipe bending procedure is integrated for a pipeline welding process; The method comprises the following steps of: directly extracting manufacturing characteristics as project contents of actual measurement records in an output actual measurement record chart according to related process contents, pipeline manufacturing characteristics and a corresponding relation between the pipelines and welding seams in pipeline welding processes as required, and finally, carrying out approval control on the pipeline welding processes and carrying out version control on the processes related to the pipelines.

Description

technical field [0001] The invention relates to the technical field of digital manufacturing, in particular to a feature-based pipeline welding process batch planning system and method. Background technique [0002] Spacecraft development tasks are increasing day by day, facing a new stage of multi-model simultaneous development, multi-task parallelism, and high-density launch. Typical product pipelines of spacecraft have different uses in different systems, such as propulsion systems, thermal control systems, environmental control and life protection systems, etc. The multi-purpose of the pipeline also determines its characteristics of small shape, large quantity, high precision and high welding quality requirements, which is the bottleneck restricting the efficiency of spacecraft development. [0003] The spacecraft pipeline welding process batch planning system takes pipelines as the design object, and aims to improve the automation of pipeline welding process design and...
