Research And Implementation Of Sheet Metal Parts Manufacturing Model’s Rapid Design Technology

Currently, as a connection between design and manufacture of metal sheet parts, manufacturing process information should be added in through the handwork of process designers. In the way of handwork,which can lead the tedious process, poor efficiency,bad veracity,directly influenced the development cycle of new aircraft. Focus on the problem above and the problem of lacking pertinence of three-dimension CAD software which guarantee its commonality, this paper developed the intelligentized,standardized and modularized design method through the research of metal sheet parts’manufacturing process information’fast modeling technology. Through this method, the design cycle has been cut down substantially and the quality of data source has been increased.Through the in-depth analysis and research on the three-dimensional design software CATIA, a platform for manufacturing model’s designing in enterprises, it can be concluded that through secondary development of the CATIA corresponding module, the manufacturing model’s fast and standardized design can come true.This paper has analysed and researched secondary development on CATIA detailedly, Summarised the way for CATIA secondary development, focused on the development based on CAA, showed the powerful features of CAA through examples.Based on the research on sheet metal parts manufacturing digifax design technology in digital manufacturing environment, process designers’experiences have be summarised and manufacturing data set design standard has been formed.Based on the summary of sheet metal parts’manufacturing process information, the general plan of sheet metal manufacturing data set fast design system has been completed. A series of fast design functions such as process auricle fast design,process allowance fast accession, two-dimension unwind data set have been developed.An easier and more humanistic interactive interface has been developed by using the powerful interactive design function of CAA.The accomplish of metal sheet manufacturing data set fast design system, laid a foundation to enterprise process design’s numeralization,adapted to heavy development effort of military and civil aircraft,cut down the cycle of process design and process preperation, had an important significance on the improvement of new aircraft development progress and quality.
