| This paper is based on the topics described in double curvature of the wider use of sheet metal on the basis of integration with AutoCAD software VB sheet metal parts in the secondary development of technology, sheet metal double curvature of the secondary development were analyzed and discussed, and light of the actual conditions encountered in the production of iron and steel converter design problems, the CAD has been developed based on double curvature of the transition of the sheet metal started applications.From Bo ship Heavy limited liability company in the project in the process of cooperation in the technical aspects of the status quo as a starting point, through the investigation, analysis, feasibility studies, compared with secondary development of the AutoCAD functions, features, as well as in industrial production in the broad application of on the five CAD development tools for analysis, the combination of its own software development and the characteristics of the selected use of Visual Basic and AutoCAD software platform for the development of solutions in the design of steel converter start design issue and the realization of a dual-curvature of the sheet metal transition of the start. The software is characterized by the existence simple, so that engineers can combine the actual production of the actual need, intuitive, clear and easy to configure the product specific numerical parameters. Thereby increasing productivity and saving time.This paper mainly discusses the double curvature sheet metal CAD system and start system design method. Sheet metal started calculation and automatic generation Sheet Metal Parts map is very practical. For sheet metal nesting provide some problem-solving ideas and methods. At present these methods have been applied to the development of the CAD system started. The system is easy to operate and powerful, high universality, scalability, and the popularization and application of a higher value. |
