根据冒口设计的基本理论,基于SINOVATION三维造型软件源代码,分别利用Visual Studio2005、MicrosoftAccess2003进行用户交互界面的设计和标准冒口数据库的建立,结合SINOVATION软件自带的Script语言进行了基于三维实体的铸铁件冒口CAD模块的开发。该模块覆盖了《铸造手册》中铸铁件的15种标准冒口图形,同时各项参数均可尺寸驱动任意修改。经测试,该冒口CAD模块界面友好,功能稳定,能够提高铸铁件冒口设计的精度和效率。 According to the basic theory of riser design, based on SINOVATION three-dimensional modeling software source code, the design of user interface and the establishment of standard riser database are respectively carried out by using Visual Studio2005 and MicrosoftAccess2003. Based on the script language of SINOVATION software, Development of Cast Iron Riser CAD Module. This module covers 15 standard riser graphics of cast iron in the Casting Manual, with all parameters dimensionally adjustable. After testing, the riser CAD module friendly interface, function and stability, can improve the accuracy and efficiency of the design of cast iron riser.
