【摘要】 在机械产品中,标准件的尺寸是规定的离散数据,其参数化的实现不同于一般的零件。在这里,离散数据的参数化本质上就是变型设计。文中基于UG软件,提出了标准件参数化的两种实现方法,即由电子表格和表达式程序来实现,并对这两种方法的利弊作了比较。更多还原

【Abstract】 The sizes of standard units have been set. The ways for parameterized designing them are different from ways for else parts. Here, two simple methods will be introduced, based on UG software. By taking advantage of electronic tabulator and expression, it can be realized. Although both could be application widely, each one have two sides. Both advantages and disadvantages will be contrasted.更多还原
