【摘要】 铸造工艺CAD的研究日趋广泛,国内外对数值模拟的研究已有许多报道。但铸造工艺CAD中关于几何模拟的研究却较少,而几何模拟在铸造工艺CAD中占有重要地位,是铸造工艺CAD走向实用的不可缺少的一环。本文针对尚未解决的铸件图的识别和绘制问题,介绍了作者提出的铸造工艺图的“动态特征”绘图方法以及实现的具体步骤和应用实例。更多还原

【Abstract】 Study in casting technological CAD is widespread day by day. There have been a number of studies and reports about digital-simulation at home and abroad. But study in geometry-simulation in casting technological CAD is still little. However, geometry-simulation in casting technological CAD occupies am important position, and is an essential link in making casting technological CAD trended to practicality. This thesis is directed against unsolved problem in understanding and drawing of the layout of casting. A "dynamic-features" drawing method of casting technological graph is put forward by authors, its particular realizing steps and some applying examples are introduced as Well.更多还原
