Abstract
针对整体硬质合金刀具曲面结构复杂、参数化直接建模难以实现的问题,对整体硬质合金立铣刀的三维参数化直接建模进行了研究。分析了整体硬质合金立铣刀中包含的复杂曲线与曲面,将立铣刀的三维模型划分为5个重要特征,在三维建模过程中对每个特征根据刀具的设计规则进行了详细的数学建模,提取出了影响特征生成的关键几何设计参数,为每个特征建立了通用数学模型,通过ug/OPEn二次开发工具完成了立铣刀参数化界面设计,并在ug环境下建立了整体硬质合金刀具参数化设计系统。研究结果表明,整体硬质合金刀具参数化设计系统实现了复杂曲面刀具的参数化直接建模,节约了曲面方程的计算时间,有效提高了刀具设计与建模效率。
 
Aiming at realizing the direct modelingon solid carbide cutting tools with complex surface structure,the three-dimensional modeling of solid carbide end mills was researched.Complex curves and surfaces contained in the solid carbide end mills were analyzed, models of solid carbide end mills were divided into five features,each feature had detailed mathematical equation based on the tool designing rules during the modeling,the key geometric parameters influencing the feature generation were extracted,and each feature correspond to a general mathematical model.At last,the parametric interface design and parametric system of solid carbide cutting tools were built up by UG/Open secondary development tools.The results indicate that,the system completes the parametric direct modeling on solid carbide cutting tools with complex surfaces,saves the computing time of surface equation,improves the design and model efficiency of tools.
