立铣刀论文：整体硬质合金立铣刀CAD技术研究 【中文摘要】高速加工成为制造业主要发展趋势之一,在航空航天领域得到了广泛的应用,这对刀具设计提出了越来越高的要求。提高刀具性能、质量和可靠性,缩短设计周期,降低设计成本成了提高刀具企业竞争力的重要手段。将CAD技术与传统刀具设计技术相结合,建立整体硬质合金立铣刀的通用化三维设计平台,能够弥补传统设计方法上的一些不足,更好的满足设计要求。本文根据CAD建模需求的特点对整体硬质合金立铣刀进行了分类,归纳了整体立铣刀参数化建模所需参数间的几何拓扑关系,对不同种类的硬质合金立铣刀几何特征进行准确的数学描述,建立了适用于软件开发的整体立铣刀数学模型。针对刀具设计研究了已有刀具的重用、变形设计和全新刀具设计三个问题,对标准件库为基础的实例重用、KBE/UGKF技术和基于UG的二次开发技术这三部分内容进行了详细研究,建立了包含标准刀具库检索、KBE/UGKF技术建模和UG NX Open技术建模在内的整体立铣刀设计的集成方案,为系统的开发奠定了理论基础。利用开发工具Visual Studio 2008和SQL Server 2005,开发了基于UG的整体立铣刀三维设计软件系统。通过ADO.NET数据库连接技术,利用数据库软件的存储过程来完成复杂的数据处理过程,实现UG、软件系统与数据库的数据连接；应用KBE/UGKF技术,实现了硬质合金立铣刀的智能化设计；系统开发过程中应用了UG NX提供的NX Open技术,通过在微软的.NET中的C#中调用Common API,实现UG NX的二次开发,生成了动态链接库文件。通过软件系统,能够实现硬质合金立铣刀的实例检索、参数计算、辅助设计、三维建模、二维图生成以及加工仿真等功能。 【英文摘要】High-speed machining (HSM) plays an important role in modern Manufacturing Industry, which is widely used in aviation industry and so on. This leads to the strict quality requirements of tool design. It is a significant way to improve the competitive capacity of a company that developing the performance, reliability and quality of tools, shortening design period and lowering design cost. Based on the couple of the CAD technology and traditional tool design technology, a common 3D design platform of solid carbide end mills is generated in order to mix some gaps within the traditional design methods, as well as to meet the requirement in machine design.The solid carbide end mills are classified according to the characteristics of CAD modeling. Furthermore, the geometrical topological relations within the parameters used in solid carbide end mills parametric modeling are induced. The mathematical models which are suitable for software development have been established.A solution for the solid carbide end mills is proposed.
