摘要：整体式立铣刀作为铣刀当中比较典型的一类，实际上在它的圆周以及底部当中都含有一种切削刃，是非常经典的柄式刀具，可进行侧面、平面、槽以及型面的铣削加工。整体式立铣刀具有空间结构复杂，尺寸繁多的特点，而其中一些关键结构，例如刃数、螺旋角、槽型、周刃前角、周刃后角等对于切削性能的影响较大。如果设计者只需要提供刀具的结构参数，根本不必制造出原型产品，就能在计算机中实现对刀具的三维建模、二维图纸生成以及切削仿真等一系列工作，那么刀具的设计效率以及研发成本是否大大降低了呢？而现在，借助于刀具的参数化设计技术，采用“参数化设计-加工仿真”的模式就可以实现这一工作。因此，对刀具参数化设计软件系统的研究具有非常重要的意义。学习UG二次开发的各种工具，了解了每种工具的特点和适用范围之后。选择UG/Open API编程语言，结合使用UG/Open MenuScript和UG/Open UI Styler开发工具，实现了基于UG二次开发整体式立铣刀的三维参数化快速造型设计。

Abstract：The integral end mill is a kind of milling cutter, which is a kind of cutting tool with cutting edge at the circumference and the bottom, which can be used for milling of side, plane, groove and profile.Integral end mill space structure is complex, size. The influence of the key structure such as blade number, groove type, helix angle, front blade front angle and rear edge angle has great influence on cutting performance. With the help of tool parametric design technology, the use of parametric design processing simulation "mode, the designer needs to provide the tool structure parameters, do not have to create a prototype product, you can achieve in the computer tool modeling, Cutting simulation and a series of work, greatly reducing the cost of tool research and development, improve the efficiency of the tool design and tool manufacturing enterprises competitiveness.Therefore, it is very important to study the parametric design software system of tool.Learning UG secondary development of the various tools to understand the characteristics of various tools and the scope of application.The UG/Open API programming language was selected to combine the UG/Open Menu Script and UG/Open UI Styler development tools to realize the three-dimensional parametric rapid modeling design of the integrated end mill based on the UG secondary development tool.
Keywords: End mill; parametric design; chip flute; UG secondary development
