摘要: 现阶段,尖端装备对高精密复杂微型结构件的需求越来越大,微铣刀的专用化需求挑战着刀具设计的灵活性和准确性。目前,微铣刀设计领域存在以下问题:由于尺度差异导致传统铣刀设计方法已不再适用、切削工艺优化过程与刀具设计过程相分离。针对以上问题开展了微铣刀设计方法的研究,并开发了微铣刀参数化设计系统。首先基于UG/Open平台建立了微铣刀三维模型样板文件并对其几何特征进行解构,通过表达式功能串联刀具几何特征,借助程序编程实现驱动,完成微铣刀三维模型的快速设计;最终基于UG二次开发平台,以加工需求为驱动,以工件材料、加工结构、加工工艺等多种因素限制为约束条件,通过刀具设计特征,将刀具的设计参数与切削效果结合起来,开发了微铣刀参数化设计系统。

Abstract: At present, the demand for sophisticated equipment for high precision and complex micro structural parts is increasing. The need for specialize in micro-mills challenges the flexibility and accuracy of tool design. The following problems exist in the field of micro-mills design:The design method for traditional milling cutter is no longer applicable because of scale difference, and the optimization of cutting process is separated from the tool design process. Aiming at the above problems, studying the new design method of micro-mills and develops the design system of it. Based on UG/Open, the 3D model template of the micro-mills is established and its geometric features are deconstructed. Through expression function, the geometric features of the tools are connected in series, and then driven by program programming. Finally, based on the UG secondary development platform, the system is driven by the processing needs, with the workpiece material, processing technology and other factors as the constraint conditions, through the tool geometric characteristics, the tool design parameters and cutting effect combined, and finally developed the parametric design system of micro-mills.

Key words: micro-mills, parametric design system, optimization of geometrical parameters, UG secondary development
