微小型零件切断装置优化设计分析

Optimization Design of Micro-part Cutting Device

为了提高零件的加工效率与加工质量,加工过程中应尽量避免再次装夹。本文采用慢走丝电火花线切割技术设计(一种新型装置),在五轴数控铣床上实现了对微小型零件自动化切断加工。在设计过程中,采用Genetic Aggregation响应曲面法,结合多目标遗传算法对固定板结构进行多目标优化,使微小型零件切断装置具有固有频率,丝架达到最大变形,X2滑台最大变形达到最优。

In order to improve the processing efficiency of parts and quality, the process should try its best to avoid reclamping. In this paper,a new type of device is designed by cutting wire EDM technology. The miniature parts are cut off on the five-axis CNC milling machine. During the design process the genetic algorithm was used to optimize the structure of the fixed plate structure, and the natural frequency of the micro-part cutting device and the maximum deformation of the wire frame were optimized. The maximum deformation of the X2 slide was optimized.
