FMS刀具准备系统研究

Study on Tool Preparing System for FMS

围绕刀具准备系统的研究与开发 ,论述了刀具准备系统的总体结构和刀具寿命管理、刀具贮备管理、GT概念下刀具分配策略三个功能模块 ,利用相对磨损率来衡量刀具的磨损程度 ,从而对刀具寿命进行优化 ;根据从 MRP和 MPS得到的信息以及刀具的使用数据 ,生成基于成本优化的刀具补充策略 ;并将成组技术、遗传算法及虚拟刀具库思想 ,应用于刀具分配 ,解决FMS中刀具的优化分配问题。

This paper deals with the research and development of tool preparing system. An architecture of tool preparing system for FMS is proposed. At the same time, the function analysis of the tool preparing system is discussed in detail. A new concept, tool relative wear ratio, is proposed to measure tool-wear accurately. This paper constructs a dynamic tool requirement planning for optimizing FMS tool inventory based on information from MRP and MPS.. A new tool allocation strategy integrating group technology, genetic algorithms and virtual tool matrix strategy, it can solve the problem tool allocation and its optimization.
