面向数控车间的刀具需求计划制定方法研究

Research on the Method of Making NC Workshop Oriented Tool Requirement Planning

刀具需求计划是刀具管理系统中研究的重点,也是企业管理所关心的焦点。文章提出了一种针对数控模块化刀具的刀具需求计划制定的计算方案,该方案考虑到模块化刀具中不同模块由于磨损方式不同,从而导致换刀节奏和需求量的不同,针对不同模块分别制定了相应模块的需求计划计算方案。同时,考虑到切削刀具模块的库存是具有生命库存特征的自消化性库存,在计算最终刀具物料采购计划时使得结果更加符合实际情况。基于此方案开发的刀具管理系统具有较好的适应性,对于企业的刀具准备工作及采购计划制定具有较好的指导作用。

Cutting tool requirements planning is the key research to cutting tool management system, is also the focus of enterprise management. This paper presents a computational scheme for the tool requirement planning of NC modular tool, the scheme takes into account the different modules for wearing in different ways, resulting in the difference of tool changing rhythm and demand, and according to different module re-spectively formulate the different calculation scheme for corresponding module demand plan. At the same time, considering the cutting tool module inventory is the self digestive inventory with life inventory charac-teristics, when calculating the final cutting tool material procurement plan makes the results more in line with the actual situation. Based on this solution developed a tool management system has good adaptability and has good guidance for the tools preparation and purchasing plan of the enterprise.
