摘要
为解决儿童实木家具零部件存在的多样化问题,利用成组技术对零部件进行标准化试验。选取20件儿童家具,零部件共1 084个,其中实木零部件共705个,通过加工相似性原理,取零件的3个关键结构特征进行分析,包括:零件长边方向中心线、长边方向外表面形状、短边方向外表面形状,依据工艺相似性,对零件进行分类;据此建立儿童家具零件族,并对零件族中零部件分布情况进行分析,将尺寸相差在2 mm内的零部件合并、尺寸值以合并前零件数量较多的为主,且向原规格或其1/2靠拢的方法对零件规格尺寸进行优化设计。结果为厚度规格种类减少了20种,宽度规格种类减少了12种,从而提高儿童家具的生产效率,降低生产成本,缩短研发周期。
With the rapid physical and mental development of children,their demand for furniture style,function and structure will change correspondingly. Therefore,furniture makers need to response rapidly to market demands,which brings great pressure on the production process because workers have to frequently adjust machine and cutting tool parameters. This study aims to solve the standardization problem in children＇s solid wood furniture parts. The group technology was applied and 20 pieces of the children ＇s furniture containing 1 084 components and parts were selected.Through the similarity processing principle,we analyzed the structural characteristics of 705 solid wood parts.Besides,three key structural characteristics of these parts were analyzed,including center line of the long side,outside surface shape of the long side and outside surface shape of short side. Based on the analyzed results,the parts were classified by using machining similarity,and six part groups were established,including square parts group,interchangeable parts group,linear configuration parts group,curve configuration parts group,cylindrical parts group and wood-based panel parts group. The parts distribution in each part group was also analyzed. The sizes of the furniture parts were optimized by incorporating parts with size difference of less than 2 mm. That made the number of the thickness and width sizes reduced by 20 and 12,respectively. Based on the results of this study,furniture makers can implement mass customization production and rapid response to market demands through advanced manufacturing technologies such as flexible manufacturing system,just-in-time manufacturing,enterprise resource planning. Just in that way,we improved the production efficiency,reduced the production cost and shortened the development time for children＇s furniture.
