研究了钣金数控冲切加工中零件信息模型的建立、自动优化排样、冲切工艺处理和NC代码生成。
Study the set up of information module of parts in NC blanking process of sheet metal, auto optimized layout, blanking process handling and NC code generating.
板材排样优化的核心问题是规划零件在板型原材料上最佳的下料组合与每个下料零件在板材上的最优布局方案。
The kernel of this problem is to programming the best nesting combination and the best composition scheme of each part on the blank sheet.
同时，自动排样系统产生的排样图还可以通过零件之间互换位置，零件的旋转、移动等方式来对局部实现优化。
Meanwhile, the nesting map produced by the automatic nesting system may be locally optimized through changing the mutual positions of the parts, or revolving and moving the parts.
本算法适合应用于大批量、多种类的矩形零件在定宽无限长板材上的优化排样，获得了较好的优化排样方案；
This algorithm is suitable for optimized layout of rectangle parts with large amounts and many kinds and better optimized layout is got.
