一、概述在冲压生产中,排样工序占有非常重要的地位。由于冲压生产往往是大批量进行的,材料利用率方面微小的差异,可能引起金属耗用量的显著变化。因此,材料利用率的高低是评定一个排样方案优劣很重要的依据。采用电子计算机排样,能够克服手工排样的许多缺点,使材料利用率显著提高。据资料介绍,国外采用电子计算机排样后,材料利用率一般提高5～10％。本文研究单、双排冲裁的计算机排样辅助设计。编制了普通单排、对头单排、普通双排、对头双排冲裁时,确定最佳排样方案的程序,所有程序都是用FORTRAN语言编写 I. Overview In stamping production, the nesting process occupies a very important position. As stamping production is often done in large quantities, small differences in material utilization can cause significant changes in metal consumption. Therefore, the level of material utilization is to assess the merits of a nesting program is very important basis. The use of electronic computer layout, to overcome the many shortcomings of manual layout, material utilization significantly increased. According to the introduction of information, the foreign use of computerized layout, the material utilization generally increased by 5 to 10%. This article studies single and double row blanking computer aided design. The preparation of the ordinary single-row, the first single-row, ordinary double-row, double punching the right, to determine the best layout program procedures, all programs are written in FORTRAN language
