摘　　要：自动优化套料可以提高材料利用率和排样效率,但是利用自动优化套料技术前必须首先对原始工艺数据进行预处理,其中拆分和组合是冲压加工中的基本工艺。针对板材件拆分和组合工艺需求,分析自动优化套料计算对数据预处理的要求,研究和提出拆分和组合工艺数据处理解决方案,设计和开发了工艺数据处理模块。该模块不仅提高了企业板材件工艺设计效率,为优化套料模块提供了准确数据,确保自动优化套料计算的可用性,而且为准确计算板材件材料定额提供了可行性。Automatic nesting optimization can improve the material utilizing rates and nesting efficiencies,but original designing data must be pre-processed,such as basic workpiece split/combination.Considering automatic nesting optimization,the requirements for sheet workpiece split/combination and requirements for data pre-processing were analyzed firstly.Then a solution for split/combination data pre-processing was proposed according to requirements above.As a result,the pre-processing module was developed and implemented.The efficiency of process designing was improved which provided accurate data for nesting optimization module,so that it becomes available to optimize nesting automatically and calculate material quota accurately.
