增材制造（AM）具有提高生产率的潜力，特别是加工时间、成本和表面粗糙度。在类似的生产线中，增材制造中基于装配的设计的零件分离可以帮助提高生产率。讨论了增材制造中基于装配的零件设计中零件分离的优化技术。该技术通过减少打印部件的处理时间来提高生产率，该处理时间是构建时间和装配时间的总和。该技术使用最佳切割平面进行零件分离，与随机切割平面相比具有明显的优势。这项工作讨论了遗传算法（GA）技术的部分分离使用平面切割。优化技术提供了最佳数量的零件组装和其相应的构建方向的最短的处理时间。通过三个算例说明了该方法的应用。最后，从两个例子的结果进行了比较，已经建立的爬山优化方法的部分分离。
Additive manufacturing (AM) has the potential to improve productivity especially processing time, cost and surface roughness. In similar lines, part separation for assembly-based design in additive manufacturing can help in improving productivity. This paper discusses an optimization technique for part separation in assembly based part design in additive manufacturing. The technique improves the productivity by decreasing the processing time of printed parts, which is the sum of the build time and the assembly time. The technique uses optimal cutting planes for part separation that has distinct advantages compared to random cutting planes. The work discusses a Genetic Algorithm (GA) technique for part separation using planar cuts. The optimization technique provides the optimal number of parts for assembly and their corresponding build orientations for the minimum processing time. Three examples have been provided to demonstrate the application of the proposed method. Finally, the results from two examples are compared to the already established hill climbing optimization method for part separation.
