Part orientation is a critical task in the process of additive manufacturing product realisation. Recently, various computer-aided methods for this task have been presented in the literature. The coexistence of different methods generates a series of questions: What are the common characteristics of these methods? What are the specific characteristics of each method? What are the main issues in computer-aided part orientation for additive manufacturing currently? What are the potential research directions in this field in the future? To approach these questions, a review of the existing computer-aided part orientation methods for additive manufacturing is presented in this paper. This review starts with a clarification of a part orientation problem and a classification of the existing methods into two categories according to their process of solving the problem. An overview of the representative methods in each category is then carried out from the aspects of approaches for orientation search, generation, or selection, estimation of build orientation factors, determination of weights of factors, establishment of overall objective function, and demonstration of effectiveness. After that, a discussion about the main issues in computer-aided part orientation for additive manufacturing is documented based on the overview. Finally, a suggestion of some future research directions in this field is reported.

增材制造的计算机辅助零件定向的现状,问题和未来

零件定向是增材制造产品实现过程中的关键任务。最近,文献中已经提出了用于该任务的各种计算机辅助方法。不同方法的共存产生了一系列问题:这些方法的共同特征是什么?每种方法的具体特点是什么?当前用于增材制造的计算机辅助零件方向的主要问题是什么?未来该领域的潜在研究方向是什么?为了解决这些问题,本文介绍了现有的用于增材制造的计算机辅助零件定向方法。本文首先从零件定位问题的澄清开始,然后根据解决问题的方法将现有方法分为两类。然后,从定向搜索,生成或选择的方法,构建定向因子的估计,因子权重的确定,总体目标函数的建立以及有效性的证明等方面对每种类别中的代表性方法进行了概述。之后,基于概述记录了有关增材制造的计算机辅助零件定向中主要问题的讨论。最后,报告了对该领域一些未来研究方向的建议。然后,从定向搜索,生成或选择的方法,构建定向因子的估计,因子权重的确定,总体目标函数的建立以及有效性的证明等方面对每种类别中的代表性方法进行了概述。之后,基于概述记录了有关增材制造的计算机辅助零件定向中主要问题的讨论。最后,报告了对该领域一些未来研究方向的建议。然后,从定向搜索,生成或选择的方法,构建定向因子的估计,因子权重的确定,总体目标函数的建立以及有效性的证明等方面对每种类别中的代表性方法进行了概述。之后,基于概述记录了有关增材制造的计算机辅助零件定向中主要问题的讨论。最后,报告了对该领域一些未来研究方向的建议。在概述的基础上,对增材制造的计算机辅助零件定向中的主要问题进行了讨论。最后,报告了对该领域一些未来研究方向的建议。在概述的基础上,对增材制造的计算机辅助零件定向中的主要问题进行了讨论。最后,报告了对该领域一些未来研究方向的建议。
