由于在生产技术的最近的进展,太空系统设计者有许多更多的选择制作高质量的、低重量的、高能力的、划算的过滤器。除了象踩那样的传统的方法,钻并且 milling,由于他们处理能力增加,许多新途径广泛地在生产过滤器的惯例被使用了。然而,费用上的限制,对在更严格的条件例如下面学习的需要在好攻击的液体,在设计的同谋关系,材料的可使用性,和其它使从最新发达的过程选择一个令人满意的方法困难,例如,光化学的用机器制造(脉冲编码调制),相片 electroforming ( PEF )( LBM )并且激光横梁用机器制造过滤生产小、便宜、小太空。这篇文章估价帮助工程师选择最合适的途径生产太空过滤器的脉冲编码调制, PEF,和 LBM 的技术、节俭的生存能力。
Thanks to recent advances in manufacturing technology, aerospace system designers have many more options to fabricate high-quality, low-weight, high-capacity, cost-effective filters. Aside from traditional methods such as stamping, drilling and milling, many new approaches have been widely used in filter-manufacturing practices on account of their increased processing abilities. How- ever, the restrictions on costs, the need for studying under stricter conditions such as in aggressive fluids, the complicity in design, the workability of materials, and others have made it difficult to choose a satisfactory method from the newly developed processes, such as, photochemical machining (PCM), photo electroforming (PEF) and laser beam machining (LBM) to produce small, inexpensive, lightweight aerospace filters. This article appraises the technical and economical viability of PCM, PEF, and LBM to help engineers choose the fittest approach to turn out aerospace filters.
