通过在单个工作站内协同结合加法和减法过程，可以利用每个过程的相对优点。这有利于制造具有理想几何精度和表面特性的内部，悬垂和高纵横比特征。加工、测量和再加工材料的能力使损坏的高价值部件能够再生和修复。这些技术为提高功能性零件的材料利用率、零件复杂性和质量管理提供了重要的机会。用于混合加减法工艺（whasp）的单平台工作站的数量正在增加。其中许多集成了加法定向能沉积（DED）与减法数控加工在一个高度移动的多轴机床。先进的数字控制（NC）和计算机辅助设计（CAD）、制造（CAM）和检验（CAI）有助于控制这一过程。本研究回顾并批判性地讨论了与whasp发展相关的重要出版文献，并确定了未来的研究和发展途径。它报告了最先进的WHASP系统，确定了关键特征和研究差距。最后，根据该研究领域的新兴趋势和未来机会，提出了whasp和其他混合机床的未来愿景。(C) 2015 Elsevier Ltd.版权所有。
By synergistically combining additive and subtractive processes within a single workstation, the relative merits of each process may be harnessed. This facilitates the manufacture of internal, overhanging and high aspect ratio features with desirable geometric accuracy and surface characteristics. The ability to work, measure and then rework material enables the reincarnation and repair of damaged, high-value components. These techniques present significant opportunities to improve material utilisation, part complexity and quality management in functional parts.The number of single platform workstations for hybrid additive and subtractive processes (WHASPs) is increasing. Many of these integrate additive directed energy deposition (DED) with subtractive CNC machining within a highly mobile multi-axis machine tool. Advanced numerical control (NC), and computer aided design (CAD), manufacture (CAM) and inspection (CAI) help to govern the process.This research reviews and critically discusses salient published literature relating to the development of WHASPs, and identifies future avenues for research and development. It reports on state-of-the-art WHASP systems, identifying key traits and research gaps. Finally, a future vision for WHASPs and other hybrid machine tools is presented based upon emerging trends and future opportunities within this research area. (C) 2015 Elsevier Ltd.
