Immersive visualization technologies have been the subject of a significant amount of research in the engineering and manufacturing communities. As a result, various tools have been developed to support a wide range of processes throughout the lifecycle of a product, such as design, review, process planning, manufacturing, inspection, training, maintenance, and remote assistance. However, the impact of these technologies on process planning activities has received comparatively less attention. In this paper, we examine current advances in immersive visualization technologies in the field of Computer-Aided Process Planning (CAPP) and identify current challenges, future directions, and research gaps. CAPP is studied through the lens of Product Lifecycle Management (PLM) to propose a series of design guidelines for the development of VR-based immersive CAPP technology. The primary conclusion of the review is that although immersive visualization technologies can improve various process planning scenarios, such as decision-making and real-time response support, verification, training, and automatic generation of process plans, many challenges such as data interoperability, unidirectional 3D data flows, and operation accuracy from technology, process, and organization aspects remain to be addressed.

沉浸式可视化技术已成为工程和制造社区大量研究的主题。因此，开发了各种工具来支持产品整个生命周期中的各种流程，例如设计、审查、流程规划、制造、检查、培训、维护和远程协助。然而，这些技术对流程规划活动的影响相对较少受到关注。在本文中，我们研究了计算机辅助过程规划 (CAPP) 领域沉浸式可视化技术的当前进展，并确定了当前的挑战、未来的方向和研究差距。通过产品生命周期管理（PLM）的视角研究CAPP，为基于VR的沉浸式CAPP技术的发展提出一系列设计指南。审查的主要结论是，虽然沉浸式可视化技术可以改善各种工艺规划场景，如决策和实时响应支持、验证、培训和工艺方案的自动生成，但数据互操作性、单向性等诸多挑战。技术、流程和组织方面的 3D 数据流和操作准确性仍有待解决。
