目的 为了解决机床防护外观设计过程中工业设计与工程的感性认知协同问题，更好地寻求和增强双方对机床外观的认知共识，提高设计的效率和明确性，进而提高我国机床产业的整体竞争力。方法 将扎根理论的定性研究与感性工学的定量研究相结合，首先通过扎根理论聚类并提炼工业设计与工程领域存在共识的感性意向词汇;然后，使用语义差异法对代表性样本进行影响因子和造型特征元素分析，明确双方可协同的机床设计元素与感性认知的映射关系;最后，基于相应具体案例需求进行设计实践。结论 明确了机床外观设计过程中关于工业设计和工程双方存在协同认知的若干影响因子及其对应的典型感性词汇，构建了面向机床防护外观设计流程的ID&E感性认知协同系统，为机床外观设计领域提供有效的方法参考和优化思路。

The work aims to solve the problem of perceptual cognition collaboration between industrial design and engineering in the process of machine tool protection appearance design to better seek and enhance the consensus cognition of both sides on the machine tool appearance and improve the efficiency and clarity of the design, thus improving the overall competitiveness of China's machine tool industry. The qualitative research of grounded theory was combined with the quantitative research of Kansei engineering. Firstly, the grounded theory was used to cluster and extract the common perceptual image words in the field of industrial design and engineering. Then, the semantic difference method was used to analyze the impact factors and modeling feature elements of the representative samples, and the mapping relationship between the machine tool design elements and perceptual cognition that could be coordinated by both sides was clarified. Finally, design practice was carried out based on the corresponding specific case requirements. Several influencing factors and corresponding typical perceptual terms of collaborative cognition between industrial design and engineering in the process of machine tool appearance design are defined, and ID&E perceptual cognition collaborative system for machine tool protection appearance design process is constructed, which provides effective method reference and optimization ideas for the field of machine tool appearance design.
