Abstract

According to the method for beauty degree calculation proposed by Ngo (2003), beauty degree calculation has been widely used in designing the shape of various objects and the aesthetics of various interfaces. He quantified the interface by dividing the interface into 14 indicators such as balance, symmetry, cohesion, and simplicity to achieve the objectification of beauty evaluation. This paper mainly studies the relationship between the interface aesthetic and the CNC machine tool evaluation by comparing the results of the machine tool's beauty degree calculation results and the participants' subjective evaluation scores, to verify the application of the beauty degree calculation on the evaluation of machine tool design, providing an idea for future machine tool design. First, 6 classic machine tool schemes were selected, and 8 related indicators were pre-processed through a questionnaire survey to obtain the 6 participating elements that the participants thought were most relevant to the appearance evaluation of the machine tool, to avoid subsequent elements interfering with the subjects' scoring. Then, 4 different types of machine tool were selected which can mainly represent the mainstream machine tool design, and the scores of 6 interface elements were calculated by MATLAB software to obtain the ranking. (https://www.mathworks.com/products/matlab.html) In the second step, the questionnaire was used to ask the subjects to rank the beauty of each machine tool design. Finally, the experimental beauty degree calculation results are compared with the subjective evaluation result. Compared subjective questionnaire result with the calculation results, the ranking of the calculation results is consistent. This shows that the beauty degree calculation results of the beauty of the machine tool are consistent with the subjective evaluation. The application of the beauty degree calculation in the evaluation of the CNC machine tool design scheme is scientific and accurate, which can realize the objective evaluation of the appearance of the machine tool and help the designers to improve the design scheme and design layout.

一种基于美观度计算的数控机床客观审美评价方法

根据Ngo(2003)提出的美度计算方法，美度计算已被广泛应用于各种物体的形状设计和各种界面的美学设计。他将界面量化，将界面分为平衡、对称、衔接、简洁等14个指标，实现美的客观评价。本文主要通过对比机床美观度计算结果与参与者主观评价分数的结果，研究界面美学与数控机床评价之间的关系，验证美观度计算在机床设计评价中的应用，为今后的机床设计提供思路。首先，选取6个经典机床方案，通过问卷调查对8个相关指标进行预处理，得到被试认为与机床外观评价最相关的6个参与要素，避免后续要素干扰被试的评分。然后，选取了4种主要能代表主流机床设计的不同类型的机床，通过MATLAB软件计算6个界面要素的得分，得出排名。(https://www.mathworks.com/products/matlab.html)第二步，采用问卷调查的方式，要求被试对每个机床设计的美观度进行排序。最后，将实验美度计算结果与主观评价结果进行比较。主观问卷调查结果与计算结果比较，计算结果的排序是一致的。这说明机床美观度计算结果与主观评价是一致的。美观度计算在数控机床设计方案评价中的应用科学、准确，可以实现对机床外观的客观评价，帮助设计人员改进设计方案和设计布局。
