Key Points

The aim is to propose an integrated evaluation framework that correlates emotional assessment and manufacturing performance of product edge geometries.
Conducted emotional assessment experiments using a 7-point Likert scale with 80 adults aged 20-30.
Performed CAE-based CFD simulations on three edge shapes: right angle, inclined, and curved.
Applied factor and ANOVA analysis to verify emotional differences and conducted correlation analysis on standardized indices.
Significant differences were found in emotional perception and manufacturing performance across edge geometries.
Curved shapes exhibited the highest emotional evaluation and flow stability.
A strong positive correlation was confirmed between emotional assessment and manufacturing performance indicators.
