Analysis of Surface Defect Generation Mechanism in End Milling of UD-CFRP Based on Cutting Sound Analysis

Puntos clave

• To clarify the mechanism of surface defect generation during the end milling of UD-CFRP using cutting sound analysis.
• Investigated changes in cutting sound during defect generation in end milling of UD-CFRP.
• Examined the relationship between cutting conditions and surface defects.
• Analyzed distinct noises associated with defect occurrences.
• Identified that abnormal impulse noise occurs during defect generation.
• Observed that continuous abnormal sounds correspond to widespread surface defects.
• Highlighted the need for better cutting conditions to minimize defects.
