Minimal Quantity Lubrication in Progressive Die Stamping

This paper presents a sustainable approach to utilizing oil lubricants in progressive die stamping for small components, aiming to reduce environmental impact while maintaining product quality. Numerical analysis explored the sensitivity of stamping operations to friction variations. Experimental tribological tests compared conventional lubrication practices with Minimal Quantity Lubrication (MQL), which applies less than 1 g/m2 of oil. Results showed MQL increased friction slightly but maintained acceptable product quality. These findings highlight the need to optimize MQL parameters for stable performance in industrial stamping processes.
