EFFECT OF HIGHER TEMPERATURE ON THE COEFFICIENT OF FRICTION IN SHEET METAL FORMING
Original language description
The coefficient of friction (COF) plays a critical role in determining the material flow, surface quality, and tool wear in sheet metal forming processes. This study investigates the effect of elevated temperatures on the COF between commonly used sheet metals and forming tools. Experimental tests were conducted under controlled conditions to assess the frictional behaviour at varying temperatures, simulating industrial thermo-mechanical environments. Results reveal that as temperature increases, the COF exhibits significant variation, influenced by factors such as material softening, lubrication performance, and oxide layer formation. Higher temperatures generally lead to a reduction in the COF due to enhanced lubrication dynamics and material ductility. However, in certain cases, degradation of lubricant properties and increased adhesion at the tool-metal interface cause a rise in COF. The findings underscore the importance of temperature management and lubricant selection in optimizing sheet metal forming processes for improved efficiency and product quality.
