Material Modeling and Experimental Study of Serrated Chip Morphology



T Mabrouki, Laurent Deshayes, J F. Rigal, Kevin K. Jurrens, Robert W. Ivester


Machining chip morphology stems from mechanical, thermal, and chemical phenomena. Chip morphology      prediction depends on a fundamental understanding of these phenomena and is industrially important for cutting force prediction and surface integrity control. Our paper focuses on modeling errated-chip formation through comparison of thermo-mechanical simulations of cutting processes to experimental observations. The simulations utilize plasticity and damage models to predict chip morphology. The major points treated in this paper concern physical phenomena accompanying serrated-chip formation with variation of feed. Experimental analysis of chip morphology supports simulation results for various cutting parameters and American Iron and Steel Institute (AISI) 4340 steel.
