Final report
Publication metadata
Production sectors like automotive, mechanical engineering are faced strong competitive constraints from North America and Asia. To keep the European countries competitive, investigations in new research areas and innovation is essential. Integrated Computational Materials Engineering (ICME) is one of most attractive emerging discipline for research and innovation because it can accelerate materials development, unify design and manufacturing, help to create new technology area, and hence provide significant economic benefit. IMMAC project dealt with the use of innovative ICME-Tools in basic research for the machinability evaluation of ferrite-pearlite (FP) steels, including material modelling, cutting simulation and optimization. The objective of IMMAC project is to develop a numerical approach to better design the machinability-improved FP grade tailored to a given machining operation, and more broadly for a given application (type of components). The cutting operations studied are turning, drilling and broaching, mainly used in automotive or engineering components. To this end, a better understanding of thermal stress-strain behaviors, contact mechanisms and thermal properties of FP microstructures and material cutting tool have been achieved. The main parameters of FP microstructure driving the machinability performances were identified for each cutting operation. Moreover, an empirical formulation, only for the drilling, has been developed based on the microstructure parameters. Related model parameters identified through the rheological and tribological tests were used in numerical models to predict qualitative machinability performances of FP steels variants. With the help of numerical and empirical models, an optimized microstructure for crankshaft application could be predicted. Component oriented machining tests have confirmed this microstructure solution.
