Abstract (EN):
The results of an experimental study concerned with the evolution of cutting forces, tool wear and surface roughness, as functions of time when turning the particulate metal matrix composite A356/20/SiCp-T6 are presented, Inserts with polycrystalline diamond (PCD) were tested. Cutting forces were measured using a piezoelectric dynamometer. The wear type was identified and its evolution with cutting time was measured. To model the phenomena a hybrid technique based on an evolutionary search over the design space defined by the experimental results is considered. Optimal cutting conditions are searched using a genetic algorithm based on an elitist strategy. The chromosomes composed by random keys represent cutting conditions defined according to a temporal scale.
