Abstract
The grinding process is widely used to improve the parts machined accuracy by other manufacturing processes and heat treated. The grinding process result depends on the cutting conditions, which incorrectly selected, can cause microstructural changes that prevent the use of the machined component. In addition, there is a lack of information about grinding damages in carbon steels due to the high costs of non-destructive methodologies for checking microstructural changes, such as the Barkhausen noise (BN). The AISI 1020 steel has plasticity and excellent weldability and is widely used in the mechanical industry. The aim of this work is to analyze normalizing heat treatment influence and the surface grinding on AISI 1020 steel grinding process results. Different grinding process conditions and a conventional grinding wheel were used in the AISI 1020 steel surface grinding. BN was measured in all samples, varying magnetic excitation frequencies of 10 Hz and 50 Hz. The roughness and hardness machined samples evaluations complement the study. An inverse relationship between normalizing heat treatment and BN results was observed.
