Superficial Hardening in the Plane Grinding of AISI 1045 Steel

摘要

This work outlines the influence of cutting parameters on the superficial hardening of AISI 1045 steel during a grinding process. The parameters are infeed (d), workpiece velocity (v), and cross feed (s). Microstructural changes are also presented. A mathematical expression was obtained that relates the parameters to the maximum hardness obtained for a given cutting condition. No significant microstructure transformations were observed for any of the grinding conditions evaluated; however, changes in the superficial hardness were measured. It was found that when the studied cutting parameters increase, the superficial hardness increases.
