Abstract
This article describes the experimental and simulation analysis of vertical surface grinding process. The grinding experimental under different conditions such as cutting speed, workpiece speed and depth of cut (vs, vw e ap). The prediction simulation of grinding forces involved in the process has been evaluated by finite element model (FEM). Reduced contact points between abrasive grain and workpiece in the dry condition were used in both the experimental test and the simulation. The objective is to determine the forces per grain and estimate the forces of conventional Al2O3 straight cup wheels in industrial operations. The material investigated has no specific data regarding numerical simulation, this material is mold and die steel produced by Villares metals called N2711M. The results showed the behavior of two forces orthogonal to each other that are directly related to chip formation and give an idea of the energy involved in the process. The effects of deformation in relation to the passage of grains over the surface provide information about the behavior of the investigated material in relation to surface quality aspects presented through the images extracted from scanning electron microscopy observations. The results indicates that there is a good agreement between the experimental and simulated results, as the coefficients of the constitutive law model of the material were determined. The most influential parameters on the force results are the cutting speed and depth of cut. The feed demonstrated how the passage of abrasive grains deforms the surface of the workpiece, resulting in a good method for tribological analysis of the contact between abrasive and workpiece. In the future, the expectation is to develop grinding wheels with orientation in the distribution of abrasive grains to reduce costs in their manufacturing, improving the material removal rate of the workpiece, and the produce finished surfaces with lower energy consumption.
