Materials
A three dimensional finite element model of rail grinding was established to explore the effects of grinding passes and grinding direction on the material removal behaviour of grinding rails during the grinding process The results indicate that as the number of grinding passes increases a decrease in the grinding force reduces both the amount of removed rail material and the surface roughness.
