How to Read a Topographical Map - USDA
Common contour intervals are 5, 10, 20, 40, 80, or 100 feet. The actual contour interval of a map depends upon the topography being represented as well as the scale of the map. If you look at the areas marked with an orange box on this map you will see contour elevation numbers. This is the elevation of the contour line, relative to mean sea level.

Materials | Free Full-Text | Effects of Grinding Passes ...
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.

It is well known that the rail grinding burn is significantly affected by the grinding temperature. In this study, a three-dimensional contour map of maximum rail grinding temperature under different rotational speed and grinding pressure conditions is established and given in Fig. 18. With the aid of this grinding temperature mapping, it is ...

Ductile-regime grinding is a new technology made possible by the use of real-time control and precision engineering in the grinding process. By ensuring that the abrasive grinding forces do not exceed a threshold value, it is possible to grind materials that are normally considered "brittle" in such a way that the material removal takes place through plastic deformation rather than fracture.
