contour lines. Contour Lines are curves that connect points of equal elevation. Each contour line on a map has a number that represents the elevation of the line (usually the height above sea level). The Contour Interval is the change in elevation between two contour lines. If the contour interval of the map below is 20 meters, how high is Wildcat

ELID GRINDING PDF - sudprof.com

The simulation result shows that, the uniform height of the abrasives in the contour of the grinding wheel is grinsing owing to the existence of passivation film in ELID grinding, it is related to the thickness of the passivation film, and processing quality in ELID grinding could be enhanced through controlling of thickness of the passivation film.
