DAMAGE INDUCED IN A SMOOTH WORK PIECE OF A SLIDING DIAMOND- AN APPROACH TO HARD ROCK DRILLING

OPTICAL METHODS WERE USED TO EVALUATE THE EARLY STAGES OF DAMAGE CAUSED BY A LOADED SPHERICAL DIAMOND MOVING OVER A SMOOTH SURFACE, AS A FUNCTION OF SPEED, RADIUS, LOAD AND LUBRICATION, FOR SEVERAL HOMOGENOUS MATERIALS. NEW TYPES OF CRACKING PATTERNS AND ABRADED TRACKS HAVE BEEN OBSERVED. THE STATISTICAL VARIATION FROM TRACK TO TRACK, AND EVEN WITHIN ONE TRACK, IS SO GREAT THAT QUANTITATIVE CONCLUSIONS ARE NOT POSSIBLE AT THIS STAGE, ALTHOUGH SOME GENERAL EFFECTS OF THE VARIABLES ARE NOTED. APPLICATION TO HARD ROCK DRILLING IS NOT STRAIGHTFORWARD AND WILL PROBABLY HAVE TO AWAIT AN EVALUATION OF MATERIAL REMOVED. /AUTHOR/
