CUTTING ROCK WITH WATER JETS

CUTTING TESTS WERE MADE WITH CONTINUOUS HIGH PRESSURE WATER JETS ON THREE REPRESENTATIVE TYPES OF ROCK TO OBTAIN COMPREHENSIVE DATA SUITABLE FOR EXPLORING BASIC JET-CUTTING RELATIONSHIPS. TEST MATERIALS WERE BEREA SANDSTONE, INDIANA LIMESTONE AND BARRE GRANITE, FOR WHICH GENERAL PROPERTIES HAVE BEEN FULLY DETERMINED. NOZZLE PRESSURES RANGED FROM 1000 TO 60,000 LBF/IN2, TRAVERSE SPEEDS WERE IN THE RANGE 0.002-5.5FT/SEC, AND NOZZLE DIAMETERS WERE FROM 0.008 TO 0.015 IN. DIMENSIONS OF SLOTS CUT NORMALLY INTO THE SURFACES OF THICK BLOCKS WERE MEASURED, AND SPECIFIC ENERGY VALUES WERE CALCULATED. COMPLETE RESULTS ARE GIVEN IN BOTH TABULAR AND GRAPHICAL FORMS.(A)
