DRUG BIT CUTTING TRACE IMAGE COLOURS AND CUTTING FORCE FLUCTUATION RELATION

Rock cutting is developing area in mining and tunnelling sectors. In order to open anexcavation inside or surface of the rock masses, they should be dig up to obtain required engineeredvolume. Beside the conventional blasting methods result in total breakage of the selected parts of rockmasses, rock cutting machineries are used in some engineering projects which they have cutting bits totrim the rock masses into small chips. Drag bits, as a type, is one of the bit kinds which researchers haveanalysed for its design parameters for different rock masses. When rock bit cutting performances areunder consideration, laboratory cutting tests are performed and rocks are cut with different bit profilesto evaluate its design parameters. In these researches cutting traces have mostly been photographed fortest file data. It was realised here in this research and analyzed some of these images for their colourproperties. Different coloured sectors were determined along the selected cutting trace images whichwere compared also with the cutting force records of the related cutting tests. The colour distributionand colour difference areas of the trace images were then analysed with the cutting actions and rockmass features. The resultant enhanced coloured images and cutting forces fluctuation data obtainedduring cutting tests of drag bits showed that colour analysed can also be the indicators of cuttingperformance if they are carefully appraised.
