采用不同布齿方式的3个PDC切削齿同步连续切削转动的岩石来模拟井底钻头切削齿实际工作状态,用切削岩石时相同的布齿参数切削砂轮来磨损切削齿以模拟切削齿磨损状态,试验研究了不同磨损程度的切削齿受力与布齿密度的关系。
Three PDC cutters with different cloth teeth were used to simulate the actual working state of cutting bit by synchronously cutting the rotating rock. The same cutting parameters were used to cut the grinding wheel to wear the cutting tooth to simulate the wear state of the cutting tooth. The relationship between cutting force and cloth densities under different degrees of wear was studied experimentally.
