摘要：The article deals with the questions of the operating time calculation technique for the cutting PDC element of cylindrical shape. The results of laboratory studies of PDC plates in the accelerated material testing facility (AMT-2) are presented in the course of experimental studies, wear of the cutting elements over time, the relationship between the abrasiveness of the rock and the development of the PDC cutting element has been studied. The carried out researches allowed not only to confirm some existing experimental results, but also to propose a new dependence of PDC wear prediction in different rocks, rate of penetration and bit operating time in order to predict the rate of penetration. This largely determines the economic efficiency of the drilling process, greatly simplifying the forecasting of the bit wear.
