摘要

1. A method comprising the steps of receiving performance data related to a cutting structure, calculating, using performance data, a characteristic curve related to the cutting structure, wherein the characteristic curve is constructed either based on weight or torque, and the characteristic curve is saved .2. The method according to claim 1, wherein the characteristic curve includes either weight on the cutting structure / rock strength or torque on the cutting structure / weight on the cutting structure as a function of penetration rate / rotation speed. The method of claim 1, wherein calculating the characteristic curve comprises the steps of: calculating the characteristic curve based on the weight, including the change in weight on the cutting structure as a function of the penetration rate of the cutting structure. The method according to claim 1, wherein the calculation of the characteristic curve comprises the steps of: calculating the characteristic curve based on the torque, including changing the torque on the cutting structure as a function of the penetration rate of the cutting structure. The method according to claim 1, wherein the calculation of the characteristic curve comprises the steps of calculating a characteristic curve based on weight, including a change in weight on the cutting structure as a function of the penetration rate of the cutting structure, and calculating a characteristic curve based on torque, including a change in torque torque on the cutting structure as a function of the penetration rate of the cutting structure. 6. The method according to claim 1, in which the calculation of the characteristic �
