提出了一种预测高速钻井中推力和扭矩的新理论模型。该方法包括确定沿着麻花钻的唇部和横刃的推力和扭矩的连续分布。计算中，远唇部采用斜切削模型，横刃采用正交切削模型。推力和扭矩是根据钻头的几何特征、切削条件和被加工材料的特性获得的。 (C) 1998 年由爱思唯尔科学有限公司出版。保留所有权利。
A new theoretical model to predict thrust and torque in high speed drilling is presented. The method consists of determining the continuous distributions of thrust and torque along the lip and the chisel edge of a twist drill. The calculation uses the oblique cutting model far the lip and the orthogonal cutting model for the chisel edge. Thrust and torque are obtained in terms of the geometric features of the drill, the cutting conditions and the properties of the machined material. (C) 1998 Published by Elsevier Science Ltd.
