Frictional Coefficient in Hot Drilling

  • Published:
Russian Engineering Research Aims and scope

Abstract

A method is proposed for determining the frictional coefficient in hot drilling. Methods of determining the frictional coefficient in analogous conditions are reviewed. A mathematical model of the frictional coefficient is derived for hot drilling, and the sequence of operations for determining the frictional coefficient is outlined.
