Contact Interaction Simulation Tool Chip Based on Quantum Mechanical Calculation
Abstract
Objective: to study the reasons for the dependence of the friction when cutting and constancy of the specific friction force on the treatment conditions. Methods: electron microscopic study of structural transformations and quantum- mechanical calculations of the interatomic interaction material chips and particles of the tool material. Research results: was shown that the cause of the temperature dependence of the coefficient of friction when cutting is the structural transformations in the near-contact layers of chips, and the constancy of the specific friction force when cutting associated with achievement in local volumes in the near-contact layer of chip limiting density of dislocations and their amortization.
