Titel
Simulation of friction between diamond and polycrystalline cubic boron nitride
Abstract
Grinding is a key technology in the manufacturing chain of polycrystalline cubic boron nitride (PCBN) cutting tools. However, high wear and low material removal rates during grinding lead to high manufacturing costs of PCBN cutting tools. Since friction is a major driver of grinding wheel wear, the friction related temperature between diamond as abrasive grain and PCBN as cutting tool material was investigated using the finite element method. Maximum temperatures of up to 720 °C and average temperatures of up to 165 °C were found on the PCBN surface depending on the PCBN specification, the friction coefficient, and the relative velocity.
