Effect of grain wear on material removal behaviour during grinding of Ti-6Al-4V titanium alloy with single aggregated cBN grain
Source abstract
Abstract
Abstract This study aims to explore the grinding ability of as-sintered aggregated cubic boron nitride (AcBN) grains. Single-grain grinding tests of Ti-6Al-4V titanium alloy are conducted, and the wear characteristics of AcBN grains and their corresponding effects on material removal behaviour are investigated. Characterisation of the morphologies and micro-structure of AcBN grains and scratch morphologies is also performed. The grinding force ratio, material removal efficiency and grain wear characteristics of AcBN abrasives are discussed. Results show that the developed AcBN grains have multiple cutting edges and better self-sharpening ability than conventional monocrystalline cBN grains. In addition, AcBN grains feature a more stable grinding force ratio, larger material removal volume, higher material removal efficiency and longer steady-wear regions.
