Grinding Force in Creep Feed Grinding of Titanium Alloy with Monolayer Brazed CBN Wheels

摘要

In this paper, grinding forces of titanium alloy Ti-6Al-4V are measured during creep feed grinding with brazed cubic boron nitride (CBN) wheels. The effects of process parameters on grinding force, force ratio and specific grinding energy are investigated in detail. The grinding force is low and force ratio is about 1.5, and the specific grinding energy of titanium alloys Ti-6Al-4V is about 65J/mm~3. Also, CBN wheels brazed with composite filler of Ag-Cu-Ti and 0.5wt.% lanthanum show better grinding performance than the counterpart brazed with Ag-Cu-Ti filler in this investigation.
