This research explores the experimental analysis of titanium alloy using an
innovative approach involving a 2–7% carbon nanotube (CNT)-infused cubic boron
nitride (CBN) grinding wheel. Employing a full-factorial design, the study
systematically investigates the interactions among varied wheel speed, workpiece
feed rate, and depth of cut, revealing compelling insights. The integration of
CNTs in the CBN grinding wheel enhances the machining performance of titanium
alloy, known for its high strength and challenging machinability. The experiment
varies CNT infusion levels to assess their impact on material removal rate (MRR)
and surface finish. Significantly, MRR is influenced by CNT content, with 5% and
above demonstrating optimal performance. The 7% CNT-CBN wheel exhibits a
remarkable 61% improvement in MRR over the conventional CBN wheel. Interaction
studies highlight the pivotal role of depth of cut, indicating that slower
speeds and feeds, combined with increased depth of cut, enhance abrasive grit
penetration and produce superior surface finishes. The damping coefficient,
reflective of wheel strength and longevity, follows the MRR trend, with the 7%
CNT-CBN wheel displaying the highest value. SEM and AFM images confirm improved
surface finishes and reduced grinding burns. This study presents a novel
strategy for studying the MRR and Ra while grinding titanium alloy with
CNT-infused grinding wheels, offering valuable insights for the field.
