Method & Evidence

AimTo investigate the impact of different cooling conditions (dry, wet, cryogenic) on tool wear, specific cutting energy, and surface roughness when machining Ti-6Al-4V, considering other machining parameters.

MethodExperimental Design (Taguchi Method) and Analysis of Variance (ANOVA)

ProcedureExperiments were conducted using a Taguchi design to systematically vary machining parameters (feed rate, cutting speed, depth of cut) and cooling conditions (dry, wet, cryogenic). The resulting tool wear, specific cutting energy, and surface roughness were measured and analyzed using ANOVA to determine the contribution of each factor.
