Method & Evidence

AimWhat is the optimal combination of Wire EDM parameters (current, pulse on time, pulse off time) to achieve the lowest surface roughness in the fabrication of AISI 4140 steel spur gears?

MethodExperimental Design (Taguchi Method)

ProcedureA series of controlled experiments were conducted using a CNC Wire EDM machine. The Taguchi L9 orthogonal array was employed to systematically vary three key parameters: current, pulse on time, and pulse off time. Surface roughness was measured for each experimental run, and the Taguchi method was applied using Minitab software to analyze the results and determine the optimal parameter settings.
