Abstract

An optimized design of the various machining parameters for the CNC oxy-fuel gas cutting process on SAE/AISI–4140 steel has been carried out by using DEA-based Taguchi methodology. SAE/AISI–4140 steel or Chromoly steel has high fatigue strength, impact resistance, durability, and noble ductile properties. The main output responses are bevel angle, dross breadth, and dross height, and the input parameters are nozzle speed, oxy-fuel speed, and torch height. Nine experiments were piloted based on a L9 orthogonal array of Taguchi design. The relative efficiency was determined from data envelopment analysis (DEA) method with Lingo version 14 software package. These scores were significantly affected by the machining parameters of oxy-fuel gas cutting process directly.
