This study combined finite element method (FEM) simulations and physical experiments to develop a novel cold bulging process, with the aim of studying mitigating quenching residual stresses in 2A14 tapered cylinder forgings. The samples underwent at different ratios (0–4.0%) evaluate stress reduction performance (via hole-drilling strain-gauge method) improvements their mechanical properties. F...

A systematic approach to nonconformity management and continuous improvements are the key elements of quality system. The objective this paper is present improvement for a manufacturing company producing forgings through combination several statistical methods control techniques. First, Pareto analysis was applied, followed by 8D (eight disciplines) methodology using structured eight-step probl...
