A NEW APPROACH TO SIMULATION AND ANALYSIS OF HOT DIE FORMING PROCESS FOR MANUFACTURING CUTICLE NIPPER BASED ON CAD/CAE SYSTEM

Abstract

This paper presents simulation and analysis of hot die forming process for manufacturing cuticle nipper, which is a very useful tool with high demand in the body-care product maket. Based on the application of the CAD/CAE system with finite element method (FEM) including the softwares DEFORM-3D, KOMPAS 3D, Geomagic Design X and ANSYS, the authors developed a closed-loop process “design-simulation-analysis”, which helps properly to forecast forming process, determine the force with influence factors, residual stresses, heat analysis and processing, ect. Sixty numerical experiments with different input data including shape of workpieces, temperature and velocity of forging machine were carried out. The obtained simulation results allowed for indicating product defects, reducing design error, selecting hot metal preparation, machines and forging procedure suitably. Therefore, the outcome of this study has a high practical significance in the area of metal forming and related industries in Vietnam.
