CONGRESO Study of Combined Machining Parameters on 3D Roughness Behaviour in Moulds and Dies


In order to process materials with special characteristics (e.g. brittleness, hardness and stiffness), high-speed machining (HSM) has gradually become one of the most popular metal cutting and machining methods. In the die-mould manufacturing industry, HSM is mainly used for workpiece machining. By applying HSM technology, it is possible not only to obtain specific surface roughness parameters, but also to improve surface quality generally. This is because the technological parameters of the machining have an impact not only on surface quality parameters such as surface texture and roughness, but also on surface micro-hardness. This paper contains detailed results on how high-speed milling impacts on 3D surface texture and roughness parameters. The ISO25178 standard of geometric product specification was used to characterize surface roughness. This paper also offers a comprehensive review of how HSM impacts on industry and the surface micro-hardness with regard to particular materials. Carefully designed experiments were conducted, varying technological parameters, which were recorded along with the relevant 3D roughness parameter measurements. Significant conclusions are based on the compilation of statistical models, to find differences between groups of means. Analysis of variance was applied in this research, using R-commander software for ANOVA analysis. This paper also proposes initial recommendations for mould and die manufacturers to deploy HSM to improve the machining process and surface quality.
