Surface topography in ball end milling process: Description of a 3D surface roughness parameter

In the field of free-form machining, CAM software offers various modes of tool-path generation, depending on the geometry of the surface to be machined. Manufactured surface quality results from the choice of machining strategy and machining parameters. The objective of this paper is to provide a 3D surface roughness parameter that formalizes the relative influence of both machining parameters ...

Modeling of Turn-milling Process

This paper presents an analytical approach for modeling of turn-milling which is a promising cutting process combining two conventional machining operations; turning and milling. This relatively new technology could be an alternative to turning for improved productivity in many applications but especially in cases involving hard-to-machine material or large work diameter. Intermittent nature of...

Characterization of 3D surface topography in 5-axis milling

Within the context of 5-axis free-form machining, CAM software offers various ways of toolpath generation, depending on the geometry of the surface to be machined. Therefore, as the manufactured surface quality results from the choice of the machining strategy and machining parameters, the prediction of surface roughness in function of the machining conditions is an important issue in 5-axis ma...

MODELING SURFACE TENSION AND WALL ADHESION IN MOLD FILLING PROCESS

Abstract: In this study an algorithm for mold-filling simulation with consideration of surface tension has been developed based on a SOLA VOF scheme. As the governing equations, the Navier-Stokes equations for incompressible and laminar flows were used. We proposed a way of considering surface tension in mold-filling simulation. The proposed scheme for surface tension was based on the conti...
