Model for surface-roughness parameters determination in a virtual machine shop environment.

Bilalis, N.; Petousis, M.; Antoniadis, A.

A virtual reality machine shop environment was developed and integrated with a graphical model for the calculation of quantitative data affecting the roughness of a machined surface. During the machining process simulation in the virtual environment, material removal and milling machine axes kinematics are visualized in real time and qualitative parameters related to the process feasibility are evaluated. The model determines the machined surface topomorphy as a cloud of points retrieved from the visualization system Z buffer and surface roughness is calculated. The current study is focused on the methodology for the verification of the quantitative data acquired by the system. Results were verified with data determined in cutting experiments and by another numerical model that was integrated into the system. The results were found to be in agreement with both the numerical model and the experiments.
