Investigation of the Effect of Workpiece Resolution on Milling Simulation Accuracy in Production Module 3D CAE Software

Abstract

The aim of this work was to present the effect of workpiece resolution on simulation accuracy in Production Module 3D CAE software. The concept of resolution and working principle of CAD model conversion into proprietary *.TWSM format was explained. Next, the effects of model resolution on simulation results were presented, using an example of a face milling operation. Four different workpiece model resolutions were used, including the resolution value recommended by the software developer. Comparison of simulation results for different workpiece resolutions was conducted, obtained results were analysed, with particular focus on the effect of workpiece resolution on simulated cutting force values. The authors have found a substantial link between workpiece resolution, material removal rate and simulation accuracy.
