Integrated solid modeller based solutions for machining

Most existing machining simulation software is geometric in nature, and ign ores the physical aspects of the process. This paper reports research progr ess towards developing a comprehensive physical machining process simulatio n program based on a solid modelling kernel. Both flat and ball end tools a re modelled, and multi-axis motion is supported. A Finite Element Analysis model is used to predict both tool and part deflection. A special sweep rep resentation is used for Boolean part model updating. The system can be used for prediction as well as for intelligent factory floor control. Several e xamples of completed work are included to illustrate developed techniques. A discussion section presents computation time data, and outlines how paral lel processing could be utilised.
