This is a clear indication that different CAM systems (that is, Art-based, Mechanical-based and others) will yield different machining results even when similar machining strategies are employed. There was a significant difference in the resulting surface texture and cycle times between Mastercam® XIV and ArtCAM® 2013 machined free-form surfaces. The generated NC-files were fed into a 3-axis CNC Vertical Machining Center (VMC) for SSM. In this study, CAD/CAM designed free-form products were used to assess cycle times and surface quality of machined sculptured surfaces with NC-files generated by Mastercam® XIV and ArtCAM® 2013, respectively. Therefore, instead of developing complex algorithms to improve the quality of machining, cycle times and surface texture, can be used to assess the quality of machining attainable in commercially available CAD/CAM systems if the performance on these parameters is acceptable. The upgrading of CAD/CAM systems implies improvements in machining strategies and the attendant sculptured surface machining (SSM) efficiency. The capabilities of commercially available CAD/CAM systems in relation to SSM will among other factors, be influenced by the computation times, cycle times as well as the resulting surface texture. The selection of machining parameters in commercially available CAD/CAM packages will in most cases depend on the choices provided in the software for the various machining strategies. The efficiency with which sculptured surfaces are machined is dependent on the machining strategies used.
