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. Thereby, it is an economical method in manufacturing of SBGs. The results demonstrate that invented experimental cutting method of SBGs not only is less expensive than advanced CNC machining but also produces gears in a shorter time in comparison with the traditional cutting. This research consists of (a) geometric modeling of the spiral bevel gear, (b) simulating the traditional and our new nontraditional method using a CAD/CAE system, (c) process planning for CNC machining and PLC Programming, (d) experimental cuts with a three-axis CNC milling machine were made to discover the validity of the presented method.
In this paper, we attempt to manufacture the spiral bevel gear using a three-axis CNC milling machine interfaced with an additional PLC module based on traditional discontinuous multicutting method accomplished by using a universal milling machine interfaced with an indexing work head. In recent years, the development of CNC has made it possible to perform nonlinear correction motions for the cutting of spiral bevel gears. Combining numerical control with mechanic, electric, and data processing systems can lead to new methods of production. CNC machining nowadays makes more use of "Mechatronics" increasingly.
