- Description
- This research project aimed to develop a combined additive and subtractive manufacturing platform capable of rapidly producing large-scale prototypes for minimising material wastage. A design conceptualisation process led to the design and development of a system to deposit the additive material. The developed system was mounted to a large-scale CNC milling machine. This combination of additive and subtractive manufacturing into a single system integrated the separate benefits of the two independent technologies. Mastercam was selected as the preferred CAD/CAM software package to generate toolpaths for the additive and subtractive processes. The Beckhoff HMI provided a user-friendly interface to interpret the generated G-code files, set the Work Coordinate System, and control user-defined parameters such as the feed rate. An in-depth statistical analysis of the developed platform's dimensional accuracy, repeatability, stability, and material wastage was performed. In addition, the effects of the independent adjustment of the subtractive manufacturing process parameters such as the spindle speed, feed rate, depth of cut and stepover distance were considered. Finally, a cycle time comparison was performed in producing a working prototype between the developed HM system and a commercially available 3D printer. This research provided a platform for further investigation into the ever-expanding applications and benefits of rapid prototyping.
