4th Axis Machining
This video from Boxford demonstrates 4th axis machining to create an ornamental artefact. The full designing and making process is shown from a CAD design through to a finished product. Firstly the product is designed in a 3D modelling CAD package such as Pro/Desktop. It is then exported in STL format. Next the file is processed and the routing process is simulated using software. Next the 4th axis rotary indexing fixture is shown and raster machining takes place. The shape for the artefact is cut by the CNC machine to a high quality finish. Curriculum links include the use of CAD/CAM in the designing, simulating and making of a product and the use of 4th axis machining.
