| Abstract | The Turgo turbine model is developed based on the parametric dimensions from the onedimensional calculation using Solidworks. It is then imported into MasterCam to generate tool path conducting ruled surface milling. After that, it is post-processed in Mathamatica based on Inverse Kinematic. Using the NC file with G-code, the verification is implemented in Vericut. When tool path is optimized, the prototype is produced with Haas 5-Axis machine with flank milling. The e-Design concept is applied during the optimization process. The integrated e-design phase and manufacturing phase is working in parallel. The designed model is revised several time according to the optimization of tool path generation based on the verified results using the virtual 5-Axis machine in Vericut with good surface finish, less manufacturing time, the avoidance of tool break, tool wear, and less scallop. The optimized machining sequence includes roughing of the extra materials first, then finishing the 20 blades using flank milling 10 mm bull-end tool. The total manufacturing time for implementing the optimized too path is 4 hours and 45 minutes. With this tool path, the surface finish, the manufacturing time and the collision avoidance with less tool travel are optimized. Still, there is one scallop in the bottom as the big tool effect. However it is not the critical since it has no affect the flow mechanism and can be developed later. |
