This paper presents research results on direct machining of Turbine blades in Turbocharger from point cloud data. In the study, the ATOS Core 80 scanner was used to create a point cloud file from the parts of the compression Turbine blades of the sample Turbocharger. From the point cloud data file, without any processing, the machining code is programmed using Inventor Professional software. The 5-axis HASS VF2 CNC milling machine is used to perform the machining steps. To evaluate the accuracy of machining parts compared with sample parts, the CMM coordinate measuring machine is used, and the original point cloud data file is compared with the detailed point cloud data file after pro... |
The turbine shaft is an important part of the turbocharger structure. This part requires quite high hardness, especially when operating it needs high strength to ensure the working conditions with very high speed, pressure and temperature. This paper presents the research results of the effects of temperature and heat retention time at high tempering on the hardness and tensile strength of the turbine shaft in the HX40W model turbocharger structure made of 42CrMo steel. |

Turbine blades have a very special structure. Previously, their manufacture was mainly done by casting in metal molds. This paper presents the results of research on the effects of technological parameters on the accuracy and surface roughness of turbine blades when machining on the 5-axis CNC milling machines. In the study, reverse engineering method was used to create the file designed according to the template, and the machining programming was done on Mastercam software, using the Postprocessor to output the machining code suitable for machining on the CNC milling machines. Taguchi method is applied in experiments, analyzing the influence of turbine blade machining technology para... |
