An Evaluation of Some Specifications of Turbine Blades Made by 3D Printing and Machining on CNC Milling Machines

Authors: ,

Abstract: This paper presents the research results on manufacturing turbine blades in turbocharger machined on Haas VF2 module TRT 160 5-axis CNC milling machine and by 3D printing method on Metal 3D printer HBD-280 series with the same material AlSi10Mg. The research sample is the compressed turbine blades in the HX40W turbocharger mechanism. CAD data files for machining programming and 3D printing of turbine blades are scanned from an ATOS Core 80 scanner with GOM and Geomagic Design X softwares. Some specifications of the two manufacturing methods are also presented. Research results show that the error of average diameter and surface roughness of 3D printing method is larger than that of machining on a CNC milling machine.
