Abstract :

Always in the production of turbine blades tried use less of secondary operations. Such as for increasing the quality of surface finishing that reduces the level of geometric accuracy. Accordingly in this paper, improvement of roughness and surface texture turbine blade directly with the optimization of machining parameters is been studied. Variable parameters of this research include tool diameter, depth of cut and feed rate. Experimental work by using a four-axis CNC milling machine was done on turbine blade aluminum. Experimental work by using four-axis CNC milling machine and the turbine blade was aluminum. Design of experimental was full factorial and All permutations of variable parameters been implemented. The surface roughness of machined areas by using surface roughness tester and the texture was examined using a stereo microscope. By using roughness tester, surface roughness of machined areas was measured. Form of surface texture was examined by a stereo microscope. Finally, by comparing data the best mode was introduced.
