Conceptual design of casting patter

Abstract

The present trend of design for turbine blade is basically done by investment casting process, which incurs a lots of disadvantages like labour cost, Working skill, machining cost etc. Hence in order to overcome these problems our main objective is to cast the same blade with an conceptuallyalternative valid design. So this may reduce all the problem associated with the ongoing process. Moreover since now a days we people have a lots of advanced and modernized machine tools like CNC, DNC, Automated lathe etc which can take care for all the machining process after the job has been casted by say sand casting process and hence reduce surface roughness etc. So overall we can design a number of conceptually alternate ways for casting process of the turbine blade. But after having all those alternatives we need to select the best suitable alternative among them. Then we go for casting of the blade.
