Ceramics can highly withstand the environments of high temperature and serious erosion, it completely substitutes for alloys which reach their specific limitations. Turbine rotor operates in the compressed stage with temperature over thousand Celsius degrees; it must rely on excellent properties of ceramics to elevate the durability and lifetime. To manufacture complex ceramic component before, industry usually uses near net shaping or rapid prototyping (RP) processes.
A manufacturing process based on machining green ceramic turbine component is presented here. Initially, formulating a series of machining experiments for green ceramics to verify the idea of thesis, and analyzing the probability of Al2O3 ceramic as a turbine material. Firstly, it needs to check the machinability of green ceramic by face milling. Secondly, point milling the normal plate of green compact and the plate with analogical blade geometry to find a set of usable machining parameters (such as
revolution speed, feed rate, step over and cutting depth); meanwhile, addressing machining amendment by observing the final conditions of specific geometric characteristics on workpiece. Finally, try to machining green ceramic turbine successfully applying the above parameters.
