A Flezible Synchronous Powder Feeder for Electromagnetism Compress Digital Manufacturing of FGM Metal Component
Archiving functionally gradient materials (FGM) fabrication via digital manufac-turing methods has attracted considerable attention in recent years. In this paper, a new FGM powder feeder and its flexible numerical motors control solution used in electromagnetism compressed plasma deposition manufacturing process was developed. The motors control hardware circuit and its Superior computer control program was introduced and analyzed. The powder feeder unit was based on the timing belt driving and Pneumatic conveying principle. The Superior computer control program was based on lab windows/CVI program developing environment with good man-machine conversation interface. Tests were made with Ni-based alloy powders, Fe-based alloy powders and ceramic powders in the particle average diameter of 15-350 Microns. Results showed that powders mixtures obtained from the device are continuous and stable. The precision of delivering powders mixture can be within 2％ error scope comparing to the desired mixture quality and the flexible proportion of mixture can be easy changed in the computer control program by synchronously controlling the powder feeder rotation speed.
