Hybrid LMD Additive and Subtractive Manufacturing
Update date:2018-10-24  author:NIIAM  Browsing volume:532


With the advent of industrial technology, the requirements of structure optimization and precision parameters for parts in aviation and aerospace are getting higher and tougher.  The manufacturing demand of high precision parts with complex geometry such as inner cavity and inner port, is increasing. While as with machining accuracy and surface quality guaranteed, the cutting tools of traditional machining method restricts the efficiency and precision consistency. Additive manufacturing is most ideal solution for complex parts forming, but still it is hard to meet the requirements of high precision and high surface quality.

This project aims for manufacturing of small and medium-sized complex precision structural parts to develop additive-subtractive integrated manufacturing technology. The team currently chose manufacturing and repairing of aerospace engine structure, molds with inner manifold etc. complex components as application targets, focusing on the researching of five-axial LMD additive and subtractive manufacturing technology of metal materials such as stainless steel, high temperature alloy, titanium alloy.
