Description

technical field [0001] The invention belongs to the field of machine tool design, and relates to a compound manufacturing machine tool of adding and subtracting materials. Background technique [0002] With the increasing demand for precision and complex parts in the aerospace, nuclear energy, and ocean engineering manufacturing industries, traditional subtractive manufacturing, such as turning, milling, planing, drilling and grinding, has been unable to achieve complex parts. Manufacturing requirements for components. The currently emerging additive manufacturing technology has been used in the manufacture of complex parts due to its flexibility, high efficiency, and energy saving. However, the precision of complex parts formed by additive manufacturing equipment is far lower than the actual requirements. The secondary processing on the subtractive machine tool leads to low processing efficiency and changes in the positioning reference, which prolongs the production cycle ...
