A Novel Metamorphic Mechanism for Efficient Additive Manufacturing
Abstract
A novel metamorphic rolling mechanism (MRM) based on genetic evolution
synthesis that realized multiway, multiple-DOF and synchronous plastic forming in arc
based deposition processing of components with variable wall thickness is proposed
in this paper. Topology and mechanical structure of the metamorphic mechanism is
presented and D-H equation is derived. Experiments show that firstly efficient
manufacturing of components with variable wall thickness can be realized by
synchronous rolling in vertical direction. Secondly precision and surface
configurations of the components are improved compared with that of freeform
deposition manufacturing. The metamorphic mechanism provides possibilities of
efficient hybrid manufacturing of near net shape components with variable wall
thickness.
