  Product quality and sustainability in large dimension additive manufacturing
(LDAM) highly rely on the kinematic and energy performance of LDAM systems.
However, the mechanical vibration occurring in the fabrication process hinders
the further development of AM technology in industrial manufacturing. To this
end, a kinematic and energy performance optimization method for LDAM via
vibration-suppressed toolpath generation (VTG) is put forward. Kinematic
modeling of LDAM system and related energy consumption modeling are first
constructed to reveal that the toolpath of servo system assumes the main
responsibility for kinematic and energy performance in LDAM. The
vibration-suppressed toolpath generation (VTG) method is thus proposed to
customize servo trajectory for kinematic and energy performance optimization in
LDAM. Extensive numerical and physical experiments are conducted on the W16
cylinder, including the measurement and analysis of the mechanical vibration
amplitude, and assessment of the surface roughness before and after using the
proposed VGT. These experimental results demonstrate that our VGT is able to
simultaneously achieve kinematic and energy performance optimization in LDAM,
even though the fabricated part owns aberrant and complex morphology.
