SUMMARY:Waste-to-Value: Reutilized Material Maximization for Additive and 
 Subtractive Hybrid Remanufacturing
DESCRIPTION:Fanchao Zhong, Zhenmin Zhang, Liyuan Wang, Xin Yan, Jikai Liu,
  Lin Lu, and Haisen Zhao (Shandong University)\n\nRemanufacturing effectiv
 ely extends component lifespans by restoring used or end-of-life parts to 
 like-new or even superior conditions, with an emphasis on maximizing reuti
 lized material, especially for high-cost materials. Hybrid manufacturing t
 echnology combines the capabilities of additive and subtractive manufactur
 ing, with the ability to add and remove material, enabling it to remanufac
 ture complex shapes and is increasingly being applied in remanufacturing. 
 How to effectively plan the process of additive and subtractive hybrid rem
 anufacturing (ASHRM) to maximize material reutilization has become a key f
 ocus of attention. However, current ASHRM process planning methods lack st
 rict consideration of collision-free constraints, hindering practical appl
 ication. This paper introduces a computational framework to tackle ASHRM p
 rocess planning for general shapes with strictly considering these constra
 ints. We separate global and local collision-free constraints, employing c
 lipping planes and graph to tackle them respectively, ultimately maximizin
 g the reutilized volume while ensuring these constraints are satisfied. Ad
 ditionally, we also optimize the setup of the target model that is conduci
 ve to maximizing the reutilized volume. Extensive experiments and physical
  validations on a 5-axis hybrid manufacturing platform demonstrate the eff
 ectiveness of our method across various 3D shapes, achieving an average ma
 terial reutilization of 69% across 12 cases.\n\nRegistration Category: Ful
