SUMMARY:VASCO: Volume and Surface Co-Decomposition for Hybrid Manufacturin
 g
DESCRIPTION:Technical Papers\n\nFanchao Zhong, Haisen Zhao, Haochen Li, Xi
 n Yan, and Jikai Liu (Shandong University); Baoquan Chen (Peking Universit
 y); and Lin Lu (Shandong University)\n\nAdditive and subtractive hybrid ma
 nufacturing (ASHM) involves the alternating use of additive and subtractiv
 e manufacturing techniques, which provides unique advantages for fabricati
 ng complex geometries with otherwise inaccessible surfaces. However, a sig
 nificant challenge lies in ensuring tool accessibility during both fabrica
 tion procedures, as the object shape may change dramatically, and differen
 t parts of the shape are interdependent. In this study, we propose a compu
 tational framework to optimize the planning of additive and subtractive se
 quences while ensuring tool accessibility. Our goal is to minimize the swi
 tching between additive and subtractive processes to achieve efficient fab
 rication while maintaining product quality. We approach the problem by for
 mulating it as a Volume-And-Surface-CO-Decomposition (VASCO) problem. Firs
 t, we slice volumes into slabs and build a dynamic-directed graph to encod
 e manufacturing constraints, with each node representing a slab and direct
 ion reflecting operation order. We introduce a novel geometry property cal
 led hybrid-fabricability for a pair of additive and subtractive procedures
 . Then, we propose a beam-guided top-down block decomposition algorithm to
  solve the VASCO problem. We apply our solution to a 5-axis hybrid manufac
 turing platform and evaluate various 3D shapes. Finally, we assess the per
 formance of our approach through both physical and simulated manufacturing
  evaluations.\n\nRegistration Category: Full Access\n\nSession Chair: J. A
