Hybrid additive–subtractive manufacturing (HASM) is a revolutionary technique that
fabricates complex-shaped parts in high precision. One setup to finish complicated …

Metal additive manufacturing (AM) processes often fabricate a near-net shape that includes
the as-designed part as well as the sacrificial support structures that need to be machined …

Hybrid additive–subtractive manufacturing (HASM) is a revolutionary technique that, the
interplay between additive and subtractive processes within an integrated machine tool …

Part orientation and support structures are crucial to the quality of metal parts by laser
powder bed fusion. Computer-aided solutions for part orientation can be used to support …

Abstract Design requirements for moving parts in mechanical assemblies are typically
specified in terms of interactions with other parts. Some are purely kinematic (eg, pairwise …

One of the main concerns in design and process planning for multi-axis additive and
subtractive manufacturing is collision avoidance between moving objects (eg, tool …

This paper proposes a novel density-based method for structural design considering
restrictions of multi-axis machining processes. A new mathematical formulation based on …

Bridging in additive manufacturing (AM) parts occur between two points without any support
from below. If the material extruded between these points is dangled (ie, not horizontal), this …

Mechanical assemblies can exhibit complex relative motions, during which collisions
between moving parts and their surroundings must be avoided. To define feasible design …

Ensuring the removability of support structure and improving the surface quality of assembly
interface are two key requirements to guarantee a model a valid fabrication and promote its …
