US Patent:

20220373996, Nov 24, 2022

Filed:

Jul 27, 2022

Appl. No.:

17/875286

Inventors:

- San Francisco CA, US
Ravi Kumar Burla - Novi MI, US
Jesus Rodriguez - Farmington MI, US
Benjamin McKittrick Weiss - Tualatin OR, US
Nan Li - Mount Waverley, AU

International Classification:

G05B 19/414
G06F 30/20
G05B 19/418

Abstract:

Methods, systems, and apparatus, including medium-encoded computer program products, for computer aided design of physical structures using generative design processes, where the 3D models of the physical structures are produced so as to facilitate manufacturing of the physical structures using 2.5-axis subtractive manufacturing systems and techniques, include: obtaining a design space for an object to be manufactured, design criteria, and load case(s); iteratively modifying a generatively designed 3D shape of the modeled object, including generating 2D profile representations (corresponding to discrete layers) of an updated version of the 3D shape, extruding the 2D profile representations along the milling direction, and forming a next version of the 3D shape of the modeled object from a combination of the 3D representations produced by the extruding; and providing the generatively designed 3D shape of the modeled object for use in manufacturing the physical structure using a 2.5-axis subtractive manufacturing process.
