International Classification:

G06F 19/00
US Classification:

700187000, 700086000
Abstract:

A system, method, and computer program comprising loading a part definition; receiving a user selection of a local area of a part to be cut, the part corresponding to the part definition; creating a cut area max/min box according to the user selection; preparing a tracing according to the max/min box; identifying cut area containment shapes; setting trim shapes according to the cut area containment shape; creating cut-regions according to the trim, blank, part and check shapes; and creating a tool path program to cut the part, and appropriate means and computer-readable instructions.

Filed:

Sep 6, 2019
Appl. No.:

17/632953
Inventors:

- Plano TX, US
Timothy R. Fithian - Commerce Township MI, US
Jeffrey A. Jaje - Macomb Township MI, US
International Classification:

B22F 10/85
G05B 19/4099
B33Y 50/02
Abstract:

Methods for computer-aided design, engineering, visualization, or manufacturing (CAx) operations and corresponding systems and computer-readable mediums are disclosed herein. A method includes receiving, by a data processing system, a computer-aided design, engineering, visualization, or manufacturing model of a product to be manufactured. The CAx model comprises a bridge structure and at least two leg structures. The method includes slicing the CAx model into a plurality of layers, wherein each layer in each leg structure has a corresponding layer number in a sequence of layer numbers for that leg structure. The method includes maintaining an association between corresponding layer numbers of each of the leg structures. The method includes manufacturing the product according to the sequence of layer numbers and the associations, including manufacturing at least one layer of each leg structure in turn. Each leg structure completes manufacture at substantially the same time.

Filed:

Sep 5, 2018
Appl. No.:

16/476629
Inventors:

- Plano TX, US
Michael Taesch - Rochester Hills MI, US
Timothy R. Fithian - Commerce Township MI, US
William Vittitow - Garden Grove CA, US
Mai-Anh T Bui - Huntington Beach CA, US
Ashish Joshi - Cypress CA, US
International Classification:

G06F 17/50
B29C 64/393
Abstract:

Systems and methods for designing and manufacturing an additive manufacturing (AM) model. A method includes computing a wedge plane and initial toolpath for an AMmodel based on a breaking angle. The method includes trimming an excess toolpath of the AM model using a breaking plane. The method includes building the toolpath along the normal of a first layer and trimming based on a next layer. The method includes building a next wedge of the toolpath in the direction of a wedge plane used to trim a previous wedge The method includes storing the toolpath.

US Patent:

20160263832, Sep 15, 2016
Filed:

Mar 10, 2015
Appl. No.:

14/643320
Inventors:

- Plano TX, US
Timothy R. Fithian - Birmingham MI, US
David Madeley - Louth, GB
International Classification:

B29C 67/00
Abstract:

A component of a computer-aided manufacturing (CAM) system may be configured to cause a processor to generate instructions that specify how a 3D-printer additively builds an article on a build plate via depositing material from a deposition head. The generated instructions specify how a deposition head and/or a build plate of the 3D printer moves relative to each other to build an article on the build plate such that material outputted from the deposition head is deposited in successive layers in a build direction. The processor may receive a user selection of a spiral pattern selection. For at least portions of each layer of at least a portion of the article, the generated instructions specify that the deposition head continuously deposits material in a spiral pattern between radially outward and radially inward portions of the article.

Inventors:

- Plano TX, US
David Madeley - Louth, GB
Timothy R. Fithian - Birmingham MI, US
International Classification:

B29C 67/00
Abstract:

A component of a computer-aided manufacturing (CAM) system may be configured to cause a processor to generate instructions that specify how a 3D-printer additively builds an article on a build plate via depositing material from a deposition head. The 3D printer is configured to cause the deposition head to rotate in order to selectively change, an angle of a deposition axis at which the deposition head outputs material. The generated instructions specify how the deposition head is operated by the 3D printer to build the article on the build plate such that material deposited along a side wall surface of the article is provided by the deposition head having its deposition axis orientated at an angle determined based at least in part on an angular orientation of the side wall surface.
