CAD

Overview


Goal: Address challenges in the use of CAD modelling in the product realization process.

Uniqueness & Innovation: We focus on the use of application program interfaces (APIs) and other methods to extract data, create customizations, and automate functionality in CAD systems.  We also research methods and architectures to integrate CAD systems with other engineering and simulation tools for collaboration and dissemination.

Featured Projects


Embedding VR-Based Mechanical Tools into CAD Applications

This project presents an open/extensible architecture for embedding virtual reality-based mechanical tools within CAD systems to assist in assembly and disassembly analyses. This work is significant because it allows the user to perform immersive assembly/disassembly evaluations entirely  within the CAD system. 


Visualizing Large CATIA Models Interactively Over the Internet

This project investigates concepts for interactive 3D visualization of large CAD models and simulations over the internet. This will ensure better collaboration among engineers around the world without the need of specialized expensive CAD software that typically has high-end computer system requirements.


Reorganizing CAD Assembly Models (As-Designed vs. As-Built)

A CAD assembly model is a collection of components, comprised recursively of various levels of individual parts and sub-assembly models. Although the overall geometry is accurate, this hierarchy is often incorrect  from a manufacturing planning and simulation point of view. This work presents methods to create a reorganized CAD model assembly quickly and easily to ensure relevance for simulation and assembly planning tools that derive the manufacturing sequence directly from the CAD system.


DDEX - Dynamics Data EXtraction from CAD Geometric Models

This project created a module, coined DDEX, for rigid body Dynamics Data EXtraction from Computer Aided Design geometric models. It was developed to be used as part of the design analysis cycle (DAC) of the International Space Station (ISS) and the Synergistic Engineering Environment (SEE) at NASA.


 

Integration of Burr Information in CAD Models

Burr removal is a very costly process during manufacturing and can somtimes account for as much as one-third of the total cost of producing a part. This project focuses on a method to obtain burr location and severity information for a physical part and represent that information in the CAD model of the part.



Manufacturing-Oriented CAD design for Engineers

This project presents a design process which helps fill in the gap between Engineering Design and Manufacture by factoring in manufacturability and manufacturing process directly into CAD design. The result is a new and improved CAD model that conforms to Design for Manufacture (DFM) guidelines and easy to modify by design engineers.
