| Broadly, the research activities in the laboratory
focus on spatial and physical modeling in support of industrial
automation -- so that physical artifacts can be represented,
analyzed, designed, and manufactured based on computer representations
and algorithms. Current and recent projects include:

Existing physical artifacts including sculpture, mechanical parts, and anatomical structures are commonly acquired by modern surface and volumetric scanning technologies for archival, visualization, and diagnostic purposes. While the native representations for such data are largely sufficient for visualization purposes, more advanced field simulation currently requires extensive manual conversions into simplified surface and volume meshes compatible with the traditional finite element analysis pipeline. |

Modern manufacturing enterprises achieve unprecedented levels of efficiency, flexibility, and productivity through optimization, reconfigurability, and reuse. This project aims to develop computational infrastructure to support such an enterprise via validation, planning, and synthesis of manufacturing process plans. Reconfigurable devices, such as robots, tools and fixtures, are required to respond efficiently to product/process changes, with minimal disruption to existing device setup and operation. Specific examples of manufacturing planning tasks inlcude
1. Can existing devices in a facility be re-used to accommodate a
specified change in product design and/or process plan?
2. If so, how should they be reconfigured?
3. If not, how can reconfigurable devices be selected and/or designed to perform desired function?
The key concept in reconfigurable manufacturing is that of a workspace: a set of configurations associated with a particular device, function, or process. In this project we define and construct workspaces for a number of common manufacturing devices, and show how workspaces can be used to support validation, planning, and synthesis tasks in reconfigurable manufacturing.

Geometric modeling of mechanical components and systems has become the key enabling technology for modern production across all disciplines, and can no longer be viewed as a mere supporting activity. Geometric models themselves must be manufactured: designed, analyzed, inspected, exchanged, assembled, and maintained - virtually, in software - throughout the entire product life cycle. |

The term "meshfree" indicates that modeling and/or analysis technique does not require that geometric model is represented by a conforming mesh of elements. A background mesh may or may not be used for computations, but the geometric representation neither depends on it nor conforms to it. |
