Lab Description

Our research involves the design and implementation of flexible machines, mechanical hardware, electronics, control and software. The goal is customizing, which is now in great demand. The new machine tool industry will allow corporations to respond to the ever changing patterns of world trade. The new manufacturing systems can analyze new products and automatically will produce near optimal plans for production. Adaptability is the key.

The research comprises a series of projects implementing an Intelligent Bending Workstation:

• Bend Sequence Planner
• BendCad Modeler
• Fine Motion Planner
• Grasping Planner
• Motion Planner
• Stacking Planner

Current Projects [Past Projects]

Bend Sequence Planner - Finds the best sequence of bending operations and repositionings of the part in the robot gripper to make a bent sheet metal part.	BendCad Modeler - Sheet metal design system for the Intelligent Bending Workstation
Fine Motion Planner - The fine-motion planner computes a sequence of robot moves to safely unload the workpiece from the bending machine.	Grasping Planner - Sheet metal grasp planning for the Intelligent Bending Workstation.
Motion Planner	Product Decomposition - a method of decomposing sheet-metal products into a few, easily manufactured parts
Stacking Planner - Generates plans for polyhedral sheet metal parts.	Tooling Planner - Supports various decision making steps related to bending tools and press-brake setups.
