Abstract

In order to provide a framework for the evaluation of, and need for, sensor information appropriate to real time manufacturing control, a workcell based on a 5-axis machining center was developed. This workcell defines a problem space within which automated inspection is to be applied. Primarily, we are interested in evaluating the use of machine vision and Coordinate Measuring Machines (CMM's) as means to provide information to an automated workcell controller. This controller will use these sensing technologies in a hierarchical fashion exploiting the speed vs. accuracy tradeoff's characteristic of tactile and non-tactile coordinate acquisition. We have implemented an Octree solid modeling system which has the capabilities of model generation from the information provided by the vision system. In addition, the Octree method lends itself to simulating the actual manufacturing process. Our system reads the machine tool G-Codes generated by our CAD system and simulates the material removal operation by successively removing intersections between the tool and workpiece. This machined model is then used for automatic inspection sequence generation. This paper will describe the framework and architecture of our automated inspection system, as well as specifics relating to the Octree modeling system.
