This project consists of the design and development of a quality control vision system. Round Ground Metals produces small diameter Swiss screw machine quality stainless steel bars that will acquire various defects on them during production. The project consists of replicating the factory process of the steel bars rotating/moving along the factory line and implementing a system consisting of a Cognex In-Sight 7000 series industrial grade camera working with the In-Sight Explorer 4.9.1 software to detect any defect along the steel bars. Along with the detection, this project will have the ability to mark the defect on the bar and display all of the data gathered from the Cognex into a visual display screen that lets the user know the distance from the end of the bar that the defect is at, the size of the defect, and whether or not the diameter of the steel bar falls into the provided thresholds. After design is completed and prototype testing has been sufficiently done in the lab, the final design will then be transferred to Round Ground Metals for them to fabricate and eventually implement into their factory line.
