The advantages of a vision system on a CNC machine would allow higher precision parts, and less mistakes in machining operations. As shown by this work the tool runout from the axis of rotation of the spindle can be measured. Averaging duplicate frames and spline fitting helped to remove random noise and increased the accuracy of the runout measurements. However, more work on the edge detection is necessary to improve the accuracy and precision of the runout measurements. It was also shown that the edge is a gradient of pixels. Improving the detection of the actual edge for the object in the image will require better algorithms.
