Measurement of end-milling burr using image processing techniques:

This paper presents a method that has been developed to measure the height of end-milling burr on the edges of a work-piece using techniques of image processing. This simple and economical system consists of a microscope with a digital camera mounted on the viewing lens and a personal computer for image processing. An image is captured and then processed whereby the whole burr profile is analysed and compared to traditional methods, where normally a few readings are taken at random locations. An added feature of this system is that disorientation of the reference horizontal axis, along which burr height measurements are taken, on the work-piece during image capture is catered for with relevant image processing functions. In addition, the system determines and plots the height of the burr against its location, together with the average burr height, which can be used later for deburring or further analysis.
