Abstract
Burr is an undesirable jutting out formed as a result of plastic deformation of a metal during cutting and shearing operations. Burr needs to be minimized by an effective deburring process to improve the efficiency of machining and the quality of product. There is also a growing need for a measurement method or suitable measurement device to inspect burrs, favorably at drilled holes, sizes ranging from micro to macro. In fact, without an appropriate measurement method, it has become more difficult to examine and measure burrs formed on a free surface. In this work, a burr measurement system is developed using a conoscopic holography sensor, which offers certain advantages over interferometry, triangulation, and dynamic focusing, for point-by-point distance mapping. The measurement system is further improved to measure burrs on curved and inclined exit surfaces, whose range exceeds the measurement range of sensors, by using a Z axis adaptation method.
