Burr Measurement System for Drilled Hole at Inclined Exit Surface

摘要

Burr is an undesirable projection as a result of plastic deformation in metal cutting and blanking operation. Burr minimization and effective deburring process are required strongly to improve the efficiency of machining and the quality of product. The necessity of a suitable measurement device for inspecting drilled hole from micro to macro burrs is required. The burr measurement system uses conoscopic holography sensor which offers certain advantages over interferometry, triangulation and dynamic focusing, for point-by-point distance mapping. In terms of this work, the improvement of burr measurement system which has ability to measure burr on curved and inclined exit surfaces which causes the out of range signals will be introduced and discussed in this paper.
