ResumoDeburring operations account for a considerable portion of the cost of machined components and there have been efforts to automate deburring for some time. This has been done with robots carrying deburring tools and sensor feedback for tracking the edge. The deburring and chamfering of precision components is complicated by the fact that the burr may be very small (0.040 mm or less) and conventional sensing techniques for burr following such as measurement of force on the deburring tool are unreliable due to low metal removal rates. Acoustic emission has been under development as a sensing technique for precision deburring feedback. This paper will establish the basis for use of acoustic emission in chamfering and deburring. The results of recent research to develop and evaluate a signal conditioning and control strategy for chamfering and deburring 6061-T6 aluminum will be presented.
