An empirical study on the generation of an edge radius in abrasive jet external deburring (AJED)

One attractive feature of external deburring with an abrasive jet is the ability to generate an edge radius at the deburred edges. The effects of various input parameters, viz. abrasive grit size, mixing ratio, nozzle diameter, stand-off-distance and the thickness of the specimen, on the response parameters were investigated on plaster-of-paris specimens by full factorial design. In addition to the extent of the edge radius generated, the variation in the diameters at the entry and exit side of the specimen were also investigated. The extent of the edge radius generated was affected significantly by the parameter stand-off-distance and the variations in the diameters were affected by the nozzle diameter. The results of the edge radius generation were applied to AISI 304 stainless steel burr specimens and verified. The details of the investigations carried out are presented in this paper.
