Abstract

Burr is an unintentional residue caused by plastic deformation of the workpiece during machining such as drilling and milling. Burrs generated in the intersecting holes deep inside the work piece are difficult to access and remove. In this work, the effects of various AFM process parameters are investigated for holes intersecting at right angle with offset. Burr edge is formed in the wall of the primary hole by the secondary hole. Experiments were carried out for AL6061 specimens with flow distance, abrasive particle size, abrasive particle concentration, abrasive fluid viscosity and flow speed allocated in L8(25) orthogonal array. The mean value analysis indicates that deburring is strongly dependent on the flow distance while the effect of flow speed is minimal.
