1.0 Overview: Optimized drilling parameter
1.1 Background: Cost minimization in drilling operation
The formation of burrs is a significantly undesirable by product of drilling operations in manufacturing plants. A burr, which is the rough edge that remains on a work piece after drilling, is formed whenever a drill bit approaches the exit surface of a work piece, appearing as a short mound of material (see Fig. 1) [1]. Because of their uneven shape, burrs cause a multitude of problems in manufacturing. For example, burrs not only cause jamming and misalignment during assembly by interfering…
