Drilling Burr Control Chart -Adding a Material Property Axis


A 2-dimensional drilling burr control chart was developed by Jinsoo Kim (2000, 2001) which quantifies the effects of feed rate and speed on burr size; but, each chart is only useful for a specific type of material, and many materials have yet to be studied. What is needed is an understanding of how material properties and their dependence on temperature effect burr formation, to avoid the necessity of creating a burr control chart for every type of material. The goal is to use previous studies of material properties and burr formation to develop a third axis on the burr control chart. Ideally, one could create a dimensionless number that is a function of the material properties that most effect burr formation.
