A control chart for drilling burr formation for stainless steel was developed. The chart, based on experimental data, is a tool for prediction and control of drilling burrs. As an introductory study, one workpiece material, stainless steel AISI 304L, and one drill geometry, split point twist drill, were used. Burr classification was carried out based on the geometric characteristics and the size of the burrs. New parameters consisting of cutting condition variables and drill diameter were developed, and used to show a unique distribution of the burr types. Burr types and the resultant burr size showed great dependence on the new parameters regardless of the drill diameter. Through the chart, burr type can be predicted with given cutting conditions. Also cutting conditions that are believed to create preferred burr types can be selected.
