Title: 3303 Monitoring of Burr and Prefailure Phase in Microdrilling Operations using Thrust Force Signals
Abstract: The purpose of this study is to investigate effectiveness of thrust force for estimation of burr occurred at outlet of drilled hole and the prefailure phase of micro drills in drilling holes through thin stainless steel plate (JIS SUS304). Micro drilling tests, in which feed rate, step feed length, and diameter of micro drill are adopted as experimental parameters, were carried out to measure thrust force during drilling operations. On the other hand, tool wear of cutting edge and burr occurred at outlet of drilled hole were measured at intervals of constant number of drilled holes to consider their relationship to thrust force. As a result of some considerations, thrust force during micro drilling can be related with height of burr occurred at outlet of drilled hole and prefailur phase of micro dills.
