On-Line Monitoring of Drill Wear in Machining of AISI 1040 Steel Using Virtual Instrumentation

Abstract:

In this research work, an attempt is made to develop the on-line wear state monitoring system during drilling process on Vertical Machining Centre (VMC). The main objectives of the present work is to predict the drill wear states of High Speed Steel (HSS) drill bit during the drilling of a AISI 1040 Steel work piece using standard data acquisition software Lab VIEW by the application of Virtual Instrumentation (VI). The drill bit wear states were analyzed using spindle motor cutting current signals. The effective drill wear model have been developed using spindle motor cutting current signals and the various cutting parameters through Lab VIEW, to predict wear states of the drill-bit. The developed on-line drill wear process monitoring system has been used for the continuous monitoring of the drill-bit status, and to exhibit the drill wear states. It was found that the developed model show a good agreement with the experimental data where the deviation in drill-bit wear is less than 7% for varying cutting conditions.
