공구마멸에 따른 절삭력의 RMS 특성

The RMS Characteristics of Cutting Force Depending on the Tool Wear

With the use of the NC machine tool, the unmanned production system bas been growing recently in the manufacturing field. Thus there are problems with monitoring adequate tool fracture during the cutting process efficiently. This study was planned and carried out to discover a way of monitoring tool condition in ON-LINE systems during the cutting process. The acquisition of data in cutting force and tool wear has been made in the section examined, to extract the RMS value of the cutting force as specific factors in the cutting process. The fluctuation of the cutting force in accordance with tool wear has been analysed by using experimental data as the RMS characteristics. From the results, it has been shown that the fluctuation of the RMS values for the cutting force has a close relation to flank wear.
