Real-time tool wear monitoring based on feed motor current in chuck- center mounting condition
On-line tool wear condition monitoring is a significant area of research in automated machining process.This study concerns the development of an on-line tool wear condition monitoring system based on a fuzzy logic scheme.The feed motor current was measured and used as the input of a fuzzy process. Previously, most studies in this field have assumed the workpiece as rigid.However, in practice, cutting force causes the elastic deflection on workpiece and changes actual cutting depth.Therefore, due to coupling between actual depth of cut and feed motor current, the measured current values vary on cutting length according to workpiece elastic deflection pattern.This oscillation in current signal which is used as the input of monitoring system, can affect output results.Thus, in this study in order to achieve more accurate results, the workpiece clamping condition has been considered and through monitoring software a correction factor has been applied on outputs.Experimental results indicate that the proposed method can be reliable for practical applications of tool monitoring systems.
