TOOL WEAR ON-LINE MONITORING IN END MILLING

Reliable tool condition monitoring is one of the important aspects in manufacturing automation in terms of achieving higher productivity and product quality. Appropriate and in time decision for tool change is significantly required in the machining systems. The objective of the research presented in this paper is to observe the application possibilities of the presented methodology for tool wear monitoring in end milling process. This methodology is based on the corelation between flank wear and cutting force components using statistical analysis. Force signal generated during machining process was used as input value of the statistical analysis. This signal was measured as a tool of sensing element to study flank wear on the cutting edge. The flank wear progression was monitored by means of the value of the I-kaz coefficient. The value of the I-kaz coefficient increases when the tool wear increases.
