Abstract

The practice of replacing cutting tools at the end of predetermined machining periods—based on past tool life data—could result in loss of production, quality and time. Real-time tool condition monitoring systems aid in continuous monitoring of tool health enabling timely decisions for tool replacement, thereby reducing cycle time and cost. This paper describes the development of a microcomputer-based system for measuring acoustic emission (AE) in metal cutting. The development includes the design, assembly and testing of a pulse counter. The methodology involved in establishing the relation between cumulative AE count and the cutting variables is presented. The developed system is compared with other similar AE systems to highlight its relative merits of simplicity, reliability and low cost.
