Abstract

Micro-milling experiments of HPb63-3 lead brass were conducted on micro-machine by using TiAlN coated tungsten carbide micro-diameter cutter. Wear and breakage morphologies of micro-tool were analyzed. Wear and breakage of micro-diameter cutter mainly occurred in tool nose and the wear and breakage morphologies shown distinct size effect. The main failure modes of micro-tool were coating peeling and tool nose breakage. Adhesive and abrasive wear were typical damage mechanisms of micro-tool. Diffusing effect occurred between tool and workpiece, which did not contribute to the tool wear obviously.
