- G131012 Cutting of Cemented Carbide Using Five Axis Machine Tools : Direct Carving After Electric Discharge Method
抄録
The cemented carbide is attracting attention as a die material.However,cemented carbide is a difficult-to-cut materials and the tool wear becomes hard in the machining.Electric discharge machining is used for the die machining with complex curved surfaces.Electric discharge machining layer is required polishing.Cleanup operation of electrical discharge machining layer is manual labor,there is a problem such as an increase in manufacturing cost,and work efficiency decline.Therefore,it is possible to improve the efficiency of the die manufacture by total automation and polishing of complex surfaces by using the five axis machine tools.The purpose of this paper is to investigate the effect to the tool by the Electric discharge machining layer.Cutting the cemented carbide before and after the Electric discharge machining with CBN tools carried out,and the influence of the tool angle and tool wear characteristics were examined.The cobalt in the cemented carbide was less,the maximum width of flank wear was bigger.In case of Electric discharge machined materials,the tool life became extremely shorter.When changing the tool angle,the tool angle was in the order of 15 °> 30 °> 60 °,the maximum width of flank wear was increased.
