摘要: Abstract We have investigated the cutting forces, tool wear and surface finish obtained in high speed diamond turning milling of OFHC copper, brass CuZn39Pb3, aluminum AlMg5, electroless nickel. In face experiments with constant material removal rate forces were recorded as a function between v c = 150 m/min 4500 m/min revealing transition to adiabatic shearing which is supported by FEM simulations process. Fly-cutting carried out at low (v = 380 m/min) = 3800 m/min) showed that abrasive edge significantly higher ordinary than contrast experience made conventional machining. Furthermore, it was found chemically induced steel decreasing engagement time per revolution. High machining may also yield an improved roughness confirmed comparing step heights grain boundaries copper CuZn39Pb3 = 100 m/min) = 2000 m/min). Thus, offers several advantages, let alone major reduction time.
