摘要：
A spiral micro-milling cutter with micro-texture on the flank is fabricated on a five-axis low-speed wire-cut electrical discharge machining (WEDM) with a rotary mechanism. A theoretical model for cutting force of micro-edge unit of spiral micro-milling cutter with micro-texture was established, and a comparative experiment of micro-textured micro-milling cutter and conventional micro-milling cutter was carried out. The results show that the cutting force of the micro-textured spiral micro-milling cutter is reduced by 30%-40% compared with that of the conventional tool. Under the same processing conditions, the surface roughness of the micro-textured spiral micro-milling cutter is reduced to 0.745 μm, while the surface roughness processed by the conventional micro-milling cutter is 1.130 μm. © 2020, Editorial Department of Journal of Northeastern University.
