摘要/Abstract

摘要： 基于五轴低速走丝电火花线切割机床与回转机构相结合的加工方法，制备了后刀面具有微织构的螺旋微铣刀.建立了微织构螺旋微铣刀微刃单元的切削力理论模型，并开展微织构微铣刀与常规微铣刀的对比实验研究.结果表明:微织构螺旋微铣刀的切削力相对于常规刀具降低了30%~40%，相同加工条件下，微织构螺旋微铣刀所加工的表面粗糙度降低至0.745μm，而常规微铣刀所加工的表面粗糙度为1.130μm.

Abstract: 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 0.745μm， while the surface roughness processed by the conventional micro-milling cutter is 1.130μm.

Key words: electrical discharge machining (EDM), wire cut, micro texture, micro milling cutter, micro milling
