【摘要】：目的研究Ta-C涂層刀具與普通類金剛石涂層刀具切削2A50鋁合金時(shí)的性能對(duì)比。方法通過(guò)實(shí)驗(yàn)比較兩刃、四刃Ta-C涂層銑刀和兩刃、四刃普通類金剛石涂層銑刀,在干式切削條件下切削2A50鋁合金的性能。通過(guò)相同切削條件下刀具切削距離的長(zhǎng)短,比較刀具的使用壽命,并在顯微鏡下觀察切屑的表面形貌,用表面粗糙度儀檢測(cè)鋁合金表面的粗糙度。結(jié)果兩刃Ta-C涂層銑刀干式切削鋁合金時(shí)的使用壽命最長(zhǎng),切削距離為116 m。Ta-C涂層銑刀與普通類金剛石涂層銑刀加工工件的表面粗糙度總體呈上升趨勢(shì),兩刃Ta-C涂層銑刀加工出來(lái)的工件表面質(zhì)量較好,工件表面粗糙度均值為0.692μm。結(jié)論相同刀刃數(shù)量且結(jié)合力良好的涂層銑刀相比較,Ta-C涂層銑刀較普通類金剛石涂層銑刀加工出來(lái)的工件表面粗糙度平均值低,同種涂層加工得到的切屑表面微觀形貌無(wú)明顯差別。Ta-C涂層銑刀與普通類金剛石涂層銑刀切削鋁合金時(shí),抑制粘刀效果都十分明顯,但Ta-C涂層銑刀效果更優(yōu)。
[Abstract]:Objective to study the performance comparison between Ta-C coated tool and common diamond-like carbon coated tool in cutting 2A50 aluminum alloy. Methods the performance of two-edge, four-edge Ta-C coated milling cutter and two-edge, four-edge common diamond-like carbon coated milling cutter for cutting 2A50 aluminum alloy under dry cutting conditions were compared experimentally. Through the length of cutting distance under the same cutting condition, the service life of the cutting tool is compared. The surface morphology of the chip is observed under microscope, and the roughness of aluminum alloy surface is detected by surface roughness meter. Results the service life of two-edge Ta-C coated milling cutter for dry cutting aluminum alloy is the longest. The cutting distance is 116 m.Ta-C coated milling cutter and the common diamond-like carbon coated milling cutter has a rising trend of surface roughness. The surface quality of the workpiece machined by two-edge Ta-C coating milling cutter is better, and the average surface roughness of the workpiece is 0.692 渭 m. Conclusion compared with the coated milling cutters with the same number of edges and good adhesion, the surface roughness of Ta-C coated milling cutters is lower than that of ordinary diamond-like carbon coating milling cutters. There is no obvious difference in the micromorphology of the chip surface obtained by the same coating processing. When cutting aluminum alloy with Ta-C coated milling cutter and ordinary diamond-like carbon coating milling cutter, the effect of restraining stick cutter is obvious, but the effect of Ta-C coating milling cutter is better than that of conventional diamond-like coating milling cutter.
