MC记者:针对黛杰(DIJET)产品,请您谈谈在汽车制造领域的优势在哪里?高永明先生:黛杰(DIJET)刀具在汽车行业中的优势主要分三大方面:第一,主机(发动机)加工线上的钻/铰加工。黛杰在世界上第一个发明了硬质合金钻头,在日本汽车制造厂家以及为其提供设备的机床厂,黛杰几乎成了钻铰加工的代名词。最近推出的“比梦”系列整体烧结金刚石钻头在变速箱销孔的高速加工中一次可加工120000个孔,按照国内大部分发动机厂的产量来说,使用一年也不用更换。 相似文献

为研究PCD刀具高速铣削GH4169合金时刀具的磨损规律,采用单因素试验法分别对不同铣削参数下后刀面磨损程度随切削路程的变化进行对比。结果显示主轴转速对高速铣削GH4169合金时刀具磨损的影响不大,采用顺铣、切削液冷却的方式,并适当降低每齿进给量有助于减小刀具磨损。使用BP神经网络对试验数据进行训练,建立了刀具磨损预测的模型,预测结果与实际结果误差在5%以内。 相似文献

Titanium alloy is a kind of typical hard-to-cut material due to its low thermal conductivity and high strength at elevated temperatures, this contributes to the fast tool wear in the milling of titanium alloys. The influence of cutting conditions on tool wear has been focused on the turning process, and their influence on tool wear in milling process as well as the influence of tool wear on cutting force coefficients has not been investigated comprehensively. To fully understand the tool wear behavior in milling process with inserts, the influence of cutting parameters on tool wear in the milling of titanium alloys Ti6Al4 V by using indexable cutters is investigated. The tool wear rate and trends under different feed per tooth, cutting speed, axial depth of cut and radial depth of cut are analyzed. The results show that the feed rate per tooth and the radial depth of cut have a large influence on tool wear in milling Ti6Al4 V with coated insert. To reduce tool wear, cutting parameters for coated inserts under experimental cutting conditions are set as: feed rate per tooth less than 0.07 mm, radial depth of cut less than 1.0 mm, and cutting speed sets between 60 and 150 m/min. Investigation on the relationship between tool wear and cutting force coefficients shows that tangential edge constant increases with tool wear and cutter edge chipping can lead to a great variety of tangential cutting force coefficient. The proposed research provides the basic data for evaluating the machinability of milling Ti6Al4 V alloy with coated inserts, and the recommend cutting parameters can be immediately applied in practical production. 相似文献

为了优化高温合金GH4169插铣加工过程中的切削参数,采用正交试验法进行高温合金GH4169的铣削试验。基于试验法建立了切削力与切削参数之间的经验公式,分析了各切削参数对切削力的影响规律。运用方差分析法检验了经验公式的显著性。结果表明:F_x、F_y、F_z都随着切削速度V_c、每齿进给量f_z、径向切深a_e的增大而增大;三个方向的切削力受径向切深a_e的影响最大,其次是切削速度V_c,每齿进给量f_z的影响最小,且Z方向切削力F_z大于X、Y方向切削力F_x、F_y。 相似文献

高速车削镍基高温合金GH4169的切削力仿真研究 总被引:1,自引:0,他引:1
基于Deform 3D仿真软件建立了GH4169高温合金高速车削的有限元模型,采用四因素三水平正交试验方法研究了切削用量和刀具几何参数对切削力的影响规律,并建立了切削力经验公式。研究结果表明:在高速车削GH4169的过程中,对切削力影响最大的参数是切削深度,其次是进给量和前角,最后是刀尖圆弧半径;切削力随切削深度和进给量的增大而增大,随前角的增大呈现先降低又升高的趋势,而刀尖圆弧半径增大时切削力变化不大;最佳参数组合为:进给量0.2mm/r,切削深度0.4mm,前角10°,刀尖圆弧半径0.2mm。 相似文献
