摘要：采用正交试验方案，应用(Ti，Al)N+TiN涂层硬质合金刀具对GH2132铁基高温合金进行外圆干切削，测量了切削力、切削温度、表面粗糙度和刀具寿命。利用最小二乘法对试验数据进行了多元回归分析，分别建立其经验公式，并分析了切削用量三要素分别对切削力、切削温度、表面粗糙度和刀具寿命的影响规律及其原因。通过试验得出了切削用量三要素分别对其影响的主次顺序。切削力：ap>f>vc，切削温度：vc>ap>f，表面粗糙度：f>vc>ap，刀具寿命：vc>f>ap。

Abstract:The dry cutting tests with (Ti，Al)N+TiN coated carbide tools are done on ironbased superalloy GH2132 by orthogonal experiment method for obtaining information on cutting force，cutting temperature，surface roughness，tool life.Theirempirical formulas are established by multivariate regression analysis with least square method，and influence laws on cutting force，cutting temperature，surface roughness，tool life are studied.The tests show that the order in which cutting parameters affects them is as follows，cutting force:ap>f>vc，cutting temperature:vc>ap>f，surface roughness:f>vc>ap，tool life:vc>f>ap.
