中文摘要:
      螺旋槽丝锥结构复杂,刀具寿命较短,为了研究螺旋槽丝锥的切削性能,对螺旋槽丝锥进行受力分析,建立丝锥 的力学模型。用SolidWorks建立螺旋槽丝锥的三维模型,用仿真软件AdvantEdge FEM模拟螺旋槽丝锥攻丝过程;采用 正交试验法分析HSS-Co-PM ASP2030高速钢螺旋槽丝锥加工AISI-4/30合金结构钢时的切削性能;利用极差分析法研究 螺旋槽丝锥几何参数端面前角γp、切削锥角,kr、沟槽螺旋角w对切削力的影响。试验结果表明:沟槽螺旋角对切削力的 影响最大,其次是端面前角和切削锥角。螺旋槽丝锥加工合金结构钢取沟槽螺旋角35°,切削锥角12°,端面前角2°时切 削力最小,能有效提高刀具寿命
英文摘要:
      Spiral fluted tap's structure is complex, and the tool life is short. In order to analyze the cutting of spiral fluted tap , the mechanical model was built by analyzing the force of spiral fluted tap. The three-dimensional model of the spiral fluted tap was established by SolidWorks. The tapping process of spiral fluted tap was simulated by AdvantEdge FEM. Alloy structural steel AISI-4/30 was tapped with the HSS-Co-PM ASP2030 by the orthogonal test method. The impact of the end face rack angle,the chamfer angle and the spiral flute angle on cutting force were studied by extreme difference analysis. The results indicate that the influence of spiral flute angle is the maximum, and the chamfer angle is the smallest. The optimal geometric parameters are that, the spiral flute angle is 350, and the chamfer angle is 120,and the end face rack angle is 20.
