Experimental study on grinding force in axial feed grinding of cemented carbide with diamond grinding wheel

  • 摘要: 为研究金刚石砂轮轴向进给磨削硬质合金时的磨削力,建立轴向力与法向力、切向力的转化模型;测量不同工艺参数下的磨削力变化;分析工艺参数对法向力、切向力、轴向力的影响规律并建立磨削力的经验公式。结果表明:在轴向进给磨削过程中,最大的磨削力是法向力,而轴向力略小于切向力。砂轮线速度对3个方向的磨削力的影响大致相同。磨削深度对法向、切向及轴向3个方向的磨削力的影响明显不同。进给速度对3个方向磨削力的影响不显著。
