摘要
以6061铝合金为研究对象,在高速加工中心上对6061铝合金进行铣削加工,对加工后的工件表面粗糙度、材料去除率以及铣削力进行相应的测量和分析,通过切削加工实验的方法针对不同工艺参数组合方式以及不同刀具材料对加工效率和加工质量的影响情况展开研究,从而确定最优工艺参数组合以及最佳刀具材料。研究结果表明:硬质合金刀具的切削性能优于TIALN涂层刀具,当主轴转速为8000r/min,进给速度为1600mm/min,切削深度为0.2mm时,工件的表面质量最好,表面粗糙度Ra可达到0.14μm,同时材料去除率可以达到46310mm3/min,当主轴转速为8000r/min,进给速度为1600mm/min,切削深度为0.05mm时,铣削力分别是10N(X),11N(Y),7N(Z),该工艺参数组合可以提高刀具耐用度。
In 6061 Aluminum Alloy as the research object,the machining of 6061 Aluminum Alloy in high speed machining center,themachining workpiece surface roughness and material removal rate and milling force measurement and analysis,through the experimental method of machining according to the effects of different methods and different combinations of process parameters on the machining efficiency and tool materials the processing quality of the research,so as to determine the optimal combination of process parameters and the best tool materials.The results show that the cutting performance of TIALN coated tool is better than that of cemented carbide tool,when the spindle speed is 8000r/min,the feed rate is 1600 mm/min,the cutting depth of 0.2mm,the surface quality of the workpiece,the surface roughness Ra can reach 0.14μm at the same time,the material removal rate can reach 46310mm 3/min,when the spindle speed is 8000r/min,feed the speed is 1600mm/min,the cutting depth of 0.05mm,the milling force is 10N(X),11N(Y),7N(Z),so as to prolong tool life,improve the tool endurance.
