【摘要】 采用犁切—挤压一次成形加工工艺,在0.5mm厚的铜带表面加工出V形毛细微沟槽结构。对所加工的V型微沟槽进行电镜扫描,观察其特征,并用显微镜测量其几何参数。分析了不同加工参数和刀具结构参数对沟槽翅高和槽深度的影响。研究结果表明:在V型微沟槽成形过程中,受到加工参数和刀具结构参数的联合影响。更多还原

【Abstract】 The plough-extrusion direct forming technology is proposed to machine different tiny V form grooves in the copper surface.The copper’s thickness is 0.5 mm.The characteristic of the tiny V form grooves is observed with SEM,and its geometry parameter is measured with microscope.The effects of different machining parameters and structure parameters to fin height and groove depth are analyzed.The experimental results show that a tiny V form groove formation process is affected associated by the machining parameter and the structure parameter.更多还原
