    Abstract: Experimental milling of Al alloy was performed to
    compare single edge rhombus micro-end mills. The
    purpose was to examine how various control factors
    affect tool wear. Examined control factors included
    coating layer, side clearance angle, feed rate and spindle
    speed. Taguchi method was applied to rapidly derive an
    experimental optimum combination of cutting
    parameters. During the milling test, depth of cut was
    fixed at 0.2 mm and width of cut at 0.50 mm to explore
    correlations among side clearance angle, feed rate,
    spindle speed and coating layer. Upon completing each
    milling test, the cutting-edge wear and flank wear were
    measured offline by the aforementioned tool
    microscope. The experimental results showed that,
    among the four control factors, side clearance was the
    most important factor in tool wear. Using TiCN-coated
    drill bits and setting side clearance angle at 12 degrees,
    spindle speed at 6000 rpm and feed rate at 0.0125
    mm/rev minimized the wear on micro-end mills and
    maximized tool life.
