Experimental Investigation of Influencing Factors of Surface Roughness Engraved by CNC Engraving Machine

Abstract:

Takes aluminum alloy ZL301 as an example, gets different surface roughness and cutting time under different cutter rotate speed and different overlapping rate with CNC engraving technique and analyses the reasons. The result is that the more of overlapping rate, the more cutting time, and the less of the surface roughness. While the overlapping rate≥50%, the roughness Ra≤6.3μm, while the overlapping rate≥70%, the cutting time increasing obviously. Consider the efficiency and the surface roughness, the best overlapping rate is from 50%～70%. The more of cutter rotate speed, the less of the surface roughness. While the overlapping rate≤70%, the cutter rotate speed almost no influence to the cutting time.
