Cutting edge radius
WebThe designed cutting edge radius (CER) from 4 up to 15 mu m is prepared by drag finishing (DF). The results have indicated that the CER are remarkably significant on the cutting performances. With the CER increased from 4 to 15 mu m, the cutting force F-c and feed force F-f increased 23% and 56% at uncut chip thickness h = 0.2 mm, … WebThe cutting edge radius of a micro-milling tool is approximately 1–20 μm , which is about in the same magnitude as it is used at the conventional sized tools. The value of the cutting edge radius depends mainly on the material of the tool, the particle size, the manufacturing precision and the state of tool wear .
