Energy Dissipation in the Ultraprecision Machining of Copper

Effect of finite edge radius on ductile fracture ahead of the cutting tool edge in micro-cutting of Al2024-T3

“…This experimental study showed that the nominal rake angle and the tool edge profile significantly affect the forces. In another experimental study [21], it was seen that at lower uncut chip thickness values closer to the tool edge radius, the energy consumed in the shear zone alone was unable to account for the size effect in specific cutting energy. This anomaly was attributed to sliding at the tool-work interface and ploughing.…”

Fundamentals of Micro‐Manufacturing

“…The chips will be generated, and material removal will be achieved only when the uncut chip thickness reaches a critical value, the so-called minimum chip thickness [69]. Minimum (or critical) uncut chip thickness is considered to be a measure of the highest attainable accuracy [70,71]. No chip is produced with a chip thickness less than a critical value, and the entire material is forced under the cutting tool and deformed.…”

Cutting force model considering tool edge geometry for micro end milling process

“…The contact length l C was obtained from the relief angle of the tool and the spring back due to the elastic recovery occurring on the flank face by Arcona and Dow's model [12]. The contact length l C can be ob- tained with the following Eq.…”
