Investigation on the ploughing force in microcutting considering the cutting edge radius
The International Journal of Advanced Manufacturing Technology, 2016Ploughing force is a parasitic force induced by the blunt cutting edge and the contact at flank face. Investigation on the ploughing force is necessary for the cutting mechanism understanding, the tool wear monitoring, and the tool sharpness evaluation.

Observations on cutting edge radius effects in cryogenic machining of porous tungsten
2015 IEEE International Vacuum Electronics Conference (IVEC), 2015Porous tungsten is a refractory metal commonly used to manufacture dispenser cathode pellets. To produce the required geometric shape of a cathode, precision machining of the emitting surface is necessary. Because dry machining leads to excessive tool wear and smearing of surface pores, a plastic infiltrant is used to both prevent smearing and ...

An experimental study of edge radius effect on cutting single crystal silicon
The International Journal of Advanced Manufacturing Technology, 2003According to the hypothesis of ductile machining, brittle materials undergo a transition from brittle to ductile mode once a critical undeformed chip thickness is reached. Below this threshold, the energy required to propagate cracks is believed to be larger than the energy required for plastic deformation, so that plastic deformation is the ...

Calculation of length, height, and radius of edge buildup on cutting tools
Journal of Superhard Materials, 2007The available cutting theory models and formulas for calculating the dimensions of contact areas on tool faces are discussed. Based on rheological properties of materials and some laws of the cutting theory, a generic mathematical model has been developed for the determination of edge buildup dimensions.
