بيت /effect of speed in ball milling
In order to solve the problem of machined surface damage and machining efficiency decline that caused by the decrease of effective cutting thickness in high speed ballend milling hardened steel, using high speed cutting adiabatic shearing model, analyzed the adiabatic shearing deformation on hardened steel, and proposed the criterion of chip separating position.

Effects of cutting conditions on forces and force coefficients in plunge milling operations Francesco Rafanelli, Gianni Campatelli and Antonio Scippa Abstract The modeling of milling forces is a crucial issue to understand milling processes. In the literature, many force models and experiments to identify force coefficients are found.
