Abstract
In the present paper succeeded to the previous ones, was discussed the relation between the machining energy E and the machining speed W. The machining speed is influenced by both the working efficiency of the abrasive grains and the pumping action. The pumping action has the relation with the magnitude of the tool's amplitude and also it operates efficiently to remove the chips machined. The theoretical formulae showing the machining speed are given in the next expressions, and these formulae are confirmed to have a good agreement with the results given by the experimental study.
when |ν0|≤|νL|, W= [1/8·Kη·F02 (1-γ2)/(mf)]/[1+1/8·Kη·F02 (1-γ2)/γf (ζV+V0)log{(ζV+V0)/V0}], and when|ν0|≥|νL|, W = [1/2·KηmfνL2]/[1+1/2·KηmνL2/γ(ζV+V0)log{(ζV+V0) /V0}].
