ここで、vfは、振動なしの送り速度(例えば、mm/分)であり、aは、1回転当たりの軸方向送り速度(例えば、mm/1回転)であり、fwはワークピースの回転数(回転/秒)である。
h(t)=vfT/n+2A{cos[Πfm(2t-T/n)]sin[Π(fm/n)T]}
h(t)=a/n+2A[cos(2Πfmt−Π(fm/n)fw)][sin(Π(fm/n)/fw)]
ここで、fwは、ワークピースの回転速度(回転/秒)であり、Tは、ワークピースの1回転期間=2Π/ωw=1/fwであり、nは、切削工具エッジ数であり、vfは、振動なしの送り速度(mm/秒)であり、fmは、サイクル/秒(Hz)における振動周波数(ωm=2Πfmrad/秒))であり、Aは、振動の振幅の1/2(mm)であり、tは、時間(秒)である。
ここで、fCBは、ワークピース1回転毎のチップの切断頻度(切断/1回転)である。
ここで、TCBは、1振動周期の切断継続時間(h=0の場合の数値解による時間値)であり、Lは、おおよそのチップ長さ(mm)であり、fwは、ワークピースの回転数(回転/秒)である。
ここで、rは、ワークピースの半径(例えば、mm)である。
Vcm=Vc−2ΠfmAsin(2Πfmt)
ここで、vcは、振動を伴わない場合の切削速度(mm/秒)であり、fmは、振動周波数(サイクル/秒,Hz)であり、fwは、ワークピースの回転周波数(回転/秒,Hz)である。Aは、振動の最大(ピーク−ピーク)振幅の1/2であり、tは、時間(秒)である。
