滾牙徑的速算法
提供一個滾牙徑(還沒滾牙的直徑)的速算法供大家分享
  D=公稱直徑尺寸 P=牙距 d=滾牙徑 
  X=0.05~0.3依螺紋密合度(M2~M12一般約0.1)
    (標準牙峰60度角常數0.6495)

    d=D-X-(P*0.6495)

例: M6-P1.0滾牙徑=6-0.1-0.6495=5.25mm
    M20-P1.5     =20-0.2-(1.5*0.6495)=18.82mm
    M5-P0.5      =5-0.05-(0.5*0.6495)=4.62mm
    M1.2-P0.25   =1.2-0.05-(0.25*0.6495)=0.987mm

讓專業的來
輾芽膨脹係數為0.6
這樣算可能會比較快
