在刀具设计、制造及检验中,不仅要知道(标注)主剖面系的角度,而且还要知道(标注)法剖面系的角度,这就要进行主、法剖面间的角度换算。其换算公式如下: 前角换算公式: tgγ_n=tgγ_0·cosλ_s (a) 后角换算公式: tgα_0=tgα_0/cosλ_s (b) 式中:γ_0、γ_n——主、法剖面的前角(度) α_0、α_n——主、法剖面的后角(度) In the tool design, manufacture and inspection, not only the angle of the main section system, but also the angle of the section system should be known. Therefore, the angle between the main section and the cross section should be converted. The conversion formula is as follows: anterior horn conversion formula: tgγ_n = tgγ_0 · cosλ_s (a) The relief angle conversion formula: tgα_0 = tgα_0 / cosλ_s (b) Where: γ_0, , Α_n - the main, law section of the back angle (degrees)
