② Fumana selikalikoe (D) ho tloha ka lehlakoreng le leng la sekoere (S surface)
D=1.414S lehlakoreng le fapaneng×1.414
9. Liforomo tsa lipalo bakeng sa mahlakore a fapaneng a lisekoere le li-angles tse fapaneng ka mokhoa o batang oa lihlooho
① Fumana angle e fapaneng (e) ho tloha lehlakoreng le leng (S) la lisekoere tse kantle
e=1.4s ke lehlakore le fapaneng (ma)×1.4 paramethara
② Fumana lehlakore le fapaneng (e) la lehlakore le fapaneng (ma) la lisekoere tse ka hare
e=1.45s ke lehlakore le fapaneng (ma)×1.45 coefficient
10. Foromo ea ho bala molumo oa Hexagon
s20.866×H/m/k e bolela lehlakore le fapaneng×lehlakoreng le fapaneng×0.866× bophahamo kapa botenya.

13. Foromo ea lipalo bakeng sa litekanyo tsa machining tsa lipompo tsa khoele tse ka hare
1. Palo ea pompo e kholo bophara ba D0
D0=D＋(0.866025P/8)×(0.5~1.3) ke boholo ba motheo ba khoele e kholo ea bophara ba pompo + 0.866025 pitch÷8×0.5～1.3.
Tlhokomeliso: Khetho ea 0.5 ~ 1.3 e lokela ho khethoa ho latela boholo ba molumo. Ha boleng ba molumo bo le boholo, coefficient e nyane e lokela ho sebelisoa. Ka lehlakoreng le leng, ha boleng ba molumo bo le nyane, coefficient e tsamaellanang e lokela ho ba kholoanyane.
2. Palo ea bophara ba pompo ea molumo (D2)
D2=(3×0.866025P)/8, ke hore, tap diameter=3×0.866025×pitch÷8
3. Palo ea bophara ba pompo (D1)
D1=(5×0.866025P)/8 ke bophara ba theipi=5×0.866025×pitch÷8
leshome le metso e mene,
Palo ea palo ea bolelele ba thepa bakeng sa sebopeho sa lihlooho tse batang tsa libopeho tse fapaneng
Foromo ea molumo oa selikalikoe se tsebahalang ke bophara× bophara×0.7854× bolelele kapa radius×radius×3.1416× bolelele. Ke hore, d2×0.7854×L kapa R2×3.1416×L
Ha u bala, molumo oa X÷diameter÷diameter÷0.7854 kapa X÷radius÷radius÷3.1416 ea thepa e hlokahalang ke bolelele ba boitsebiso.
Foromo ea kholomo = X/(3.1416R2) kapa X/0.7854d2
Ka foromo, X e emela boleng ba molumo oa thepa e hlokahalang;
