Indlela yokucubungula umphetho ocinezelweyo
1. Nje ukuba umphetho utyunyuzwe
Indlela yokucinezela umphetho ongapheliyo ngexesha elinye: Okokuqala, songa ipleyiti ibe ngama-30 degrees ngemela yokugoba engama-30 degrees, uze emva koko ugobe umphetho ngendlela ethe tyaba.
2. Ukugoba ngeedigri ezili-180:
Indlela yokugoba ngeedigri ezili-180: Okokuqala songa ipleyiti ibe ziidigri ezingama-30 ngemela yokugoba yeedigri ezingama-30, uze uyicande umphetho wokugoba, uze ukhuphe ipleyiti engasemva.
Umlinganiselo olinganiselweyo womda ongapheliyo
a) Umphetho ongasekhoyo kufuneka ugotywe kabini. Okokuqala, goba ngama-30 ° ~ 45 ° ngemela ebukhali engama-30 ° kunye nomjelo onzulu we-V, uze ucinezele ucaba ngedayi ethe tyaba. Uluhlu lomphetho ongasekhoyo onobukhulu obahlukeneyo bezinto: 0.5 < T < 2.0
b) Ubude (L) bomphetho ocinezelweyo bunxulumene nobukhulu bezinto kunye nobunzulu bokufakwa kwe-groove ye-V. Xa i-0.5 < T ≤ 1.5, kukhethwe i-groove yokufaka ye-V6, kunye ne-L min > 5T + R (L min > 6); Xa i-2.0 ＜ T < 2.5, khetha i-V10 ukufaka i-groove enzulu, i-L min ≥ 5T + R (L min > 9); Ubude bomphetho ongasekhoyo u-L max kwezi zimbini zingasentla yi-≤ 14mm
c) Ubude L bomphetho ocinezelweyo emva kokugoba umva bunqunyelwe bubunzulu bokufakelwa kwe-V groove, L min ≥ 11mm
d) Umgama ukusuka kumngxuma ongasecaleni ukuya kumda wokugoba akufuneki ube mncinci kakhulu, kungenjalo umngxuma uya kuphazamiseka kukutshintsha kwe-engile ngexesha lokugoba: l1min > 0.7V
