1. Ka horoia te mekameka i mua i te ine
2. Tākaihia te mekameka kua whakamatautauria ki ngā porotiti e rua, ā, me tautoko ngā taha o runga me raro o te mekameka kua whakamatautauria.
3. Me noho te mekameka i mua i te ine mō te 1 meneti i raro i te āhua o te whakamahi i te hautoru o te kawenga kume mutunga iti rawa.
4. I te wā e ine ana, whakamahia te kawenga ine kua tohua ki runga i te mekameka, kia kukū ai ngā mekameka o runga me o raro. Me whakarite te mekameka me te porotiti kia tika te niho.
5. Inehia te tawhiti i waenga i ngā pokapū o ngā porotiti e rua 1. Hei tango i te āputa o te mekameka katoa, me ine i raro i tētahi taumata o te kumenga i runga i te mekameka.
2. I te wā e ine ana, hei whakaiti i te hapa, inehia i te 6-10 knots (hononga)
3. Inehia te rahi o roto o te L1 me te rahi o waho o te L2 i waenganui i te maha o ngā roera hei whiwhi i te rahi whakatau L=(L1+L2)/2
4. Kimihia te roa o te mekameka, ka whakaritea tēnei uara ki te uara rohe whakamahi o te roa o te mekameka i te tūemi o mua.
Te roa o te mekameka = te rahi o te whakatau – te roa tohutoro / te roa tohutoro * 100%
Roa tohutoro = teitei mekameka * tau o ngā hononga Ko te mekameka roera tuku paerewa he mekameka roera tuku whānui e hangai ana ki ngā paerewa JIS me ANSI. 2. Ko te mekameka rau he mekameka iri e titoa ana ki ngā pereti mekameka me ngā toki titi. 3. Ko te mekameka kowiri tira he mekameka kowiri tira ka taea te whakamahi i roto i ngā taiao motuhake pēnei i te rongoā, te wai me te pāmahana teitei. 4. Ko te mekameka ārai-waikura he mekameka me te whakakikorua nikara i te mata. 5. Ko te mekameka tāpiri paerewa he mekameka me ngā taputapu tāpiri i runga i te mekameka roera paerewa mō te tuku. 6. Ko te mekameka toki titi tuwhera he mekameka e honoa ana e te toki titi tuwhera. E ai ki ngā hiahia o ngā kiritaki, ka taea te tāpiri, te tango rānei i te toki titi, te pae whakawhiti me ētahi atu taputapu. 7. Ko te mekameka roera takirua-teitei (momo A) he mekameka e rua te teitei o te mekameka roera paerewa e hangai ana ki ngā paerewa JIS me ANSI. He mekameka tuku tere-iti me te roa toharite me te taumaha mama, ā, he pai mō ngā tāutanga me ngā tawhiti roa i waenga i ngā toki. mekameka tawhiti. , e whakamahia ana mō te tuku me te whakahaere tere-iti, me ngā roera momo-S te diameter paerewa me ngā roera momo-R te diameter nui. kawe. 10. Ko te mekameka roera momo ISO-B he mekameka roera e ahu mai ana i te ISO606-B. He maha ngā hua i kawemai mai i Peretānia, Wīwī, Tiamana me ētahi atu wāhi e whakamahi ana i tēnei momo.
