Haunga ngā whakaritenga tika o te poraka anaro i roto i ngā wāhanga o te taputapu tirotiro waka, ka whakamanahia te tika o te teitei o ētahi atu wāhanga kia tāpiri, kia tango rānei.±0.01MM, ā, ka taea te āhua i roto i te awhe tāpiri, tango rānei i te 0.1mm. Ina whakamahia te tikanga pātene, ka tukatukahia hoki kia rite ki te paerewa tāpiri, tango rānei i te 0.1 mm me te teitei kia rite ki te manawanui tāpiri, tango rānei i te 0.01 mm.

E toru ngā wāhanga o te tikanga tukatuka o te whitiki taputapu tirotiro waka, ko te nohoanga whitiki me te whitiki maui me te whitiki matau ōrite. I mua i te tukatuka, ka whakatauhia tuatahitia te rauemi o te rauemi e haere mai ana, kātahi ka whakatauhia te āhua o waho o te rauemi e haere mai ana, mēnā he 0.3 ~ 0.5mm.Ka tīmata te wero i te nui o te mīhini mira. Hei whakahaere i te tukatuka i muri mai, me hanga te pūwāhi tohutoro. Ka mīhinihia te kōhao titi tūnga ki te mata wiri 2.5mm. Me tapahi te kōhao titi, ā, me whakaoti i muri i te otinga o te huri. Kia oti te mīhini mira, ka tukuna te pato. Ko te maimoatanga wera, ko te pakeke he HRC45.° C ~ 48° C, kāore ngā herenga paerewa i tonoa i te mākete i whakapakeketia, Hei whakaaro ki te roa o te ora o ngā wāhanga, ka whakapakeketia ngā wāhanga maitai katoa, ā, ka oti i muri i te maimoatanga wera. Kia mahara ko te matotoru o te nohoanga hopu me te poraka whitiki me whakapai ake kia±0.01MM, ā, ka oti te tukatuka tapahi waea i muri i te otinga. Ko te awaawa me te kōhao kati ngā mea tuturu. I te wā e taurite ana, me aro koe ki te āputa taurite. Kia kore ai e taea te whakangaueue i te taha maui me te taha matau i muri i te otinga o te mahi tahi, ka oti he tikanga kati tino pai.
