Ahau.Te Whakarite Whakamātautau
1. Kaua e iti iho i te 8 ngā wā o te hohonutanga o te kōhao (te tikanga ≥10mm) te matotoru o te tauira kua whakaritea kia kaua e uru te kōhao ki roto i te tauira, kia kore rānei e pāngia e te tautoko o te mata o raro.
2. Kia mau ki ngā karapu tiaki i te wā e whakamahi ana koe hei karo i te pa tika o ngā maihao ki te mata o te tauira, ka pā pea te poke, te karawarawa rānei.
3. Mena me wehewehe ngā tauira rerekē, tohua ngā tau rangatū ki te mata kāore i te whakamātautauhia hei ārai i te pokanoa ki te wāhi kōhao.
4. Me whakarite kia ōrite te rauemi tauira ki te rauemi whakatō (hei tauira, me whakamahi he whakatō tungsten carbide mō ngā rauemi pakeke) kia kore ai e nui rawa te kakahu o te whakatō, e pakaru rānei te tauira.
II. Ngā Tukanga Whakahaere
1. Te Whakaoho Taputapu me te Whakamātautau-ā-Iho
I muri i te whakaū kua tika te hononga o te taura hiko o te taputapu, monohia ki te putanga hiko 220V, 50/60Hz, kātahi ka tahuri te pana hiko o muri. Ka whakamātautau-ā-koe te taputapu, ka tiaho te mata whakaatu, ka whakaatu i te atanga tuatahi. I muri i te otinga o te whakamātautau-ā-koe, ka tautuhi aunoa te taputapu, ka uru ki te āhua tūtatari mō te mahi.

2. Tāutanga me te Whakatūnga o te Indenter
I runga i ngā āhuatanga o te rauemi e whakamatautauria ana, tīpakohia he kōhao poroporo karāhe kua whakakikoruatia ki te sima, he rahi e tika ana (φ2.5, 5, 10 mm). Horoia te hinu ārai-waikura ki te waipiro, ka murua kia maeneene ki te kakahu miro ma. Whakauruhia te kōhao ki roto i te kōhao porowhita, ka hurihia te tīwiri whakapiri kia uru ki te wāhanga papatahi o te kakau kōhao, kia mau ai te tāutanga. Kātahi ka tīpakohia he tūāpapa whakamātautau (tūāpapa papatahi nui, tūāpapa papatahi iti, tūāpapa āhua-V) kia rite ki te āhua o te tauira, whakatakotoria te tauira kia mau, kia piri hoki, ā, kia mārama te mata, kia kore he poke.
3. Te Kōwhiringa me te Tautuhinga o te Kaha Whakamātautau
Ka whakaratohia e te Kaiwhakamātautau Pakeke Hiko Brinell HB-3000C ngā taumata 10 o ngā kaha whakamātautau tika (mai i te 612.9 N ki te 29421 N). Ka taea e te kaiwhakahaere te whiriwhiri i te taumata kaha e hiahiatia ana i runga i te mata pa 8-inihi kia rite ki ngā whakaritenga whakamātautau, ā, ka whirihora aunoa te kaiwhakamātautau i ngā taumaha kia tutuki ai te kaha whakamātautau kua whakaritea.
I taua wā, ka taea te whakarite i te wā noho i runga i te mata pa mai i te 0 ki te 60 hēkona i runga i ngā āhuatanga o te rauemi. Mō ngā rauemi whānui, ko te wā noho e taunakitia ana ko te 10–15 hēkona.
4. Whakamātautau Pakeke Brinell
Whakatakotoria te mea mahi ki runga i te tēpu mahi, ka huri i te wira ringa ki te taha matau i te tere pumau me te ōrite hei whakaara ake i te taumata tauira. Kati tonu te huri ina tangi te pī ina pā te tauira ki te pūwero.
Ka tīmata aunoa te whakamātautau e te kaiwhakamātautau, tae atu ki te whakamahi, te pupuri, me te tango i te kaha matua o te whakamātautau kia puta he kōhao. Kātahi ka hurihia te wira ringaringa ki te taha maui hei whakaheke i te taumata tauira me te tango i te tauira kua whakamatautauria.
5. Te Ine i te Pakari o te Brinell
Tangohia te tauira, ka kitea he kōhao porowhita i runga. Inehia te diameter kōhao mā te whakamahi i te karuārai ine 20×, kātahi ka whakauru i te uara ine ki te panera o te taputapu Whakamātautau Pakari Brinell hB-3000C. Ka tatau aunoa te pūnaha i te uara pakeke i runga i te tātai kua whakaritea.
Heoi anō, kei te wātea he pūnaha ine Brinell whiriwhiri. Ka hopukina e tēnei pūnaha te ahua o te kōhao mā te pūoko CCD, ā, ka inehia aunoatia te uara pakeke, ka whakaaturia hoki e te rorohiko.
6. Te Tuhi Raraunga me te Whakaputa Pūrongo
Kia oti te whakamātautau, ka taea e te kaiwhakahaere te tiro i ngā raraunga taipitopito i runga i te mata pa, tae atu ki ngā uara pakeke, ngā diameter kōhao, me ngā mōhiohio tatauranga (te uara mōrahi, te uara iti rawa, te uara toharite, me ētahi atu). Ka taea te tiaki i ngā raraunga ki te mahara o roto o te kaiwhakamātautau, ki tētahi pūrere rokiroki USB o waho rānei.
Hei tāpiritanga, ka taea e te pūmanawa whakamātautau te whakaputa aunoa i tētahi pūrongo Word kei roto ngā raraunga ine, ngā hua tatauranga me ngā whakaahua, ka taea te tā, te kaweake rānei e te kaiwhakamahi.
III.Te Tiaki me ngā Whakatūpato
1. Kia oti te whakamātautau, tukuna ngā kaha katoa o te whakamātautau, tīpakohia te kōwhiringa whakaweto i te mata pā, ka whakaweto i te pana mana o te taputapu.
2. Ki te kore te taputapu e whakamahia mō te wā roa, momotuhia te taura hiko, tangohia ngā wāhanga pēnei i te kōhao me ngā taumaha, horoia rawatia, ā, rongoatia kia tika ki ngā wāhi kua tohua hei ārai i te kino, i te ngaronga rānei.
3. Me horoi me te tiaki i ngā taputapu i ia wā. Tirohia te āhua o te pakaru o ngā wāhanga tae atu ki te pūwero me ngā taumaha, ā, whakakapia ngā wāhanga kua pakaru, kua tino pakaru rānei i te wā tika. Kia ma, kia maroke hoki te taiao mahi o ngā taputapu kia kore ai e pakaru i te puehu, i te makuku, i ētahi atu poke rānei.
4. Mauria ngā taputapu tiaki e tika ana (hei tauira, ngā mōhiti tiaki me ngā karapu tiaki) i te wā e mahi ana hei ārai i ngā whara whaiaro mai i ngā aituā.
5. Whakahaerehia ngā taputapu kia rite tonu ki ngā whakaritenga whakahaere. Kaua e whakarerekē noa i ngā tautuhinga tawhā, i ngā tikanga whakahaere rānei o te taputapu, kia tika ai, kia pono ai hoki ngā hua whakamātautau.
6. Mēnā ka hē te mahi a te taputapu, ka rerekē rānei te āhua, kati tonu te mahi ka momotu te pūtake hiko, kātahi ka whakapā atu ki ngā kaimahi tiaki ngaio mō te tirotiro me te whakatika.
