Te Tūranga me te Whakarōpūtanga o ngā Poraka Mārō i roto i te Whakamātautau Whakamātautau Mārō

I roto i te tukanga whakamātautau pakeke, he mea nui ngā poraka pakeke paerewa. Nā, he aha te mahi a ngā poraka pakeke, ā, me pēhea te whakarōpūtanga?

I.E toru ngā mahi matua a ngā poraka pakeke i roto i te whakamātautau pakeke: te whakatikatika i ngā taputapu whakamātautau pakeke, te whakahohe i te whakatairite raraunga, me te whakangungu i ngā kaiwhakahaere.

1. I te whakamahinga roa o te taputapu whakamātautau pakeke, ka puta pea ngā huringa ki ngā pūoko, ki te hanganga mīhini rānei o te mīhini. Nō reira, ka whakamahia e mātou ngā poraka paerewa kua tohua ki ngā uara pakeke e mōhiotia ana hei manatoko, hei whakatika rānei i te tika o te taputapu whakamātautau pakeke. Kua tohua ia poraka pakeke ki tētahi uara pakeke; mā te whakamātautau ki te poraka pakeke i mua i te kitenga ōkawa ka taea te whakatikatika i te uara tohu o te taputapu whakamātautau pakeke, te whakakore i ngā hapa o te taputapu, te whakarite kia tutuki ngā raraunga ine i ngā whakaritenga paerewa, te manatoko i te pumau o te mahi a te taputapu whakamātautau pakeke, me te whakatau wawe mēnā kei roto te taputapu whakamātautau pakeke i te āhua mahi noa.

2. Mā te whakatikatika i ngā poraka pakeke me ngā whakaritenga kotahi, ka taea te whakataurite i ngā hua whakamātautau i waenga i ngā kaiwhakamātautau pakeke rerekē me ngā kaitirotiro rerekē. Mā te whakarato i ngā tohutoro paerewa me ngā uara pakeke e mōhiotia ana, ka kotahi ngā paerewa whakamātautau i raro i ngā kaiwhakamātautau pakeke rerekē me ngā āhuatanga ine rerekē.

3. He mea noa hoki te whakamahi i ngā poraka pakeke paerewa i roto i ngā whakangungu kaimahi i roto i ngā taiwhanga, i ngā wheketere rānei hei whakapai ake i te matatau mahi.

Ka whakatauritea ō rātou uara pakeke e ngā umanga whai mana, e whakaatu ana i te āheinga ki te whai, te tika, me te pumau. He rite te rauemi o ngā poraka pakeke ki te rauemi e whakamatautauria ana (pēnei i te konganuku, te kirihou, me ētahi atu), ka taea te whakataurite ki ngā tikanga ine pakeke rerekē (Brinell, Rockwell, Vickers, me ētahi atu).

Tuarua.Ko te whakarōpūtanga o ngā poraka pakeke e ahu mai ana i ngā tauine pakeke rerekē, ngā momo rauemi, me ngā awhe uara pakeke. Ko ngā momo noa e whai ake nei:

1. Whakarōpūtanga mā te Tikanga Ine Pakeke

Koinei te tikanga whakarōpū e whakamahia whānuitia ana, e rite ana ki ngā momo whakamātautau pakeke matua:

Ngā Poraka Mārō o Rockwell (HRC, HRB, me ētahi atu): Hototahi ki ngā taputapu whakamātautau mārō o Rockwell, e whakamahia ana mō te whakamātautau mārō o ngā rauemi whakarewa.

Poraka Mārō Brinell (HBW): Hototahi ki ngā taputapu whakamātautau mārō Brinell, he pai mō te ine i ngā konganuku he iti te mārō, ngā rauemi rānei he matotoru ngā kōhao.

Poraka Mārō Vickers (HV): Hototahi ki ngā taputapu whakamātautau mārō Vickers, he tino tika, ā, ka taea te ine i ngā wahi mahi angiangi, ngā wāhanga iti, me ngā paparanga mata kua mārō.

Ngā Poraka Mārō o te Takutai (HS): Hototahi ki ngā taputapu whakamātautau mārō o te takutai, e whakamahia ana mō te whakamātautau mārō o ngā wahi mahi nunui, o ngā taputapu pumau rānei.

Poraka Pakari Leeb (HL): Hototahi ki ngā whakamātautau pakeke Leeb, he pai mō ngā whakamātautau kei te papaanga me ngā whakamātautau kore-whakangaro.

2. Whakarōpūtanga mā te Rauemi

Ngā Poraka Pakeke Konganuku: Kei roto ko te maitai waro, te maitai koranu, te maitai kore waikura, te koranu parahi, me ētahi atu, e kapi ana i ngā hiahia whakamātautau o te nuinga o ngā mahi konganuku ahumahi.

Ngā Poraka Mārō Kore-whakarewa: Pērā i ngā poraka mārō kirihou, rapa, me te uku, e hototahi ana ki te ine mārō o ngā rauemi kore-whakarewa.

3. Whakarōpūtanga mā te Tohu Tika

Taumata Paerewa (Taumata 1): Whakamahia hei whakatikatika i ngā whakamātautau pakeke, me te tino tika o ngā tau me te whai i ngā paerewa inenga ā-motu.

Taumata Mahi (Taumata 2): Whakamahia hei whakataurite i ngā whakamātautau o ia rā, hei whakamana hoki i te pumau o ngā taputapu, hei whakatutuki i ngā hiahia o ngā whakamātautau whakaputa o ia rā.

I te hoko poraka pakeke, me taurite te momo whakamātautau pakeke, te whānuitanga pakeke o te mea mahi e whakamatautauria ana, me ngā whakaritenga tika. Me whai te whakatikatika i ngā mātāpono o "ngā paerewa ōrite, ngā āhuatanga ōrite, me te mahi paerewa" hei whakarite i te tika me te whai i ngā uara i inehia.
