150mm Ine Matapihi Vernier Matapihi ā-roto

Ka pā tika te tika o te whakamahinga o ngā calipers me te mata. Me whai i ēnei whakaritenga i te wā e whakamahia ana:

1. I mua i te whakamahinga, me horoi te caliper me te ine, kātahi ka kumea te anga rūri. Me ngāwari, me pumau te nekehanga i te tinana rūri, kaua hoki e piri, e wetekina, e piri rānei. Whakamaua te anga rūri ki ngā tīwiri whakau, ā, kaua e rerekē te pānui.

2. Tirohia te tūnga kore. Āta pēhia te anga rūri kia tata ai ngā mata ine o ngā maikuku ine e rua. Tirohia te pā o ngā mata ine e rua. Kaua e kitea he turuturu mārama. Ka tohu te tohu waea ki te "0". I taua wā anō, tirohia mēnā kei te hāngai te tinana rūri me te anga rūri ki te rārangi tauine kore.

3. I te wā e ine ana, āta panaia, tōia hoki te anga rūri mā te ringaringa kia paku pā te maikuku ine ki te mata o te wāhanga i inehia, kātahi ka rūrū mārie i te caliper me te ine kia pai ai te pā. Nā te mea kāore he tikanga ine kaha ina whakamahia te caliper me te mita, me mātakitaki mā te ringa o te kaiwhakahaere. Kāore e whakaaetia kia nui rawa te kaha kia kore ai e pā ki te tika o te ine.

4. I te ine i te rahinga whānui, whakatuwheratia te maikuku ine neke o te caliper ki te ine kia taea ai te whakanoho noa i te mea mahi i waenganui i ngā maikuku ine e rua, kātahi ka pēhi i te maikuku ine pumau ki te mata mahi, ka nekehia te anga rūri mā te ringa kia piri pai ai te maikuku ine neke ki te mata o te mea mahi. Kia mahara: (1) kaua e piko ngā mata e rua o te mea mahi me te maikuku ine i te wā e ine ana. (2) I te wā e ine ana, kaua te tawhiti i waenganui i ngā maikuku ine e iti iho i te rahi o te mea mahi kia kaha ai te whakapiri i ngā maikuku ine ki ngā wāhanga.

5. I te ine i te whānui o roto, me wehe ngā maikuku ine i ngā taha tapahi e rua, ā, me iti iho te tawhiti i te whānui i inehia. I muri i te whakatakotoranga o ngā maikuku ine ki roto i te kōhao i inehia, me neke ngā maikuku ine i roto i te anga rūrū kia tata ai ki te mata o roto o te mea mahi, arā, ka taea te pānui i runga i te caliper. Kia mahara: me ine te maikuku ine o te caliper vernier i ngā tūranga whānui o ngā kōhao i ngā pito e rua o te mea mahi, kaua hoki e piko ki raro.

6. He rerekē ngā āhua o te mata ine o te maikuku ine o ngā calipers me ngā ine. I te wā ine, me whiriwhiri tika kia rite ki te āhua o ngā wāhanga inehia. Mena ka inehia te roa me te whānuitanga whānui, me whiriwhiri te maikuku ine o waho hei ine; Mena ka inehia te diameter o roto, me whiriwhiri te maikuku ine o roto hei ine; Mena ka inehia te hohonu, me whiriwhiri te rūri hohonu hei ine.

7. I te wā e pānui ana, me pupuri whakapae ngā calipers me ngā mita kia anga te rārangi tirohanga ki te mata o te rārangi tauine, kātahi ka āta tautuhia te tūranga kua tohua kia rite ki te tikanga pānui hei whakahaere i te pānui, kia kore ai e puta he hapa pānui i te rārangi tirohanga hē.
