“Me tika te take ki roto 0.05 mm” kua oti te tangi, engari ka taea e ia te whakaatu i nga tikanga rereke rereke. Ko te tikanga o tetahi miihini he tika te tuaka mai i te tuhi. Ka taea e tetahi atu te huri i te rakau ki nga pokapu me te panui i tetahi tohu waea ki tetahi hautaka. Ka taea e te tuatoru te neke i tetahi tirotiro i runga i te mata katoa ka kiia ko te mutunga o te rerenga katoa.
Ko enei tikanga kaore i te tino rite te uara. Ko te kaupapa whakatikatika rakau pono me tautuhi i te ahuatanga whakahaere, tau, tūnga ine, te ara rangahau me te ture whakaae i mua i te wa ka riro te hua miihini hei taurangi.

Whakataurite Tere
| Wāhanga | Datum e hiahiatia ana? | Te Aromatawai | He aha te hua ka whakawhirinaki |
|---|---|---|---|
| Te torotika o te raina mata | Karekau he raraunga o waho mo te mana o te puka | Wehenga o ia huānga raina whakahaere mai i tona rohe whakararu tika | Puka mata, te roa o te aromātai me te tātari |
| Te torotika o te raina waenga, tuaka ranei | Karekau he raraunga o waho mo te mana o te puka | I arotakehia te ahuatanga i ahu mai i roto i te rohe whakaahuru kua tohua | Raraunga waahanga, tangohanga āhuatanga me te whakamāramatanga tuhi |
| Te rere porohita | Ae, he tuaka tohu | Hurihia te rereketanga i te wa kotahi hurihanga i te waahanga whiti kua tohua | Tatūnga Datum, porotaka, te rereke me te ahua o te mata o te rohe |
| Te pau katoa | Ae, he tuaka tohu | He rereke i runga i te mata katoa e whakahaeretia ana i te wa e huri haere ana te waahanga me te tirotiro haere | Tatūnga Datum me te whakahiatotanga o te mata/ahua/whakaaronga |
| Papa-hoko "TIR" | Mena ka tautuhia e te tatūnga tetahi | Morahi haunga te iti o te panui tohu i te tatūnga kua tohua | Tautoko, pokapū, teihana tirotiro, hurihanga, paru me te tikanga kaiwhakahaere |
Ko te paerewa tuhi me tana whakaputanga kua tohua hei whakahaere i te whakamaoritanga okawa. Ko nga kupu hokohoko penei i te "TIR" ka whai hua anake ka tuhia te tatūnga tūturu.
ISO 1101:2017 defines the symbol language and interpretation rules for geometrical specifications, including form and run-out. ASME Y14.5 is a separate authoritative GD&T system. A project should name the applicable system and edition; neither an acronym nor a machine display replaces the drawing definition.
He aha te Mana o te Shaft Straightness
Ko te tika he whakaritenga puka. I roto i te GD&T, karekau te mana totika e whakamahi tohutoro paparangi o waho i te anga mana ahua. Kei runga i te waahi me te pehea te tono, ka taea e ia te whakahaere i tetahi huānga raina mata, he raina tauwaenga ranei.
Mo te kaupapa whakatikatika, Ko te "tika" kei te hiahia tonu ki te whakamaramatanga whakahaere:
- Ko tehea ahuatanga e whakahaeretia ana: he raina mata o waho, he tuaka hautaka, he tuaka ahu mai ranei?
- He aha te roa o te aro mātai?
- He maha nga wahanga-whiti e whakamahia ana hei whakaputa i te tuaka?
- Kei te tautokohia te waahanga, kua rawhi, kua ine-kore ranei?
- Ko tehea tātari, ka whakamahia te tikanga whakauru, te taputapu ine ranei?
Ko te mihini e huri ana i te rakau me te panui i tetahi rangahau torotoro i te nuinga o te waa ka kite i te rere i roto i taua tatūnga. Kaua e tapaina aunoatia te hua "tuaka tika" me te kore he rangahau hononga.
He aha nga mana o te rere porohita
Ka aromatawaihia te rerenga porohita e pa ana ki te tuaka datum. I tetahi waahanga whiti kua tohua, ka huri te wahanga 360 nga nekehanga i te wa e maataki ana te tirotiro i te mata whakahaere. Me noho tonu te rereketanga o te panui ki roto i te tepe kua tohua mo taua papa inenga.
Ko te rerenga porohita ka uru atu ki te whakakotahitanga o te porohita rohe, te rereke o te mata me te waahi tuaka e pa ana ki te datum. No reira, karekau te panui teitei e whakaatu kua piko te rakau ki taua teihana. He nick, huri taupa, ara matua, Ko te paru i runga i te tautoko, i te hautaka rereke ranei ka puta he tohu rite.
| Porohita-Runout Whakauru | Pātai Kaupapa |
|---|---|
| Tuaka rā | Pokapū, mau hautaka, he diameter pairati, tetahi atu tohutoro mahi ranei? |
| Mata tirotiro | Te hautaka whenua, tahuri diameter, spline / taputapu mata mahi, tetahi atu waahanga ranei? |
| Teihana tuaka | Kotahi te rererangi kua tohua, he maha nga teihana? |
| Te hurihanga | Katoa te hurihanga 360-tohu me te noho pumau? |
| Ture panui | Peak-to-peak, uara tātari, nga panui tukurua, te algorithm motuhake ranei a nga kaihoko? |
| He rereke te mata | Nga huarahi matua, rua, nga awaawa me nga kino ka whakakorehia, ka arotakehia ranei e te arorau motuhake? |
He aha nga Mana Runout Tapeke
Me whai tuaka raraunga hoki te rerenga katoa, engari ka hipokina e te arotakenga te mata katoa e whakahaeretia ana, kaua ki te waahanga whiti motuhake. Ka huri te wahanga i te wa e hikoi ana te tirotiro i te mata kua tohua, na ka taea e te hua te whakaata i nga rereketanga o te roa, te mata ranei.
Mo te mata porotakaroa, Ko te paunga katoa he uaua ake i te tirotiro noa i tetahi waahi tohu waea. Ko te mahere inenga me whakaatu te haerenga axial, kiato tauira, Ko nga ahuatanga kua whakakorehia me te whai te tirotiro i tetahi ara haere tonu, etahi teihana whaimana ranei.
Kaua e whakapoauautia te GD&Ko te tohu "katoa te rere" me te kianga "te panui tohu katoa." Ka taea e tetahi toa te whakaatu i te TIR morahi me te iti rawa i te teihana kotahi, he tata atu ki te panui omaoma i roto i taua tatūnga, karekau hoki e whakaatu aunoa i te whakatakotoranga katoa-rere ki runga i te mata katoa.
He aha te take e taea ai e te taua rakau te whakaputa hua rereke
Ka huri te uara ine ina huri te tohutoro mahi, tatūnga ranei.
| Huri Tatūnga | Pānga pea |
|---|---|
| Hurihia i runga i nga pokapu, kaua e mau i nga hautaka | Ko te hapa-pokapoka pea ka kaha, ka ngaro ranei |
| Tautoko i runga i nga hautaka rereke e rua | Ko te tuaka tohu me te ahua o te huringa o te kotaha piko |
| Nukuhia te rangahau mai i te hautaka whenua ki te whanui huri | Ko te ahua o te rohe me te rerekee ka huri i te tohu |
| Ine tata ki te ara matua, te whakawhiti maatai, te diameter ranei | Ko te korenga o te tohu ka rite ki te piko |
| Rawhi i te rakau, kaua e ine i te ahua-kore | Ka taea e te kaha whakatika te huna, te hanga rereke ranei |
| Hurihia te roanga tautoko i runga i te rakau kikokore | Ko te paheketanga o te taumaha-whaiaro me te huringa whakautu nohoanga |
| Horoia nga pokapū me nga hoapaki | Ka ngaro pea te rerekee o te paru |
| Whakamahia he CMM hei utu mo te taputapu tohu waea | Tango āhuatanga me te huringa tikanga aro mātai |
Koinei te take he whakaritenga hoko penei i te "TIR whakamutunga 0.03 mm” karekau i oti ki te kore he tohu, teihana, taputapu me te tikanga.
Official shaft-inspection equipment illustrates the fixture issue rather than eliminating it. Marposs lists Vees or centres hei punaha tohutoro waahanga rereke, while Mahr offers center, Tautoko-V me te roera-tautoko i nga waahanga rere. These are different physical verification arrangements. They are not interchangeable unless they realize the intended reference and their results have been correlated.
Gravity Sag, Support Condition and the Verification Setup
A drawing datum or straightness requirement defines the controlled geometry; it does not by itself prescribe the physical supports used to verify the part. For a long, flexible shaft, the support type, axial coordinates, height, end overhang, whakatakotoranga, probe force and rotation method are part of the measurement condition and must be reproducible.
Self-weight deflection is an elastic response to a specific orientation and support arrangement. It is not automatically permanent bend. Adding supports may reduce sag, but it can also overconstrain or artificially hold the shaft straight. Any sag compensation must therefore reproduce an agreed support condition or use a workpiece-specific model validated with representative parts. A universal support ratio should not be applied across solid shafts, hollow shafts, stepped parts and components with uneven mass distribution.
The in-machine setup is useful for process control, but the released-state or customer reference method remains the acceptance method unless a documented gauge-correlation study establishes the agreed relationship. The test plan should freeze the support coordinates, whakatakotoranga, measuring force, evaluation method and part state so that machine, supplier and customer results can be compared.
He pehea te ine a te Tiroiti Aunoa i te Rakau
He maha nga punaha whakatikatika tohu-aunoa e tautoko ana, e kimi ana ranei i te rakau ki runga i nga waahanga kua whakaaetia, hurihia, kohikohi i nga panui radial i tetahi, neke atu ranei nga teihana axial, tātaihia te ahunga piko me te whakamahi i te whakatika tika. Ka inehia ano te rakau ma te whakamahi i taua tatūnga.
Ko te ataata e whakaatu ana i te inenga/hurihuri me te teihana whakatika-pene mo te tono kakano. He taunakitanga mo te raupapa taputapu anake; karekau e whakapumau i te tau katoa, momo pūoko, te manawanui, te hua ranei mo etahi atu rakau.
*Anga Matapuna-ataata.*
Inenga tuatahi
Ka kohia e te kaiwhakahaere nga raraunga koki i ia teihana ine kua whakaaetia. Ka arowhai te kaupapa pakari mo nga nohoanga noho kore, pekepeke kore, kua ngaro te whakapiri me nga papa e kore e tika kia arotakengia he diameter tonu.
Tauira Piko
Ka whakamahia e te rorohiko te tohu ine ki te whakatau i te waahi me te waahi e tika ana kia whakatikahia te ahunga koki. Ko te tauira he rite noa ki nga tohu me nga whakaurunga puoro. Kaore e taea te whakatika i te whakamaoritanga tuhi he.
Te Whakatikatika me te Inenga
Ka whakamahia e te perehi te whakapiko-nui ki tetahi rohe e whakaaetia ana. I muri i te puna, ka huri ano te wahanga, ka rite ano te inenga. He tatau whakatika morahi, te whiu, te rohe kaha ranei ka aukati i te whitiwhitinga kore mana.
Whakaaetanga Whakamutunga
Ka taea e te miihini te whakatau OK/NOK anake ki te ahuatanga kua whakaritea. Mena ka whakaae te kaihoko ki te rakau i runga i tetahi atu taputapu, me whai rangahau ine-whakaritenga i mua i te tikanga o te miihini OK te tikanga o te kaihoko.
Whakawehea te Piko mai i etahi atu Puna o te Nekehanga Tohu
Ko nga whakamatautau rorohiko me te miihini aunoa me wehe te piko tika mai i nga tohu kaore e taea e te whakatikatika te whakaoti.
| Puna Waitohu | Ka taea te pehi i te Whakatika Whakatika? | Whakautu Whakautu |
|---|---|---|
| He piko te rakau rapa/kirihou | Ka taea | Whakamanahia te rohe whakatika me te whakautu whakamuri |
| He rerekee te tuhitaka mai i te miihini | Ehara i te mea | Te arotake i nga raraunga miihini me te hononga ahuatanga |
| Rohe-waho-a-rohe | I te nuinga o te waa ehara i te mea he whakatikatika i te piko | Whakaūhia te porohita me te puna tukanga |
| He paru, he parepare ranei kei runga i nga pokapu/tautoko | Kao | Horoi me te tukurua i te inenga |
| ara matua, marara, riu, poka radial ranei | Ehara i te mata rere tonu | Waiho, whakamahia ranei te inenga mohio-a-ahua |
| He nohoanga noho kore | Kao | Whakatikahia te ariā tautoko/hurihuri |
| Te whakaheke taumaha-whaiaro | Ehara i te mea he piko tonu te panui | Te takotoranga mana, te roanga tautoko, te tikanga utu ranei |
| Hapa taumahinga taputapu/sapa | Ka hiahia pea he inenga rereke me te tukanga | Whakamahia he ine mahi kua whakaaetia, he aratuka-diamita ranei |
Kōwhirihia te Datum mai i te Taumahi me te Tukatuka
I te nuinga o te waa ka whakaatahia e te taurangi tino whaihua te waahi o te rakau ki te mahi ka whai ake, ki te huihuinga whakamutunga ranei. Hei tauira, Ka taea e nga hautaka kawe te tautuhi i te hurihanga mahi o te rakau motuka. Ka tika pea nga pokapū i te wa e huri ana. Ka hiahia pea te rakau pouaka hiko ki te ine inenga mahi me te inenga.
For stepped or multi-diameter parts, the functional datum hierarchy must be documented before the measuring stations are programmed. Ko te Otinga Whakatika Motika Noke Noke Iti shows why profiles, bearing lands and section transitions need separate measurement and protection decisions.
*Source-video frame.* The solution should record separate zones for support, hurihanga, ine me te pehi. Ka īnaki noa enei rohe ina whakaae ana te ahua o te mata me te mahi morearea.
Tauritenga ine: Hua Miihini vs Hua Kiritaki
Ehara i te mea okawa te hononga ine. E rua nga punaha ka taea te tukurua me te kore e whakaae na te mea ka whakatauhia e ratau nga toki tohu rereke, ka arotakehia ranei nga papa rereke.
The comparison must also confirm that both methods address the same measurand. NIST notes that what an instrument actually senses can differ from the intended measurand because the measurement model, probe interaction, data analysis and error sources differ. NIST also describes every measurement result as an estimate whose uncertainty gives a reasonable bound, so a borderline value needs an agreed conformity decision rule rather than blind reliance on display resolution.

FAQ
He rite tonu te TIR ki te rerenga katoa?
Ehara i te aunoa. Ko te tikanga o te TIR ko te rereketanga i waenga i te panui tohu morahi me te iti rawa i roto i tetahi tatūnga. Ko te rerenga katoa he GD kua tautuhia&Ko te ahuatanga T i arotakehia e pa ana ki tetahi tohu i runga i te mata kua oti te whakahaere. Tuhia te tikanga tuturu, kaua ki te whakawhirinaki ki te acronym.
Ka taea e au te huri tika i te uara rere ki te tika o te rakau?
Kaore he hurihanga o te ao e whai mana. Ko te rere ka taea te piko, porotaka, hikaka, hapa rā, nga ahuatanga o te mata me nga paanga taapiri. Ko te whakahoatanga e hiahia ana ki te waahanga hangahanga me nga tatūnga inenga.
He aha te mea ka huri te uara ina huri au i te rakau ki runga i nga hautaka rereke?
