Ukuhlonza nokuhlolwa kwemicu

1, ukusetshenziswa kwentambo nezici

Ukusetshenziswa kwentambo kubanzi kakhulu, kusukela ezindizeni, ezimotweni kuya ekuphileni kwethu kwansuku zonke ekusetshenzisweni kwamapayipi amanzi, igesi nokunye kusetshenziselwa inani elikhulu lezikhathi, iningi lentambo idlala indima yokuxhumana eqinile, okwesibili ukudluliswa kwamandla nokunyakaza, kunenhloso ethile ekhethekile yentambo, nakuba izinhlobonhlobo, kodwa inani labo lilinganiselwe.

Ngenxa yesakhiwo sayo esilula, ukusebenza okuthembekile, ukuhlakazeka okulula kanye nokwakhiwa okulula, intambo isiphenduke into ebaluleke kakhulu yesakhiwo kuzo zonke izinhlobo zemikhiqizo yemishini nekagesi.

Ngokusho kokusetshenziswa kwezintambo, zonke izinhlobo zezingxenye ezinezintambo kufanele zibe nemisebenzi emibili elandelayo eyisisekelo: eyodwa ihlanganisa kahle, enye inamandla anele.

2. Ukuhlukaniswa kwentambo

A. ngokuya nezici zabo zesakhiwo kanye nokusetshenziswa, zingahlukaniswa ngezigaba ezine ezibanzi:

Intambo evamile(intambo yokubopha) : umumo wezinyo unonxantathu, usetshenziselwa ukuxhuma noma ukubopha izingxenye.Intambo evamile ihlukaniswe yaba intambo eqinile kanye nentambo enhle ngokusho kwe-pitch, amandla okuxhumana entambo enhle aphezulu.

Intambo yokudlulisa: umumo wezinyo une-trapezoid, unxande, umumo wesaha nonxantathu, njll.

Intambo yokubeka uphawu: yokuxhuma ngokuvala, ikakhulukazi intambo yepayipi, intambo ye-taper kanye nentambo yepayipi ye-taper.

Intambo yenhloso ekhethekile, ebizwa ngokuthi intambo ekhethekile.

B, ngokwesifunda (izwe) lingahlukaniswa libe: intambo yemethrikhi (intambo yemethrikhi) intambo, intambo ye-n, njll. , sisetshenziselwa ukucupha kanye nentambo ebizwa ngokuthi intambo, i-angle yezinyo layo ino-60 °, 55 °, njll. ., ububanzi nephimbo kanye neminye imingcele yentambo ehlobene esetshenziswa usayizi oyintshi (intshi) .Ezweni lakithi, i-angle yezinyo ihlanganiswe ku-60 °, futhi ububanzi nochungechunge lwe-pitch ngamamilimitha (mm) lusetshenziselwa ukubiza lolu hlobo lwentambo: intambo evamile.

3. Uhlobo lwentambo evamile

4.Amagama ayisisekelo emicu

Uchungechunge: endaweni eyisilinda noma eyikholi, i-projection eqhubekayo yakheka ngomugqa ozungezayo onesimo sezinyo esicacisiwe.

Intambo yangaphandle: intambo eyakhiwe endaweni engaphandle yesilinda noma ikhoni.

intambo yangaphakathi: intambo yangaphakathi eyakhiwe endaweni engaphakathi yesilinda noma ikhoni.

Ububanzi: ububanzi besilinda esicatshangelwayo noma i-cone tangent ukuya kumqhele wochungechunge lwangaphandle noma isisekelo sochungechunge lwangaphakathi.

Ububanzi: ububanzi besilinda esicatshangelwayo noma i-cone tangent ukuya esisekelweni sentambo yangaphandle noma umqhele wentambo yangaphakathi.

I-Meridian: ububanzi besilinda esicatshangelwayo noma ikhoni ekhiqiza i-generatrix edlula emiseleni kanye nokuqagela kobubanzi obulinganayo.Lesi silinda esicatshangelwayo noma ikhoni ibizwa ngokuthi isilinda esiphakathi nendawo noma ikhoni.

Uchungechunge olusesandleni sokudla: intambo eshintshwayo ngenkathi izungeza njengokuya kwewashi.

Intambo engakwesokunxele: intambo eshintshwayo uma iphendulwa ngokuphambene newashi.

I-engeli yezinyo: ohlotsheni lwezinyo lwentambo, i-engeli yohlangothi lwamazinyo amabili asondelene.

I-pitch: ibanga le-axial phakathi kwamazinyo amabili ancikene emgqeni ophakathi elihambisana namaphoyinti amabili.

5. Ukumaka intambo

Ukumaka kochungechunge lwemethrikhi:

Ngokuvamile, ukumakwa kwentambo ye-metric okuphelele kufanele kufake izinto ezintathu ezilandelayo:

U-A umele uhlobo lwekhodi yochungechunge lwezimpawu zentambo;

Usayizi wentambo engu-B: ngokuvamile kufanele wenziwe ububanzi kanye nephimbo, ngentambo enezintambo eziningi, kufanele futhi ifake inombolo yokuhola neyomugqa;

Ukunemba kwentambo C: ukunemba kwemicu eminingi ngobubanzi bendawo yokubekezelelana (kuhlanganise nendawo yokubekezelela indawo nosayizi) kanye nobude besinqumo esihlanganisiwe.
