Chii mutsetse? Pfungwa imwe urefu, muenzaniso yakayerwa

Zvaizoratidza sokuti mutsetse rakadaro? A nyore chishandiso nokuyerwa urefu. Uye chii kuchikoshesa ane muupenyu hwedu! Pasina zvakaoma kuita mudzidzi, injiniya, draftsman.

A Nhoroondo shoma

In dzayo dzose chimiro, sezvo isu Maiona naye, iye ari anozivikanwa kubvira Great French Revolution. Izvi makore anopfuura mazana maviri apfuura. Asi parinowanika unogona yomusi kunyange yapfuura kumwedzi. Munguva kupikidura rekare guta rePompeii, vanochera matongo vakawana akafanana kuwanda hunhu - aibatanidza mapuranga pachaenzaniswa.

Zvino Middle Ages kunopupurira kuvapo ichi chinoshamisa chokushandisa, iyo anoita se bwendefa mutobvu. In yekare Rus simbi nembariro zvinoshandiswa yakayerwa.

Chokwadi, tinogona zvino kutonga kuti kushandiswa akanga kusagadzikana chaizvo, asi kuti ndiye nyaya chidzoke uye kuvandudzika mutsetse.

Pakusarudza mukugadzira zvinhu

Chii mutsetse? A device reproduces achirurama mutsetse mundege nechinangwa spatial chipimo. On wayo zvokunze akacherekedza zviyero, izvo uve millimeter uye sendimita, uye muna Chirungu mutongi - padiki.

Inogona kugadzirwa Kwakashandiswa micheka: mapurasitiki (kupatsanura yakajeka uye opaque, kusanduka uye vanachandagwinyira), paperboard, simbi uye kunyange tishu.

Kuti uone imwe zvakarurama Linear kukura nani kushandisa simbi mutongi. Nekuti mapurasitiki iri neshungu kuchangotanga kuchinja mari uye pasi pokudzora mwando matanda ruchigona kuzvimba. mutongi Plastic njenjemera yamunenge kushandisa, sezvo haritauri kufukidza chifananidzo. Asi zvakawanda huni aizonyatsovachenesa muenzaniso kuti Zvinoda kuramba kucheneswa pakusvibiswa.

Metal mutongi chakagadzirwa jira simbi ine yakabwinyiswa nomumativi ane Chrome kupera iri husingakwanisi ngura.

Kureba mutsetse

Kamwe isu afunga kuti mutsetse uyu yakayerwa, zvinokwanisika kutaura kureba kwayo.

Maererano GOST, panguva yayo pamusoro rinoshandisirwa rinokosha pezvose. Rinogona kubva 150 kusvika 3000 mm. More kudiwa mutsetse, kureba iri 300, 500 uye 1000 mm.

Nechokunze kufanana mutsetse, vane pose makubhiti 18 kusvika 40 mm zvichienderana kureba. Ukobvu yavo nehafu kana mumwe millimeter. All ane equidistant kubva mumwe, kupatsanura Kurohwa kuti kukosha 1 mm.

Zero bhaa ndiyo panotaurwa pfungwa pakuyera zviridzwa. Kazhinji mu mugumo wakasiya mutsetse uye kunoonekwa sechinhu nechiyero chirwere.

On mutongi arşive anogona kuiswa hapana mumwe, asi maviri pachikero. Kune vakadaro kuyera nhumbi iro razero weboka anekodzero uye kuruboshwe.

Saka, kudzidza mutongi - ndiyo nyore chingaita zvokuswedera segwapa aine chikero pariri, kuburikidza paunogona kuvaka geometric zvitarisiko, kuita Linear kuyerwa uye Masvomhu.

Negadziriro zviyero wakashandiswa arşive siyana

Meter ndiye kupfuura chairema yakayerwa, uye basa chinokosha arşive hurongwa zviumbu ndivo sendimita. Mumwe mita ane zana masendimita.

fission Large pasi zvavari vakaronga tsika digits kureva masendimita (cm). Kazhinji, mutemo kureba mutsetse uri masendimita matatu. A guru kure pakati mavanga ndiyo sendimita vakaenzana.

Small dashes rwokuyera hukawanika pakukoka pakati huru deletions, inomiririra millimeters. Mumwe sendimita ane millimeters gumi (mm).

Ngationgororei muenzaniso basa "Kwazvo mutsetse Kureba ballpoint kunyora." How kuzviita?

Mubato inofanira kuiswa iri zvakaoma pamusoro, uye miganhu zvinogona kuitwa chete mutongi.

Zvakakosha kuisa mutsara kuruboshwe kumucheto mubato, unofanira kutevera wayo magumo pamwero pamwe razero chiratidzo. Izvi zvinofanira wakaiswa ruoko rworuboshwe uye kodzero kuchinja nzvimbo kuguma tambo mudziyo.

Extreme nhamba kuswedera kuguma akayera chinhu, uye achava kureba. Toti ndiko 15 masendimita, uye akasara kupesana diki, vachitevera panogumira ekupedzisira anozivikanwa nhamba, idzo ina, zvichareva millimeters. Saka, kubata urefu 18.4 mm.

Kuyerwa chinhu tsanga - nzira iyo rinoitwa nokushandisa chinhu mutsetse. Iyewo, kuyerwa nokuenzanisa kureba kwayo kuyera kukosha. Nokuti kubviswa nezviyero munhu yokusona mbatya, kuita nani kushandisa meter, imwe kwakavharwa nenyama bhendi. Zvakanaka, kana uchida kuyera daro refu, zvinoita yamunenge kushandisa tepi chiyero. Uye pakupedzisira, chii kuwanda arşive? A mudziyo kuyera apo kuverengwa anoverengwa kubva kuruboshwe kuenda kurudyi. The nhamba inowanikwa kurudyi, achasarudza kureba. Zvairatidza zvakanyorwa somunhu grade chakapatsanurwa, semuenzaniso, 0.5 cm.
