Uyintoni na umqondiso ubukhulu nendlela yokufumana phezu yezitshixo?

Ekuqaleni kwisiqingatha sesibini senkulungwane XVIII eNgilani, i-revolution industrial kwinkulungwane XIX, kulo lonke kumazwe amaninzi eYurophu ehlabathini. It waphawulwa luphuhliso olukhawulezayo zobugcisa kunye nemveliso mveliso. Manufacturing kwimveliso basuka kwiifektri kunye zocweyo mveliso emikhulu. Noko ke, akulula xa uqeqeshelwa ngemveliso inyanda owodwa kwaye ezincinane ubunzima, kwakunye kwisahlulo yabasebenzi wawufuna nokudalwa ezahlukeneyo uyilo kunye namaxwebhu zeteknoloji, nto leyo eyakhokelela ekubeni kuphuhliso lwamacandelo efakiwe - ukuzoba.

Kokufika emgangathweni

Draw ikuvumela wenze lumelo olubonakalayo lwe le into efunekayo ukuze imveliso yawo. Nangona kunjalo, ngenxa yokuba kuveliswe le imbonakalo lemveliso akwanelanga. Lo mzobo ikwaqulathe ubungakanani, isikali, iimfuno zobugcisa, izinto kunye nezinye iimpawu izinto. Uphuhliso olulolunye kwimveliso kuye kwakhokelela nokwahlulwa yabasebenzi, xa amacandelo enziwa kwizityalo ezahlukeneyo, kwaye ke uhlanganisa imveliso ogqityiweyo. Oku kwakudinga ezamasiko kunye nokumiselwa komgangatho nxalenye nemizobo imithetho single kubulawa. Kuba lula neesimboli ulwazi Umbono lobuchule ziye zaziswa, ezifana, ngokomzekelo, umqondiso ubukhulu okanye ubukhulu, ukuququzelela ukungena ubonisa iimpawu.

Iisimboli: ubukhulu uphawu

Nemigangatho Ukubonelela imiqondiso ezahlukahlukeneyo, nto leyo ebangela ukuba abhale parameters zeijiyometri zobugcisa kubonisiwe nempahla: Iimpawu radius, ubukhulu, angle unyamezelwano kunye nesibonelelo machining. Le nkxalabo efanayo kunye sangqa leyo emiselwe ubungakanani le mingxuma izidumbu revolution. Le Isingqi ohlanganisa iingongoma ezimbini kwisangqa (sphere) watyhutyha ilizwe iziko layo (zakhe), kwaye ngokuba ubukhulu. Njengoko kubonisiwe kumanani? UMarko imele netoti isangqa, awela-umgca ityekele ^kwi-45 ° ukuya nkqo bejonge ngku. Kwezinye iimeko, isiLatini ileta D, nto leyo kuvumeleke ukusetyenziswa belingana kunye umlinganiswa ophambili.

uphawu ubukhulu eLizwini

Ngophuhliso zobugcisa computer amaninzi amaxwebhu yoyilo waqala ukutshintshela kwi-elektroniki, nto leyo ekwenza kube lula ukudalwa, ukugcinwa, ukudlulisa nokuprintwa imizobo kunye vane. Ukuza kuthi ga ngoku, iinkqubo ezizodwa ezisetyenziswayo. Umzekelo, ukuba umzobo AutoCAD iyasetyenziswa, yaye amaxwebhu yombhalo - iLizwi, ziyingxenye yempahla ye-Microsoft Office. Ukongeza software kuhlawulwa, kukho wasimahla: NanoCAD, Vula Office.

Ngenxa yoko, safudukela kunye neendibano, kuquka ubukhulu kophawu kwezi nkqubo. On umgangatho lwebhodi yezitshixo oko ayisekho, ke ngoko, ukuba ukuyifakela uxwebhu wadala ngokusebenzisa umhleli wokubhaliweyo iLizwi, kufuneka kudlule le ndlela ilandelayo: "Faka → Symbol → Ezinye abalinganiswa → uyicima" Font "kwi« Uphawu »→ nghi». ububanzi uphawu ikhowudi kwi "nomlinganiswa (hex)" - 00S6. Ekubeni le ngxenye engekho kuzo zonke lwamagama, oku kutshintshwa nge Ibhini "on": - ". Unicode (16)" "O", ikhowudi 00D8 kwi
