Chero nyanzvi yekufananidzira inoda kuzadzikisa chimwe chezvinangwa zvakakosha - kugadzira zvipikiri zvakakwana zvekugadzira. Maonero ekuzviona kwemafomu acho anowanzova chirevo chevatenzi vemazuva amangwana avo vanodzidziswa opilivat chinyorwa chekuita. Asi izvi hazvisi maererano netsika yekuumba maitiro ekugadzira maitiro, asi pane ruzivo rwezvakakosha zve geometry, anatomy, uye aesthetics.
Munhu anofungidzirwa anosangana zuva roga roga nemhando dzakasiyana-siyana dzevheiri dzepachipi uye basa rake ndokupa minwe gumi imwe yakasiyana uye chimiro chimwechete chembambo yekugadzirira. Pasina mamwe mazano, hazvigoni kuita izvi nenzira yakarurama. Aya matanho anodiwa kuti azadzise mutsara wemasonji, uyewo kuongorora kururamisa kwechimiro. Mudzidzisi wechidiki anofanira kunge ane chinyorwa chakanyatsoratidzwa, umo maanenge achifamba nematanho ekugadzira zvakanaka misumari.
Pane zvikamu gumi nezviviri zvinonyanya kukoshesa kwekugadzirwa kwembambo yekugadzirira.
Mutsara wokutanga unotorwa mumuganhu wekutenderera mukati mepalanx yemunwe. Iyi mutsara ndiyo inongororwa yeimwe mitsetse.
Mutsara weChipiri - uyu mutsara unofananidzwa nemutsetse wekutanga uye unogadzirisa urefu hwemucheto usina mahwanda wepikiri. Iko kunongedza kwechipiri mutsara kunoongororwa sezvinotevera: shingairira pamuromo wechipfuva chakasununguka chembambo kubva mukati.
Mutsara wechitatu uye wechina unopindirana kune wechipiri mutsara. Mitsara iyi inotangira apo mhedziso yeusinairi inosimuka kubva kumazvitema kana kuti nzvimbo dzinonetsa dzinoguma (pakatarisana nechepakati nechechipiri). Iko inofungidzirwa kuti yakagadzirirwa inopiwa kumucheto wakasununguka wechipikiri (kuenzanirana kwechetatu neyechina mitsetse nechokuremekedza kumutsara wekutanga kunonzwisisika pamwe chete nekufungidzirwa kwechipiri mutsara).
Mutsara wechishanu unofananidzwa neikateline line. Mutsetse unotanga uye unoguma kune rumwe rutivi rworuboshwe uye rworudyi rwemamiriro ekudzvinyirira. Iyo yechitatu yepamusoro yemubhedha wechipupuriro inoiswa. Pachine chikamu chekusimudza kwepfungwa yekusimudza uye cuticle line, kupfeka kwekugadzira kunoitwa pasina. Iyo yakapfekedzwa inoshandiswa pamakiromita 2 mm kubva pamiganhu yekateti, uye kubva kumativi ekudzvinyirira nzvimbo pa 1 mm kure. Iyo yechitatu yepamusoro yemubhedha wechipupuriro inoiswa.
Mitsara yechitanhatu neyechinomwe inofananidzwa nemutsara wokutanga, kuburikidza nechitanhatu chechipiri mutsara (kuruboshwe uye kurudyi rwekutanga). Mitsara yematanhatu nemana 7 ichayananiswa, inonyatsova yakasviba kumitsara 3 ne4. Ukuru hwemashoko ari pamiganhu iyi inofanira kuva zvishoma pasi pe 1 m.
Nhamba yechisere ndiyo nheyo yakakwirira yepamusoro, sezvo uwandu hwezvinhu zvakashandiswa ndi 1-2 mm. Pano uhu hunoenderana nehuwandu hwepayipi yepiyeri mumutungamiri wekureba, pamwe nehurefu hwemucheto wakasununguka wechipikiri. Kana iyi yakareba mumutungamiri wenguva refu isingapfuuri 50% yehurefu hwembambo yembambo, ipapo chikamu chechisere chichava pamutsara wekutanga pakati peketari yepikiri. Kana urefu hwacho hwakaenzana nehurefu hwebhedha rembambo mumutsetse wenguva refu, ipapo huchisere huchava pakati pechetatu chetatu chembambo. Asi kana urefu hwacho huchipfuura hurefu hwembambo dzembambo mumugwagwa wakareba, ipapo munyaya iyi yechisere ndeye nzvimbo yechisere iyo iri pamutsetse wekutanga uye inosara chetatu chechepasi chevheiri rembambo, pamwe nechetatu chepamusoro pamucheto wakasununguka wechipikiri. Muchiitiko ichi, sawdust inotakurwa pakati pemutsara wechitanhatu nechinomwe uye inobviswa kubva pamusere wechisere kusvika kumutsara wechishanu.
Mutsara wepfumbamwe uri pakati pemutsara wechitanhatu uye wechinomwe unoenderana nemutsara wokutanga. Uyu mutsetse unotanga munharaunda ye8, uye unoguma pachitenderera nemutsara wechipiri. Kubva kunharaunda 8 nzvimbo 9, nzvimbo yacho yakasvikwa, yakanyatsoyerera kusvika kumiganhu 2, apo kuwanda kwemashoko kunofanirwa kunge kusingapfuuri 1 mm (ita mushushi).
Chigumi chegumi chinenge chichiitwa pakati pe 3rd uye 4th line kubva kumativi emucheto usina mahwanda wepikiri. Mitsara 3 ne4 inopindirana nemutsetse wegumi, uye nharo dzekupindirana dzinofanira kunge dziri pazinga rimwe chete.
Yechigumi nerimwe inotarisa chimiro chemutsara wechipiri (kana misumari ichionekwa kubva kune rumwe rutivi rwekwereti). Mutsara 11 unofanirwa kutarisa kuenzanisa kwezvikamu zvakasiyana zvepamusoro.
Ita gumi nembiri mutsara inozadza kuumbwa kwemhepo yakasununguka yechipikiri.
