Izwi rokuti kerf rinoshandiswa kurondedzera kubwinya kwehutema huni hwekuveza huni inoita mundiro wehuni sezvainocheka kuburikidza nayo. Izwi iri dzimwe nguva rinoshandiswa kurondedzera kuwanda kwemajero pachayo; somuenzaniso, iwe unogona kuona kuiswa kwetenderedzwa yakaona tsanga kana tafura yakatarisa mavara akaisa mutsara waro. Semuenzaniso, mumwe mugadziri anopa mutambo we cross crosscut wakaona tsanga ine kerf ye 0,098 inches (2.5mm), asi muiti mumwechete anopa tsanga yakanaka-yakagadzika nehupamhi hwakafara hwe 0.087 inches.
Kukosha kweKarefu Yakakura
Woodworkers vanocherechedza hupamhi hwekeri kuitira kuti varambe vakanyatsogadzirisa pavanenge vachicheka zvikamu zvezvipfeko zvakaisvonaka zvehuni. Pamapurogiramu epakanyatsokonzera kuvhiringidzika kwakakosha, iyo inenge 0,098 inch yeera yakareba inogona kukosha kana kuenzanisa nekucheka zvikamu. Kusvikira zvishoma, vashandi vanogadzirisa uye vane hanya nebasa rakasvibiswa rinokonzerwa nemashizha ane mavara akaoma. Nokufamba kwemazuva, huwandu hunodhura hwehuni hwehuni hunoshandiswa kuva yakasvibiswa sawdust nemazambu akaona, uye iyo inotapisa iyo blade, iyo shoma shoma ichavapo.
Zvinokonzera Kugadzirisa Upamhi hweKerf
Iyo yakareba yakawanda inowanzonyatsotsanangurwa kuti iite tsvina, yakadai seyo inoshandiswa pamatafura, mabhesi, uye machesi. Kunyange zvazvo mabhanji ebhanji, somuenzaniso, anewo kerf bopha, izvi hazvisi zvido zvishoma kune vaiti vemiti nokuti mabhanji emashamba eine mashomanana kutanga uye haaparadzi miti yakawanda.
Iyo yekeri inotsanangurirwa nehupamhi bwemaoko pachayo, ne "misoro" yemeno (iyo yakatarisa kubva pameso ayo mazino akabatanidzwa kune blade), uye nekudengenyeka kwekasi.
Mazai akavakwa kakawanda anowanzove ane mazino akaremara eti carbide akasungirirwa pamusoro pechina risina tsvina ine chirevo chinogadziriswa chinogamuchirwa kuti chikurumidze asi chigunwe. Izvi zvinowanzoshandiswa pakugadzira basa rokuveza. Aya mahwendefa achava nechepamusoro.
Nokuda kwehuni hwakanaka, zvinowanzoshandiswa kushandisa mashizha matsvuku nemeno akawanda ane zvishoma kana asingatauri angled.
Kakawanda mazino haawedzerwi pajasi asi akabatanidzwa zvakagadzirwa musimbi yesimbi pachayo. Izvi zvinokonzera kushandiswa kwakanyanya uye imwe inoshandiswa kubva mune zviduku kubva pahuni duku huputswa kuburikidza nemakona makuru. Izvi zvinogona kuva chinhu chakakosha kana uchishanda nemiti inodhura yakawanda yehuni.
Chimwe chivara chekuona chisina kubatana chichanyunyutika apo ichicheka, uye izvi zvinogona kuwedzera upamhi hwechifigiro nemwero unokosha. Nekugadzirisa kwekucheka uye kushandiswa kwekushandisa kwehuni, nguva dzose ita nechokwadi kuti mazai ako akabatanidzwa zvakakodzera.
