Isahani yawe yo hejuru iri ku ruhande.
Oya, ntabwo yahisemo kukwibeshyaho. Ariko niba ari icyuma gishongeshejwe kandi ukaba umaze igihe kinini ukoresha icyuma gikonjesha ahantu hose, hari amahirwe menshi ko igipimo urimo kubona kitari icyo utekereza.
Dore uko bigenda koko: icyuma gifata ubushuhe, kigakorana n'ibikoresho bikonjesha bishingiye ku mazi, kandi kigatangira kugwa ingese kuva uhagaritse kugisiga amavuta. Ndetse no mu maduka yumye cyane, ubushyuhe buhinduka butuma gikomeza kwaguka no gushonga buri gihe. Shyira igice cy'ubuziranenge kuri iyo saha saa mbiri za mu gitondo iyo iduka rikonje, hanyuma urebe igice kimwe saa munani z'amanywa nyuma y'uko imashini zimaze amasaha menshi zikora - imibare ishobora kudahura. Kandi niba wibaza impamvu CMM yawe ikomeza gutsindwa mu bushakashatsi bw'ubushobozi nubwo ibintu bisa nkaho bisa, ahantu hawe hashobora kuba ari ho nyirabayazana w'ibibazo.
Ibikoresho byo gupima granite ntabwo bifite iki kibazo.
Si ukubera ko ari ibintu bitangaje. Ariko igipimo cy’ubushyuhe cya granite kiri hagati ya 4.5 × 10⁻⁶/°C—hafi kimwe cya gatatu cy’icyuma gishongeshejwe. Mu burebure bwa mm 600, uruziga rwa 5°C rutanga impinduka zingana na mm 0.001 kuri granite ugereranyije na mm 0.012 cyangwa zirenga kuri icyuma gishongeshejwe. Mu gutunganya neza aho uharanira ubushobozi bwa mm 0.005, itandukaniro riri hagati yo gusimbuka no gusimbuka.
Hari iduka numvise bavuga ko ryahinduye ubuso bwaryo bw’ibanze bwo kugenzura kuva ku cyuma gikozwe mu cyuma gikozwe mu cyuma gikozwe mu cyuma gikozwe mu cyuma gikozwe mu cyuma, maze nsanga igipimo cy’ibisigazwa byaryo cyaragabanutse—atari ukubera ko imashini zabo zarushijeho kuba nziza, ahubwo ni ukubera ko uburyo bwo gupima bwazo bwavuze ukuri.
Ikintu gishimishije kuri granite, kandi ibi ntibivugwaho cyane, ni uburyo ikemura ibyangiritse.
Ujugunye agakoresho ko gupima ku isahani y'icyuma? Ushobora kubona agace kazamutse. Urwo rusobe ruto rwerekana ko ruhagaze neza, none buri gice cyose ugenzura kuri ako gace kiba gipima nabi. Nta kimenyetso na kimwe kigaragara—ni ukwiyongera bucece kw'ikosa.
Urakubita igipimo kimwe ukoresheje granite? Uzabona ifu. Wenda umwobo muto. Ariko dore ikintu - igice gisigaye cy'ubuso kiracyari gityaye. Ushobora gukoresha agace katangiritse ufite icyizere cyuzuye. Ikosa riri ahantu runaka kandi rigaragara, ntirihishe kandi rirakwirakwira.
Ibi ni ingenzi kurusha uko abantu babitekereza mu mikorere aho ibyuma bikoreshwa mu gutunganya ibyuma bikoreshwa nabi umunsi ku wundi.
Guhindagurika kw'ubushyuhe ni cyo kintu cyica mu buryo bunonosoye.
Tekereza ibi: uri gukora akazi ku wa mbere mu gitondo. Ubushyuhe bw'iduka ni 18°C. Umuntu wawe urimo kugenzura ingano zose z'ingenzi, ibintu byose bisa neza, ibice birimo gukora. Hanyuma ku wa gatanu nyuma ya saa sita biragera, maze mu buryo butunguranye umuhanga mu by'ikoranabuhanga atangira gupima ibice byari bimeze neza icyumweru cyose. Ni iki cyahindutse? Imashini ntizahindutse. Abazikoresha ntibahindutse. Ariko ubushyuhe bw'ikirere bwarahindutse—wenda kuri dogere 4 cyangwa 5 mu gihe sisitemu ya HVAC ihanganye n'imimerere yo mu mpera z'icyumweru, cyangwa mu gihe izuba rihinduka kandi rishyushye uruhande rumwe rw'inyubako.
Amasahani y'icyuma azakura kandi akorohe bitewe n'izi ngendo. Granite ntabwo izakomera.
Niyo mpamvu laboratwari zo mu rwego rwo hejuru zikoresha granite gusa mu myaka ibarirwa muri za mirongo. Si umuco—ni uko granite iguha icyerekezo kidahindagurika bitewe n’ibidukikije.
Ikindi kintu kimwe kirengagijwe: kudatuma ibintu bihindagurika.
Ibikoresho bigezweho byo gukora imashini birahindagurika. Ingufu zikoresha umuvuduko wa 15.000 RPM, zinyura vuba, ibikoresho bya hydraulic—byose bitanga ingufu za mekanike zinyura mu gitereko cy’imashini, zinyura hasi, zijya mu gipimo cyawe. Ku buso bw’icyuma gikozwe mu cyuma, ibyo bihinda bikomeza. Urushinge rwawe rwerekana ko imashini ikora irahinda. Ishusho zawe za digitale zirahindagurika. Ugerageza gusoma 0.001mm iyo imiterere yawe yose irimo kunyeganyega.
Granite ifata izo ngufu. Ingano yayo isanzwe yo kugabanya ubushyuhe iruta icyuma gishongeshejwe inshuro zigera ku icumi. Ni nko gushyira uburyo bwo gupima ku cyuma gifata ubushyuhe. Imibare irakomera vuba, isomwa rirashobora gusubirwamo, kandi ushobora kwizera ibyo ubona.
Niba wibaza ku bijyanye n'ikoreshwa ry'ibikoresho nyabyo, dore ibyo ushobora kuba urimo guhangana nabyo:
Amasahani yo kugenzura no gushushanya—kureba ubugari, uburinganire, n'ubugari. Amaduka menshi akeneye nibura isahani imwe nziza yo gushingiraho aho aherereye.
Karaba nziza zo kugenzura neza imiterere y'umurongo wa CNC yawe. Niba imashini yawe idakora neza, buri gice ukora kiba gifite iryo kosa. Gukora igenzura rya gatatu buri cyumweru bifata iminota itanu kandi bigafata ibibazo mbere y'uko biba ibibazo by'igice.
V-blocks zo gufata ibice by'umuzenguruko mu gihe cyo kugenzura. Ibikoresho by'umuzenguruko biragoye kubipima buri gihe—V-blocks zirakemura icyo kibazo.
Impande zigororotse zo kugenzura inzira z'imashini n'ubuso bunini aho udashobora gushyira isahani.
Uburyo bwo kuzamura ibikoresho by'akazi kugira ngo ubashe kubona ibintu byari guhishwa.
Kumenya neza amanota: ibikorwa byinshi byo gukora neza bisaba amanota ya 00. Ibyo biguha ubushobozi bwo kwihanganira ibintu bingana na mikorometero 1.5 kuri metero imwe. Icyiciro cya 0 ni gito cyane kuri mikorometero 4—ni byiza iyo ugenzuye neza ariko ntabwo ari iyo ukoze cyane. Icyiciro cya 000 ni cyo gikoreshwa muri laboratwari, mikorometero 0.5 cyangwa irenga, kandi mu by'ukuri ni byinshi cyane keretse niba uri mu kazi ko gupima ikirere cyangwa mu by'ikoranabuhanga.
Itegeko nkoresha: ibikoresho byawe bigomba kuba bifite ireme rimwe cyangwa abiri neza kurusha ubushobozi bwo kwihanganira ibintu ugerageza gufata. Niba ubushobozi bwawe bwo kwihanganira ibintu bukabije ari ± 0.02mm, plaque ya Grade 0 (kwihanganira ibintu hafi 0.004mm/m) iguha amahirwe yo kumererwa neza.
Kubungabunga biroroshye kandi mu by'ukuri, granite irababarira.
Bikomeze bisukuye. Bihanagure nyuma yo kubikoresha, cyane cyane niba wakoresheje ubwoko ubwo aribwo bwose bw'amazi yo gukata. Koresha granite cyangwa isukura plate ikwiye, ntabwo ari imiti isanzwe ikoreshwa mu iduka. Shyigikira neza plate nini ku bitereko byabigenewe - inkunga idakwiye ituma impande zawe zihinduka kandi ikangiza imiterere y'aho ziherereye.
Bisubiremo buri gihe. Kongera kwemeza buri mwaka ku bikoresho bikoreshwa cyane, buri myaka ibiri ku bikoresho bikoreshwa mu buryo buke. Ntabwo bihenze, kandi biguha icyemezo cy'uko inyandiko zawe zikiri nziza.
Dore aho wahera niba ushaka guhindura:
Shaka ubuso bwawe bw'ingenzi cyane—ubwo ukoresha mu gusuzuma bwa nyuma ibice byawe bikomeye cyane. Aho niho granite ihindura itandukaniro rikomeye.
Noneho reba uko igenzura ryawe rikorwa. Ni hehe utakaza umwanya urwanya ibipimo bidahuye? Ni hehe ukeka ko hari ikosa ryo gupima ariko ntubigaragaze? Abo ni bo bazakoresha ibikoresho bya granite bya kabiri n'ibya gatatu.
Ntabwo ari ngombwa gusimbuza ibintu byose icyarimwe. Ariko gusimbuza icyuma kimwe cyangwa bibiri bizakwereka vuba niba granite ikwiye gushorwa mu bikorwa byawe byihariye.
Amaduka menshi ahinduranya ibicuruzwa ntabwo asubira inyuma.
