Ulwazi lokuchaneka komatshini olufunekayo kumatshini

Ukuchaneka komatshini yinqanaba apho ubukhulu bokwenene, imilo kunye nesikhundla somphezulu wamacandelo omatshini ahambelana neeparitha ezifanelekileyo zejometri ezifunwa yimizobo.Iparameter yejometri efanelekileyo, yobungakanani, ubukhulu obuphakathi;kwijometri yomphezulu, isangqa esipheleleyo, isilinda, indiza, ikhowuni kunye nomgca othe ngqo, njl.;indawo ehambelanayo phakathi kwemigangatho, i-parallel absolute, i-vertical, i-coaxial, i-symmetrical, njl njl.

1. Ingcamango yokuchaneka komatshini
Ukuchaneka komatshini kusetyenziswa ikakhulu ukuvelisa iimveliso, kwaye ukuchaneka komatshini kunye nempazamo yomatshini ngamagama asetyenziselwa ukuvavanya iiparamitha zejometri zomgangatho owenziwe ngomatshini.Ukuchaneka komatshini kulinganiswa nenqanaba lokunyamezela.Ixabiso elincinci lenqanaba liphezulu, ukuchaneka okuphezulu;impazamo yobuchwephesha imelwe lixabiso lamanani, kwaye ixabiso lamanani likhulu, impazamo enkulu.Ukuchaneka okuphezulu komatshini kuthetha iimpazamo ezincinci zomatshini, kwaye ngokuphambeneyo.

Kukho amabakala angama-20 okunyamezelana ukusuka kwi-IT01, i-IT0, i-IT1, i-IT2, i-IT3 ukuya kwi-IT18, apho i-IT01 ibonisa ukuchaneka okuphezulu kwe-machining yecandelo, kwaye i-IT18 ibonisa ukuba ukuchaneka kwe-machining kwenxalenye yeyona nto iphantsi.Ngokubanzi, i-IT7 kunye ne-IT8 zinokuchaneka komatshini ophakathi.inqanaba.

Iiparamitha zangempela ezifunyenwe yiyo nayiphi na indlela yomatshini ayiyi kuchaneka ngokupheleleyo.Ukususela kumsebenzi wecandelo, ngokude nje ukuba impazamo yomatshini ingaphakathi kwibala lokunyamezela elifunwa ngumzobo wenxalenye, kuthathwa ukuba ukuchaneka komatshini kuqinisekisiwe.

Umgangatho womatshini uxhomekeke kumgangatho womatshini wamacandelo kunye nomgangatho wendibano yomatshini.Umgangatho womatshini wamacandelo ubandakanya ukuchaneka komatshini kunye nomgangatho ophezulu wamacandelo.

Ukuchaneka kwe-machining kubhekisela kwiqondo apho iiparameters zejometri zangempela (ubungakanani, imilo kunye nesikhundla) senxalenye emva komatshini zihambelana neeparitha ezifanelekileyo zejometri.Umahluko phakathi kwabo ubizwa ngokuba yimpazamo yomatshini.Ubungakanani bempazamo yomatshini bubonisa inqanaba lokuchaneka komatshini.Okukhona impazamo inkulu, kokukhona isezantsi ukuchaneka komatshini, kwaye impazamo encinci, kokukhona iphezulu ukuchaneka komatshini.

2. Imixholo enxulumene nokuchaneka komatshini
(1) Ukuchaneka komda
Ibhekisa kwiqondo lokuthotyelwa phakathi kobukhulu bokwenyani benxalenye esetyenzisiweyo kunye nombindi wendawo yokunyamezela yobungakanani benxalenye.

(2) Ukuchaneka kobume
Ibhekisa kwiqondo lokuthotyelwa phakathi kwejiyometri yokwenyani yomphezulu wenxalenye yomatshini kunye nejometri efanelekileyo.

4. Izizathu zempembelelo
(1) Impazamo yomgaqo-nkqubo
Impazamo yomgaqo woMatshini ibhekisa kwimpazamo ebangelwe kusetyenziso lweprofayile yeblade eqikelelweyo okanye unxulumano losulelo oluqikelelweyo lokusetyenzwa.Iimpazamo zemigaqo yoMatshini ziyenzeka ikakhulu ekwenziweni kwemisonto, iigiya kunye nemigangatho entsonkothileyo.

Ekuqhubekeni phambili, ukusetyenzwa okuqikelelweyo kusetyenziswa ngokubanzi ukuphucula imveliso kunye noqoqosho phantsi kwesiseko sokuba impazamo yethiyori inokuhlangabezana neemfuno zokuchaneka kokusebenza.

(2) Impazamo yohlengahlengiso
Iphutha lohlengahlengiso lwesixhobo somatshini libhekisa kwimpazamo ebangelwa luhlengahlengiso olungachanekanga.

(3) Impazamo yesixhobo somatshini
Impazamo yesixhobo somatshini ibhekisa kwimpazamo yokwenziwa, impazamo yofakelo kunye nokuguga kwesixhobo somatshini.Ikakhulu ibandakanya impazamo yesikhokelo somgaqo kaloliwe wesixhobo somatshini, impazamo yokujikeleza kwesixhobo sokusonta somatshini, kunye nempazamo yothumelo lwekhonkco lokuhambisa isixhobo somatshini.

5. Indlela yokulinganisa
Ukuchaneka komatshini Ngokwemixholo echanekileyo yokuchaneka komatshini kunye neemfuno zokuchaneka, iindlela ezahlukeneyo zokulinganisa zisetyenziswa.Ngokuqhelekileyo, kukho ezi ndlela zilandelayo:

(1) Ngokubhekiselele ekubeni iparamitha elinganisiweyo ilinganiswa ngokuthe ngqo, inokwahlulwa ibe ngumlinganiselo othe ngqo kunye nomlinganiselo ongathanga ngqo.
Umlinganiselo othe ngqo: ukulinganisa ngokuthe ngqo ipharamitha elinganisiweyo ukufumana ubungakanani obulinganisiweyo.Umzekelo, ukulinganisa ngee-calipers kunye nabathelekisi.

Umlinganiselo ongathanga ngqo: ukulinganisa iiparamitha zejometri ezinxulumene nobukhulu obulinganisiweyo, kwaye ufumane ubungakanani obulinganisiweyo ngokubala.

Ngokucacileyo, umlinganiselo othe ngqo ulula ngakumbi, kwaye umlinganiselo ongathanga ngqo unzima ngakumbi.Ngokuqhelekileyo, xa ubungakanani obulinganisiweyo okanye umlinganiselo othe ngqo awukwazi ukuhlangabezana neemfuno zokuchaneka, umlinganiselo ongathanga ngqo kufuneka usetyenziswe.

(2) Ngokubhekiselele ekubeni ixabiso lokufunda lesixhobo sokulinganisa limele ngokuthe ngqo ixabiso lobungakanani obulinganisiweyo, linokwahlulwa libe ngumlinganiselo opheleleyo kunye nomlinganiselo ohambelanayo.
Umlinganiselo opheleleyo: Ixabiso lokufunda libonisa ngokuthe ngqo ubungakanani bobungakanani obulinganisiweyo, njengokulinganisa nge-vernier caliper.

Umlinganiselo ohambelanayo: Ixabiso lokufunda limele kuphela ukutenxa kubungakanani obulinganisiweyo xa kuthelekiswa nobungakanani obuqhelekileyo.Ukuba umlinganisi usetyenziselwa ukulinganisa ububanzi be-shaft, indawo ye-zero yesixhobo kufuneka ilungiswe kunye nebhloko yokulinganisa kuqala, kwaye emva koko umlinganiselo wenziwa.Ixabiso elilinganisiweyo ngumahluko phakathi kobubanzi be-shaft yecala kunye nobukhulu bebhloko yokulinganisa, okuyimilinganiselo ehambelanayo.Ngokuqhelekileyo, ukuchaneka komlinganiso kuphezulu, kodwa umlinganiselo unzima kakhulu.

(3) Ngokubhekiselele ekubeni umgangatho olinganisiweyo udibana nentloko yokulinganisa yesixhobo sokulinganisa, yahlulwe ibe yimilinganiselo yokudibanisa kunye neyokungadibanisi.
Umlinganiselo woqhagamshelwano: Intloko yokulinganisa idibene nomphezulu oza kuqhagamshelwana nayo, kwaye kukho amandla okulinganisa oomatshini.Njengokulinganisa iindawo ngemicrometer.

Umlinganiselo ongeyena uqhagamshelwano: Intloko yokulinganisa ayidibanisi nomphezulu wecandelo elilinganisiweyo, kwaye umlinganiselo ongeyena woqhagamshelwano unokuphepha impembelelo yomlinganiselo wamandla kwiziphumo zokulinganisa.Njengokusetyenziswa kwendlela yokubonisa, i-interferometry yamaza okukhanya njalo njalo.

(4) Ngokwenani leeparamitha ezilinganiswe ngexesha elinye, lihlulwe libe ngumlinganiselo omnye kunye nomlinganiselo obanzi.
Umlinganiselo omnye: linganisa iparamitha nganye yecandelo elivavanyiweyo ngokwahlukeneyo.

Umlinganiselo obanzi: Linganisa isalathiso esibanzi esibonisa iiparamitha ezifanelekileyo zecandelo.Umzekelo, xa ulinganisa intambo ngesixhobo sokusebenzisa i-microscope, eyona pitch idayamitha yomsonto, impazamo yesiqingatha se-engile yeprofayili yezinyo kunye nempazamo eyongezelekayo yenowuthi inokulinganiswa ngokwahlukeneyo.

Umlinganiselo obanzi ngokuqhelekileyo usebenza kakuhle kwaye unokwethenjelwa ngakumbi ekuqinisekiseni ukutshintshiselana kwamalungu, kwaye isoloko isetyenziselwa ukuhlola iindawo ezigqityiweyo.Umlinganiselo omnye unokugqiba impazamo yeparameter nganye ngokwahlukileyo, kwaye ngokuqhelekileyo isetyenziselwa uhlalutyo lwenkqubo, ukuhlolwa kwenkqubo kunye nomlinganiselo weeparamitha ezichaziweyo.

(5) Ngokwendima yokulinganisa kwinkqubo yokucubungula, ihlukaniswe ibe ngumlinganiselo osebenzayo kunye nokulinganisa okungahambiyo.
Umlinganiselo osebenzayo: I-workpiece ilinganiswa ngexesha lokucubungula, kwaye umphumo usetyenziswa ngokuthe ngqo ukulawula ukucutshungulwa kwenxalenye, ukwenzela ukuthintela ukuveliswa kwenkunkuma ngexesha.

Umlinganiselo wePasitive: Imilinganiselo ethathwe emva kokuba i-workpiece yenziwe ngoomatshini.Olu hlobo lokulinganisa lunokugweba kuphela ukuba i-workpiece ifanelekile okanye ayifanelekanga, kwaye inqunyelwe ekufumaneni kunye nokugatya iimveliso zenkunkuma.

(6) Ngokwemeko yenxalenye elinganisiweyo ngexesha lenkqubo yokulinganisa, yahlulahlulwe ibe ngumlinganiselo we-static kunye nomlinganiselo oguqukayo.
Umlinganiselo ongatshintshiyo: Umlinganiselo umile noko.Njenge micrometer yokulinganisa ububanzi.

Umlinganiselo weDynamic: Ngexesha lokulinganisa, umphezulu oza kulinganiswa kunye nentloko yokulinganisa ishukuma xa kuthelekiswa nemeko yokusebenza efanisiweyo.

Indlela yokulinganisa eguquguqukayo ingabonakalisa imeko yamacandelo asondeleyo kwimeko yokusetyenziswa, eyona ndlela yokuphuhlisa iteknoloji yokulinganisa.
