Iindaba-Umatshini we-CMM GMM kunye nesikhokelo sokulinganisa

Yintoni umatshini we-CMM?

Khawufan 'ucinge ngomatshini we-CNC-ye-CNC-isitayile esinokulinganiswa kakhulu ngendlela ezenzekelayo. Yiloo nto i-CMM yoomatshini!

I-CMM imele "umatshini wokulinganisa olungelelaniso". Mhlawumbi ziseza zixhobo zokulinganisa ezi-3 zokulinganisa ngokwendibaniselwano yazo yokuguquguquka, ngokuchanekileyo, kunye nesantya.

Izicelo zoomatshini bokulungelelanisa

Oomatshini bokulinganisa baxabiseke nangaliphi na ixesha imilinganiselo echanekileyo efanelekileyo kufuneka yenziwe. Kwaye eyona nto inzima kakhulu okanye uninzi lwamanyathelo, kokukhona kuya kuba negalelo ngakumbi ukusebenzisa i-CMM.

Ngokwesiqhelo i-CMM isetyenziselwa ukuhlolwa kunye nolawulo oluphambili. Oko kukuthi, basetyenziselwa ukuqinisekisa ukuba icandelo lihlangabezana neemfuno zomyili kunye neenkcazo.

BanokusetyenziswaInjineli ye-Reverseriinxalenye ezikhoyo ngokwenza imilinganiselo echanekileyo yeempawu zabo.

Ngubani owenzi oomatshini be-CMM?

Umatshini wokuqala we-CMM waphuhliswa yiNkampani yeFeranti ye-Scotland ngeminyaka yee-1950. Bayimfuneko ukuze balinganiswe ngokuchanekileyo amacandelo kwi-aerospace kunye namashishini okukhusela. Oomatshini bokuqala banee-axes ezi-2 zentshukumo. 3 Maomatshini boomatshini abaziswanga ngeminyaka yoo-1960 yi-DEA ye-Itali. Ulawulo lwekhompyuter lwahamba ekuqaleni kweminyaka yee-1970, kwaye waziswa yiSheffield ye-USA.

Iindidi zoomatshini we-CMM

Zintlanu iintlobo zomatshini wokulinganisa:

Uhlobo lwebhulorho le-CMM: koluyilo, eyona ixhaphakileyo, intloko ye-CMM ikhwela kwibhulorho. Elinye icala lebhulorho likhwela kuloliwe ebhedini, kwaye enye ixhaswa kwi-sushion yomoya okanye kwenye indlela ebhedini ngaphandle kwesikhokelo.
I-cantlever cmm: I-cantilever ixhasa ibhulorho kwelinye icala.
I-GNGRY CM: I-gentry isebenzisa isikhokelo kulowo womibini amacala, njenge-cnc router. Ezi ziqhelekile ezinkulu ze-cmm, ke zifuna inkxaso eyongezelelweyo.
Ingalo ethe tye ye-CMM: umfanekiso ongumntu ocingayo, kodwa ngebhulorho yonke uye phezulu uye ezantsi kwingalo enye kunokuba yeyakho i-axis yakho. Ezi zezona zincinci ze-cmm, kodwa zinokulinganisa ubunzima obukhulu zangamacandelo anjengemibutho yemoto.
Uhlobo lwengalo ephathekayo cmm: Aba matshini basebenzisa iingalo kwaye babeka ngesandla. Endaweni yokulinganisa i-XYZ ngokuthe ngqo, bafaka i-Couthorionates ukusuka kwindawo ejikelezayo ye-hlangani nganye kunye nobude obukhoyo phakathi kwamalungu.

Ngamnye uneengenelo kwaye engalunganga kuxhomekeka kwiindidi zemilinganiselo ekufuneka yenziwe. Ezi ntlobo zibhekisa kwisakhiwo somatshini esisetyenziselwa ukubeka indawoprobeisalamane kwinxalenye elinganiswe.

Nantsi itafile enesiphatho ukunceda ukuqonda i-prosfres kunye ne-CLI:

Uhlobo lwe-cmm	Ukuchaneka	Bhetyebhetye	Eyona isetyenziselwa ukulinganisa
Ibhulorho	Phezulu	Phakathi	Izinto eziphakathi ezilinganiselweyo ezifuna ukuchaneka okuphezulu
Cantilever	Iphezulu	Iphantsi	Izinto ezincinci ezifuna ukuchaneka kakhulu
Ingalo ethe tye	Iphantsi	Phezulu	Izinto ezinkulu ezifuna ukuchaneka okuncinci

Ingalo yengalo ephathekayo	Isezantsi	Iphezulu	Xa uqhotyoshelwe ngokupheleleyo kwiikhrayitheriya ezinkulu.

I-propes idla ngokubekwa kwi-3 yemilinganiselo ye-X, Y, kunye no-Z. Nangona kunjalo, ngakumbi oomatshini abanobunkunkqele banakho ukuvumela kwakhona i-angle ye-puty itshintshiwe ukuba itshintshe imvume engakwazi ukufikelela kuyo. Iitafile zoojikelezo zinokusetyenziselwa ukuphucula ubuchule bezinto ezahlukeneyo.

Ii-CMM zihlala zenziwa ngeGranite kunye ne-aluminium, kwaye zisebenzisa iibheri zomoya

Iprobe yesosinsane esimiselweyo apho umphezulu wenxalenye yenziwe khona xa kwenziwa umlinganiselo.

Iindidi zeProbe zibandakanya:

Umatshini
I-optical
I-laser
Isibane esimhlophe

Uomatshini bokulinganisa basetyenziswa ngeendlela ezintathu jikelele:

Amasebe olawulo esemgangathweni: Nantsi indawo egcinwe kwigumbi elicocekileyo lemozulu elawulwa yi-wandisa ukwandisa ukuchaneka kwabo.
Phakamisa ivenkile: Apha i-CMM iphantsi koomatshini be-CNC ukwenza ukuba kube lula ukwenza uvavanyo njengenxalenye yemveliso yokwenza ubuncinci phakathi kwe-CMM kunye nomatshini apho amalungu anematshini. Oku kuvumela imilinganiselo ukuba yenziwe ngaphambili kwaye inokubakho kangako okhokelela kulondolozo njengoko iimpazamo zichongiwe kungekudala.
Iphathwayo: I-CMM ephathekayo ilula ukujikeleza. Banokusetyenziswa kumgangatho wevenkile okanye nokubamba indawo kude kwiziko lemveliso ukulinganisa iinxalenye zentsimi.

Ngaba zichanekile kangakanani oomatshini be-CMM (cmmm)?

Ukuchaneka koomatshini bokulungelelaniswa kuyahluka. Ngokubanzi, bajolise kwi-micrometer echanekileyo okanye ngcono. Kodwa akulula. Enye into, kukho impazamo ubungakanani, ke imposiso yokulinganisa i-CMM inokuchazwa njengefomumu emfutshane ebandakanya ubude bomlinganiso njengento eyahlukileyo.

Umzekelo, i-cmm ye-Classic ye-Hexagon yeHlabathi idweliswe njenge-CMM efikelelekayo i-CMM, kwaye ikhankanya ukuchaneka kwayo njengoko:

1.0 + L / 300Um

Ezo migangatho zikwimicrons kwaye ichaziwe kwimm. Masithi sizama ukulinganisa ubude benqaku le-10mm. Ifomula inokuba yi-1.0 + 10/300 = 1.0 + 1/30 okanye i-1.03 microns.

Inkulungwane yewaka le-mm, elimalunga ne-0.00003937 ye-intshi. Ke impazamo xa ilinganisa ubude be-10mm ye-0.00103 mm okanye i-0.00004055 intshi. Yinto engaphantsi kwesiqingatha sesiqingatha se-tem-imposiso encinci!

Kwelinye icala, umntu kufuneka abe nokuchaneka i-10x into esizama ukuyilinganisa. Ke oko kuthetha ukuba sinokuthemba kuphela lo mlinganiso ukuya kwi-10x eloxabiso, okanye i-intshi ezingama-0.00005. Iseyimpazamo entle entle.

Izinto zifumana i-murkier yevenkile yevenkile ye-cmm. Ukuba i-CMM igcinwe kwilebhu yokuhlola yobushushu, inceda kakhulu. Kodwa kumgangatho wevenkile, amaqondo obushushu anokwahluka kakhulu. Kukho iindlela ezahlukeneyo ze-CMM zinokubuyisa ukwahluka kobushushu, kodwa akukho namnye ogqibeleleyo.

I-CMM DRORS zihlala zikhankanya ukuchaneka kwebhendi yobushushu, kunye ne-ISO 10360-2 ngokuhambelana kwe-ISMM ngokuchanekileyo, ibhendi eqhelekileyo yi-64-72F (18-22F). Ilungile ngaphandle kokuba umgangatho wakho wevenkile une-86f ehlotyeni. Ke awunayo i-propt elungileyo yempazamo.

Abanye abavelisi baya kukunika iseti yezitepsi okanye amaqondo obushushu amanqanaba ane-specials echanekileyo. Kodwa kwenzeke ntoni ukuba ukwinqanaba elingaphezulu kwesinye lokuqhuba kwezinye iindawo ngamaxesha ahlukeneyo omhla okanye iintsuku ezahlukeneyo zeveki?

Enye iqalisa ukudala uhlahlo-lwabiwo mali olungaqinisekanga oluvumela iimeko ezibi kakhulu. Ukuba ezo meko zimbi zikhokelela ekuqiniseni iinxalenye zakho, ezinye iinkcukacha zenkqubo ziyafuneka:

Unganciphisa umda we-CMM kumaxesha athile omhla xa iithes ziwela kumqolo ofanelekileyo.
Unokukhetha ukukhetha kuphela umatshini wokuphelisa okanye amanqaku ngamaxesha athile omhla.
I-CMM engcono inokuba neengxelo ezingcono zeqondo lobushushu. Basenokufanele ukuba bakufanelwe nangona benokwenzakala kakhulu.

Ewe kunjalo la manyathelo ayakuphinda enze isiphithiphithi kusenokwazi ukulungisa ngokuchanekileyo imisebenzi yakho. Ngequbuliso ucinga ukuba ulawulo lwemozulu lungcono kumgangatho wevenkile lunokuba lutyalo-mali olufanelekileyo.

Ungayibona indlela yonke le nto iyonke ifumana i-fussy ye-fussy.

Esi sithako esihamba ngesandla siyindlela yokuqikelela ukuba itshekishwe yi-CMM. Imigangatho yeGolide yindawo yokulinganisa yejometri kunye nokuthambisa (GD & T). Jonga ikhosi yethu yokwazisa kwi-GD & T ukuze ufunde ngakumbi.

Isoftware ye-CMM

I-CMM iqhuba iintlobo ezahlukeneyo zesoftware. Umgangatho ubizwa ngokuba yi-DMIS, emela umgangatho wokujonga umgangatho wokulinganisa. Ngelixa ayisiyo isoftware yesoftware nganye yomenzi we-CMM, uninzi lwayo ubuncinci luyixhasa.

Abavelisi benze iincasa zawo ezizodwa ukwenzela ukongeza imisebenzi yokulinganisa ayixhaswa yi-DMIS.

I-DMIS

Njengoko kuchaziwe i-DMIS, ngumgangatho, kodwa njenge-CNC ye-CNC ye-CNC, zininzi iilwimi ezibandakanya:

IPC-DMIS: Inguqulelo kaHexagon
I-Openvende
I-TOTEDDEMIC: Ingxokonkotha

I-MCOSMOS

I-Mcostmos yisoftware ye-wikon ye-nikon.

Calypso

I-Calypso yisoftware ye-CMS evela kuZeis.

I-cmm kunye nesoftware ye-CAM / Cam

Isoftware ye-CMM kunye neNkqubo ihambelana njani ne-Cad / cam yesoftware?

Zininzi iifomati zefayile ye-CAD, ke jonga ukuba zeziphi ii-cmm ze-CMM. Umdibaniso wokugqibela ubizwa ngokuba yiMpahla yemodeli (MBD). Nge-MBD, imodeli ngokwayo inokusetyenziselwa ukukhupha imilinganiselo ye-CMM.

I-MDB inomda ophambili, ngenxa yoko ayikasetyenziswa uninzi lwamatyala.

I-CMM I-CORMEes, i-fitxlelores, kunye nezinto ezichongiweyo

Cmm fied

Iintlobo ngeentlobo zeeprobes kunye neemilo ziyafumaneka ukuqhuba izicelo ezininzi ezahlukeneyo.

I-CMM ye-CMM

Izinto ezilungisiweyo zisindisa ixesha xa zilayisha kunye nokulayisha iinxalenye kwi-CMM, njengamatshini we-CNC. Unokufumana i-cmm ene-palter ye-pallet yokwandisa ukuqalisa.
