Izixhobo ezizinzileyo zokwakha. Qiniseka ukuba amalungu eprayimari yolwakhiwo lomatshini aqukethe izixhobo ezingaphantsi kohlukaniso lwamaqondo obushushu. Cinga ngebhulorho (umatshini X-Axis), ibhulorho ixhasa, isikhokelo sikaloliwe (umatshini y-axis), iibherithi kunye ne-Z-Axis ye-Z-Axis ye-Z-Axis. La macandelo achaphazela ngokuthe ngqo imilinganiselo yoomatshini kunye neengcambu zokuchaneka, kwaye ubeke izinto ze-CMM.
Iinkampani ezininzi zenza ezi zinto ngaphandle kwe-aluminium ngenxa yobunzima bayo, oomancination kunye neendleko eziphantsi. Nangona kunjalo, izixhobo ezifana neGranite okanye i-ceramic zingcono kakhulu kwii-CMMS ngenxa yokwabelana ngebrorm. Ukongeza kwinyaniso yokuba i-Aluminiyam yanda phantse kangangezihlandlo ezine ngaphezulu kweGranite, i-granite ineempawu eziguquguqukayo kwaye zinokubonelela ngendawo ethe tyaba enokuhamba ngayo. I-Granite inayo, enyanisweni, yayingumgangatho owamkelwe ngokubanzi womlinganiso kangangeminyaka.
Kwi-CMMS, nangona kunjalo, igrantiite inomtsalane omnye - inzima. Ingxaki yengxaki iya kuba nakho, nokuba ngu-isandla okanye nge-servo, ukuhambisa i-granite cmm kwi-axes yayo ukuthatha imilinganiselo. Umbutho omnye, i-LS Starrett Co., ifumene isisombululo esinomdla kule ngxaki: Itekhnoloji yeGranter Grantite.
Itekhnoloji isebenzisa iipleyiti zegranite zegranite kunye nemiqadi eyenziwe kwaye ihlanganisene ukuze yenze amalungu amdaka ekwakheni. Ezi zakhiwo zezakhiwo zinobunzima obufana ne-aluminium ngelixa zigcina iimpawu ezintle ze-grancite. I-Starrett isebenzisa le teknoloji yawo zombini amalungu ebhulorho kunye ne-Blorhogege. Kwindlela efanayo, basebenzisa i-cermic ye-ceramic yebhulorho kwezona ram ezinkulu xa i-graftite grafti ayinantsingiselo.
Iibheringi. Phantse bonke abavelisi be-CMM bashiye iinkqubo ze-roller ezidala emva, bekhetha iinkqubo eziphakamileyo kakhulu. Ezi nkqubo zifuna ukunxibelelana phakathi kwengqumbo kunye ne-Iberver ngexesha lokusetyenziswa, kukhokelela kwi-zero. Ukongeza, iibherithi zomoya azinazinxalenye ezihambayo kwaye, ke, akukho ngxolo okanye i-cudtions.
Nangona kunjalo, iibherithi zomoya nazo zinokwahluka kwazo ngokwendalo. Ngokufanelekileyo, jonga inkqubo esebenzisa igrafu egcwele igrafu njengento ethengisayo endaweni ye-aluminium. Igrafu kule mpahla ivumela umoya oxinzelelweyo ukuba udlule ngokuthe ngqo kwindalo yendalo kwigrafiki, ekhokelela kwicala elisasazeke kakhulu lomoya kuwo wonke umhlaba. Kwakhona, ungqameko lomoya okhuthazo oluveliselweyo lumncinci kakhulu-malunga ne-0.0002 ". Kwelinye icala le-Aluminium Brits, kwelinye icala, ihlala inomjelo womoya phakathi kwe-0.0010 "ne-0.0030". Isithuba somoya esincinci sikhethekile kuba inciphisa utyekelo lomatshini lokugqobhoza i-sushion yomoya kwaye iphumela kwi-rigid eqinile, echanekileyo kunye nephindaphindiweyo.
Incwadi ye-vs. dcc. Ukuchonga ukuba ukuthenga i-CMM ye-CMM okanye i-automated ilungelelaniswe ngokuthe ngqo. Ukuba imeko yakho yemveliso eyintloko yemveliso ijolise kuMatshini olawulwa ngekhompyuter yekhompyuter yeyona ndlela yakho ilungileyo ekuhambeni kwexesha, nangona iindleko zokuqala ziya kuba ngaphezulu. I-CMMS yencwadi ilungele ukuba iza kusetyenziswa ngokuyintloko ukuze ufumane umsebenzi wokuhlola okokuqala okanye ukuguqula ubunjineli. Ukuba wenza njalo kancinci kwaye ungafuni ukuthenga oomatshini ababini, qwalasela i-DCC CMM nge-servo drives, ivumela ukusetyenziswa kwezandla xa kufuneka.
Inkqubo yokuqhuba. Xa ukhetha i-dcc cmm, jonga umatshini ngaphandle kwe-hysteresis (i-backlash) kwinkqubo yokuqhuba. I-hysteresis ichaphazela kakubi ubume bendawo yokuchaneka koomatshini kunye nokuphindaphinda. Iidrives uqhuba zisebenzisa i-shaft yokuqhuba ngokuthe ngqo kwi-right ye-rives, ikhokelela kwi-zero hysteresis kunye ne-vibrary encinci
