Isisekelo Sebhuloho Le-Precision Granite Semishini Yokulinganisa Ehlanganisiwe

Isakhiwo Esakhelwe Ukuhlala Singanyakazi

Yonke imishini yokulinganisa i-coordinate inembe njengohlaka olumi kulo. Lena yingxenye yomshini okungekho muntu okhuluma ngayo emibukisweni yezohwebo - azikho izinjini ze-servo, azikho izinzwa, azikho izinto ezikhanyisayo - kodwa yingxenye eyodwa enquma ukuthi zonke ezinye izinhlelo ku-CMM zingaletha yini ukunemba okushicilelwe ephepheni layo le-spec. Yilokho okwakhelwe khona lesi sisekelo sebhuloho.

Yenziwe ngomshini oqinile we-granite emnyama ejiyile, le ngxenye yakha isakhiwo sebhuloho lesitayela se-gantry esivame ukutholakala kuma-CMM anengalo evundlile kanye nohlobo lwebhuloho: amakholomu amabili okusekela aqonde phezulu avela epuletini elibanzi lesisekelo, axhunywe ngomshayo ophezulu ovundlile othwala i-axis yebhuloho elihambayo lomshini. Imisele enemicu egijima ngomshayo ophezulu ayihlobisi — iyiziteshi zokuqondisa eziqondile zomhlabathi lapho uhlelo lokunyakaza oluqondile lomshini luhamba khona, okusho ukuthi ukunemba kwawo kanye nokuhambisana kwawo kufanele kubambe ngaphakathi kwama-micron kulo lonke ubude bomshayo, hhayi nje ezindaweni ezimbalwa zesampula.

Lokho Okubhekayo Empeleni

Uma ubheka ingxenye ngokwayo, ipuleti lesisekelo liphethe igridi ebanzi yemigodi yokufaka enezintambo egijima phezu kobuso bayo obugcwele — iphethini evumela abahlanganisi ukuthi babophe izinto zokufakelwa, ama-clamp omsebenzi, noma izesekeli zokulinganisa zesibili noma kuphi etafuleni ngaphandle kokudinga umsebenzi wokubhoboza ngokwezifiso kuzo zonke izinhlelo zokusebenza. Amakholomu amabili ngalinye linembobo enkulu yokukhanyisa phakathi nendawo, okunciphisa isisindo ngaphandle kokuphazamisa ukuqina kwekholomu — imininingwane ebaluleke kakhulu kunalokho okufanele ibukeke ngakho, njengoba ikhilogremu ngayinye esusiwe esakhiweni esingaguquki iyikhilogremu uhlelo lokulawula izinga lokushisa lomshini akudingeki luzinze.

Ukuphela kobuso kuyi-grind encane, ehambisanayo emnyama engacwebezeli ebusweni bonke — akukho micu yokupholisha, akukho zimpawu zamathuluzi ezibonakalayo, akukho ukuhlukahluka kombala phakathi kwezingxenye, okuvame ukuba yisibonakaliso esibonakalayo esinengqondo (nakuba kungakaze kuthathe indawo yesitifiketi sangempela sokulinganisa) sokuthi ibhloko ligaywe ku-grinder eyodwa enkulu egcinwe kahle kunokuba ihlanganiswe kusuka esitokweni esingalingani. Kufakwe epuletini eliyisisekelo esithombeni sokubhekisela kukhona i-rail guide rail eqondile enekhanda le-probe elifakiwe — eliboniswe lapha ukuze kuboniswe ukuthi isakhiwo se-granite esiqediwe sihlangana kanjani nezingxenye zokunyakaza nokuzwa ikhasimende elizozifaka ngesikhathi sokuhlanganiswa komshini.

Kungani I-Granite Esikhundleni Sensimbi Ehlanganisiwe

Uhlaka lwebhuloho lensimbi ehlanganisiwe noma ehlanganisiwe lushibhile ngaphambili futhi lushesha ukulwenza, kodwa luza nezinkinga ezimbili ezingabonakali kuze kube yilapho umshini ususebenze isikhathi eside: ukucindezeleka kokushisela kwangaphakathi okunciphisa kancane ezinyangeni futhi kubangele ukuthi uhlaka luhambe kancane, kanye nesilinganiso sokunwebeka kokushisa cishe siphindwe kabili kunesegranite exineneyo. Ezingxenyeni zokulinganisa ze-CMM kuya ekubekezeleleni kwe-micron enenombolo eyodwa, noma iyiphi yalezo zinkinga yanele ukwenza imininingwane yokunemba komshini ingabi namsebenzi phakathi nonyaka wokufakwa. Igranite ayinayo ingcindezi yangaphakathi yokunciphisa - yayisivele yakhiwe ngaphansi kwengcindezi yemvelo yemvelo - futhi i-coefficient yayo ephansi, eqinile yokwanda kokushisa isho ukuthi isakhiwo sigcina i-geometry yaso ngokushintshashintsha okuvamile kwansuku zonke kokushisa phansi esitolo, hhayi ngaphakathi kwelebhu elawulwa yisimo sezulu kuphela.
