Ukulinganiswa kobuthambile kubhekisela esimweni lapho, ngaphansi kobubanzi obuthile besikhala sokuhlola, i-probe efana nepuleti ehamba phezulu naphansi icindezela isampula ekujuleni okuthile kwesikhala. Isamba sevektha sokumelana kwesampula namandla okugoba kanye namandla okungqubuzana phakathi kwesampula nesikhala siyalinganiswa. Leli nani limelela ubumnene bephepha.
Le ndlela isebenza ezinhlotsheni ezahlukene zephepha langasese elingagugi kanye nemikhiqizo yalo ephuma kulo, kanye neminye imikhiqizo yephepha enezidingo zokuthamba. Ayisebenzi kuma-napkin, izicubu zobuso ezigoqiwe noma ezifakwe i-embossed, noma iphepha elinokuqina okuphezulu.
1. Incazelo
Ubumnene bubhekisela esamba se-vector sokumelana nokugoba kwesampula uqobo kanye namandla okungqubuzana phakathi kwesampula kanye nesikhala lapho i-probe yokulinganisa efana nepuleti icindezelwa esikhaleni sobubanzi nobude obuthile kuya ekujuleni okuthile ngaphansi kwezimo ezichazwe yi-standard (iyunithi yamandla yi-mN). Uma leli nani lincane, isampula ithambile.
2. Izinsimbi
Ithuluzi lisebenzisaIsihloli sobumnene se-YYP-1000,eyaziwa nangokuthi ithuluzi lokulinganisa ubumnene bephepha le-microcomputer.
Ithuluzi kufanele lifakwe etafuleni elilinganayo nelizinzile, futhi akufanele libe ngaphansi kokudlidliza okubangelwa izimo zangaphandle. Amapharamitha ayisisekelo ethuluzi kufanele ahlangabezane nezidingo ezilandelayo.
3. Amapharamitha ezinsimbi kanye nokuhlolwa
3.1 Ububanzi Besikhala
(1) Ububanzi besikhala sokuhlola amathuluzi kufanele buhlukaniswe ngamagremu amane: 5.0 mm, 6.35 mm, 10.0 mm, kanye no-20.0 mm. Iphutha lobubanzi akufanele lidlule ±0.05 mm.
(2) Ububanzi besikhala kanye nephutha lobubanzi, kanye nokuhlolwa kokufana phakathi kwezinhlangothi ezimbili, kulinganiswa kusetshenziswa i-vernier caliper (ene-graduation engu-0.02 mm). Inani elimaphakathi lobubanzi emaphethelweni amabili kanye naphakathi kwesikhala ububanzi besikhala sangempela. Umehluko phakathi kwaso nobubanzi besikhala obujwayelekile kufanele ube ngaphansi kuka-±0.05 mm. Umehluko phakathi kwamanani aphezulu kanye namanani amancane phakathi kwezilinganiso ezintathu yinani lephutha lokufana.
3.2 Isimo se-probe esimise okwepuleti
Ubude: 225 mm; Ubukhulu: 2 mm; Irediyasi ye-arc yomphetho wokusika: 1 mm.
3.3 Isivinini sokuhamba esimaphakathi se-probe kanye nebanga lokuhamba eliphelele
(1) Ububanzi besivinini sokuhamba esimaphakathi kanye nebanga lokuhamba eliphelele le-probe, isivinini sokuhamba esimaphakathi: (1.2 ± 0.24) mm/s; ibanga lokuhamba eliphelele: (12 ± 0.5) nm.
(2) Ukuhlolwa kwebanga eliphelele lokuhamba kanye nesivinini sokuhamba esimaphakathi sekhanda lokulinganisa
① Okokuqala, setha i-probe endaweni ephezulu kakhulu yebanga lokuhamba, kala ukuphakama h1 kusukela ebusweni obuphezulu kuya phezulu kwetafula usebenzisa i-height gauge, bese wehlisa i-probe uye endaweni ephansi kakhulu yebanga lokuhamba, kala ukuphakama h2 phakathi kobuso obuphezulu ne-tabletop, bese ibanga lokuhamba lilonke (ngama-mm) lingu: H=h1-h2
② Sebenzisa iwashi lokumisa ukuze ulinganise isikhathi esithathwa yi-probe ukuze sisuke endaweni ephezulu kakhulu siye endaweni ephansi kakhulu, ngokunemba kwemizuzwana engu-0.01. Vumela lesi sikhathi sichazwe njengo-t. Khona-ke isivinini sokuhamba esimaphakathi (mm/s) singu: V=H/t
3.4 Ukujula Kokufakwa Ku-Slot
① Ukujula kokufakwa kufanele kube ngu-8mm.
② Ukuhlolwa kokujula kokufakwa endaweni yokufaka. Usebenzisa i-vernier caliper, kala ukuphakama u-B kweprobe emise okwepuleti uqobo. Ukujula kokufakwa kungu: K=H-(h1-B)
4. Ukuqoqwa Kwesampula, Ukulungiswa Nokucubungula
① Thatha amasampula ngokwendlela ejwayelekile, ucubungule amasampula, bese uwahlola ngaphansi kwezimo ezijwayelekile.
② Sika amasampula abe yizicucu zesikwele ezingama-100 mm × 100 mm ngokwesibalo sezingqimba esichazwe kuzinga lomkhiqizo, bese uphawula izinkomba ezinde neziphambeneyo. Ukuphambuka kosayizi ohlangothini ngalunye kufanele kube ngu-±0.5 mm.
③ Xhuma ugesi ngokwencwadi yemiyalelo yesihloli sokuthamba se-PY-H613, fudumeza kusengaphambili isikhathi esibekiwe, bese ulungisa iphuzu elingu-zero lethuluzi, bese ulungisa ububanzi besikhala ngokwezidingo zekhathalogi yomkhiqizo.
④ Beka amasampula epulatifomu yomshini wokuhlola ubumnene, bese uwabeka ngokulinganayo ngangokunokwenzeka endaweni evulekile. Kumasampula anezingqimba eziningi, wabeke ngendlela ephezulu nephansi. Setha iswishi yokulandelela i-peak yethuluzi endaweni ephakeme, cindezela inkinobho yokuqala, bese i-probe efana nepuleti yethuluzi iqala ukuhamba. Ngemva kokuthi isihambise lonke ibanga, funda inani lokulinganisa kusuka kusibonisi, bese ulinganisa isampula elandelayo. Kala amaphuzu edatha ayi-10 ngezindlela ezinde neziphambene ngokulandelana, kodwa ungaphindi isilinganiso sesampula efanayo.
